  • Finding a Payment Gateway?

    - by Lynda
    I have a client who would like to sell glass pipes online. The problem I run into is with the payment gateway. Glass pipes fall into two categories drug paraphernalia or tobacco product. This leads me to here and asking: Does anyone know of a payment gateway that will process payments for glass pipes? Note: Doing some Google searching I read that Authorize.net will accept tobacco but when I spoke with them they said they do not.

  • PeopleSoft Grants & the Federal Agency Letter of Credit Draw Changes

    - by Mark Rosenberg
    For decades, most, if not all, US Federal agencies that sponsor research allowed grant recipients to request and receive payments using pooled accounts, commonly known as pooled letter of credit (LOC) draws. This enabled organizations, such as universities and hospitals, fast and efficient access to reimbursement of the expenditures they incurred conducting research across a portfolio of grants. To support this business practice, the PeopleSoft Grants solution has delivered an LOC Draw report to provide the total request amount along with all of the supporting invoice details for reconciliation and audit purposes. Now, in an attempt to provide greater transparency, eliminate fraud, strengthen accountability for grant-related financial transactions, and simplify grant award closeout, many US Federal sponsors are transitioning from the “pooling” letter of credit draw method to requesting on a “grant-by-grant” basis. The National Science Foundation, the second largest issuer of Federal awards, already transitioned to detailed grant draws in 2013. And, in response to the U.S. Department of Health and Human Services (HHS) directive to HHS-supported Agencies, the largest Federal awards sponsor, the National Institutes of Health (NIH), will fully transition to the new HHS subaccount draw method. This will require NIH award recipients to request payments based on actual expenses incurred on an award-by-award basis. NIH is expected to fully transition to this new draw method by the end of Federal fiscal year 2015.  (The NIH had planned to fully transition to this new method by the end of fiscal 2014; however, the impact to institutions was deemed to be significant enough that a reprieve was recently granted.) In light of these new Federal draw requirements, we have recently released these new features to aid our customers on both PeopleSoft Grants releases 9.1 and 9.2:1. Federal Award Identification Number on the Proposal and Award Profile 2. Letter of credit fields on contract lines to support award basis draws and comply with Federal close out mandates3. Process to produce both pro forma and final LOC Draw Reports in BI Publisher report format4. Subacccount ID field on the LOC Summary and a new BI Publisher version of the LOC Summary report 5. Added Subaccount Field and contract info to be displayed on the LOC summary page6. Ability to generate by a variety of dimensions pro forma and invoiced draw listings 7. Queries for generation and manipulation of data to upload into sponsor payment request systems and perform payment matching8. Contracts LOC Close Out query to quickly review final balances prior to initiating final draws and preparing Federal Financial Reports prior to close The PeopleSoft Development team actively monitors this and other major Federal changes and continues working closely with the Grants Product Advisory Group of the Higher Education User Group to ensure a clear understanding of what our customers need in order to transition to new approaches for doing business with the Federal government. For more information regarding the enhancements to the PeopleSoft Grants solution, existing customers can login to My Oracle Support and review the Enhancements to Letter of Credit Process (Doc ID 1912692.1) associated with resolution ID 904830. This enhanced LOC functionality is available in both PeopleSoft FSCM 9.1 Bundle #31 and PeopleSoft FSCM 9.2 Update Image 8.

  • Using only password to authenticate user (no "username" field)

    - by Guy
    I am creating a client access system, to allow manage invoices, make payments, access information about their products and information/functionality alike. Supposedly there are less than 1000 clients. Would there be any security threat to use only password (UUID v4 strings) to authenticate user? My thoughts: There is virtually no probability of collision or success with brute-force attack. http://en.wikipedia.org/wiki/UUID#Random%5FUUID%5Fprobability%5Fof%5Fduplicates User friendly (one click go) It is not intended to be remembered

  • Is there a way to take credit cards on my website without needing a merchant account/payment gateway?

    - by Erik
    I've been looking for a service like this but can't find one -- it boggles my mind that such a thing doesn't exist. The ideal thing I'm looking for would be something like this: User fills out a form on my website I submit data to the service (cc #, payment amount) I get paid perhaps monthly by the service the amounts that were charged (less a fee) This is more or less how accepting paypal for payments works, except it takes my users to paypal's site and forces them to create a paypal account etc, which I'd like to avoid. Does such a service exist?

  • Integrating with a payment provider; Proper and robust OOP approach

    - by ExternalUse
    History We are currently using a so called redirect model for our online payments (where you send the payer to a payment gateway, where he inputs his payment details - the gateway will then return him to a success/failure callback page). That's easy and straight-forward, but unfortunately quite inconvenient and at times confusing for our customers (leaving the site, changing their credit card details with an additional login on another site etc). Intention & Problem description We are now intending to switch to an integrated approach using an exchange of XML requests and responses. My problem is on how to cater with all (or rather most) of the things that may happen during processing - bearing in mind that normally simplicity is robust whereas complexity is fragile. Examples User abort: The user inputs Credit Card details and hits submit. An XML message to the provider's gateway is sent and waiting for response. The user hits "stop" in his browser or closes the window. ignore_user_abort() in PHP may be an option - but is that reliable? might it be better to redirect the user to a "please wait"-page, that in turn opens an AJAX or other request to the actual processor that does not rely on the connection? Database goes away sounds over-complicated, but with e.g. a webserver in the States and a DB in the UK, it has happened and will happen again: User clicks together his order, payment request has been sent to the provider but the response cannot be stored in the database. What approach could I use, using PHP to sort of start an SQL like "Transaction" that only at the very end gets committed or rolled back, depending on the individual steps? Should then neither commit or roll back have happened, I could sort of "lock" the user to prevent him from paying again or to improperly account for payments - but how? And what else do I need to consider technically? None of the integration examples of e.g. Worldpay, Realex or SagePay offer any insight, and neither Google or my search terms were good enough to find somebody else's thoughts on this. Thank you very much for any insight on how you would approach this!

  • Is it possible to run my Windows Form application in Windows CE platform?

    - by Fakhrul
    I am new in Windows CE development and never done it yet. Need some advise from the expert in here. In our current project, we are developing a client-server application. The client side is using a windows form application that are base on Windows XP OS while the server is a web base application. This question are related to the client application (Windows Form). This application are using Sql Server Express Edition for data storage. The data is stored in XML object format. It also can transfer a data from client to server via web service. It also interact with hardware such as Magnetic Stripe Reader, Contactless Smart Card Reader, and a thermal printer. Most of the communication between hardware device and systems are base on Serial Port. It is use standard app.config for the configuration and is a multi threaded application. There is a new requirement to use a Handheld device which is use a Windows CE platform. This handheld included the required equipment such as Contactless Smart Card Reader, Printer and Magnetic Stripe Reader. Instead of developing a new client application, is it possible to me to convert my current application that are base on Windows XP to Windows CE? If yes, how can I do that? If no, is it any other brilliant suggestion to do this? Thanks in advance. Software Engineer

  • CSS Width Greater then Page Width without Horizontal Scroll (overflow:hidden not an option)

    - by Anders H
    I've got a basic layout going in 960.gs. One line of text is absolutely positioned, starting within an inner DIV and exiting only the right side of the page. Here's a screenshot: The issue is that as the text appears as a series of unbroken words, if the width of the text box doesn't extend beyond the end of the page, it breaks some distance from the edge. overflow: hidden; doesn't do the trick because I need to set the width wider than the page. float won't work because the text can't escape the width of the inner DIV. I can't set it outside the inner DIV and just position it there as the same problem will still exist. The code is basically as simple as: <wrapper (containing) DIV> <text stripe DIV> <p></p> </text stripe DIV> </ wrapper DIV> I know I've done something like this before and I can't for the life of me remember what I ended up doing. Thanks.

  • Striped table rows in ASP.NET MVC (without using jQuery or equivalent)

    - by Richard Ev
    When using an ASP.NET WebForms ListView control to display data in an HTML table I use the following technique in to "stripe" the table rows: <ItemTemplate> <tr class="<%# Container.DisplayIndex % 2 == 0 ? "" : "alternate" %>"> <!-- table cells in here --> </tr> </ItemTemplate> With the following CSS: tr.alternate { background-color: #EFF5FB; } I have just gone through the ASP.NET MVC Movie Database Application tutorial and learnt that in MVC-land table rows can be (must be?) constructed as follows: <% foreach (var item in Model) { %> <tr> <td> <%= Html.Encode(item.Title) %> </td> <!-- and so on for the rest of the table cells... --> </tr> <% } %> What can I add to this code to stripe the rows of my table? Note: I know that this can be done using jQuery, I want to know if it can be done another way. Edit If jQuery (or equivalent) is in your opinion the best or most appropriate post, I'd be interested in knowing why.

  • Quantifying the effects of partition mis-alignment

    - by Matt
    I'm experiencing some significant performance issues on an NFS server. I've been reading up a bit on partition alignment, and I think I have my partitions mis-aligned. I can't find anything that tells me how to actually quantify the effects of mis-aligned partitions. Some of the general information I found suggests the performance penalty can be quite high (upwards of 60%) and others say it's negligible. What I want to do is determine if partition alignment is a factor in this server's performance problems or not; and if so, to what degree? So I'll put my info out here, and hopefully the community can confirm if my partitions are indeed mis-aligned, and if so, help me put a number to what the performance cost is. Server is a Dell R510 with dual E5620 CPUs and 8 GB RAM. There are eight 15k 2.5” 600 GB drives (Seagate ST3600057SS) configured in hardware RAID-6 with a single hot spare. RAID controller is a Dell PERC H700 w/512MB cache (Linux sees this as a LSI MegaSAS 9260). OS is CentOS 5.6, home directory partition is ext3, with options “rw,data=journal,usrquota”. I have the HW RAID configured to present two virtual disks to the OS: /dev/sda for the OS (boot, root and swap partitions), and /dev/sdb for a big NFS share: [root@lnxutil1 ~]# parted -s /dev/sda unit s print Model: DELL PERC H700 (scsi) Disk /dev/sda: 134217599s Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 63s 465884s 465822s primary ext2 boot 2 465885s 134207009s 133741125s primary lvm [root@lnxutil1 ~]# parted -s /dev/sdb unit s print Model: DELL PERC H700 (scsi) Disk /dev/sdb: 5720768639s Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 34s 5720768606s 5720768573s lvm Edit 1 Using the cfq IO scheduler (default for CentOS 5.6): # cat /sys/block/sd{a,b}/queue/scheduler noop anticipatory deadline [cfq] noop anticipatory deadline [cfq] Chunk size is the same as strip size, right?

  • Linux RAID-0 performance doesn't scale up over 1 GB/s

    - by wazoox
    I have trouble getting the max throughput out of my setup. The hardware is as follow : dual Quad-Core AMD Opteron(tm) Processor 2376 16 GB DDR2 ECC RAM dual Adaptec 52245 RAID controllers 48 1 TB SATA drives set up as 2 RAID-6 arrays (256KB stripe) + spares. Software : Plain vanilla 2.6.32.25 kernel, compiled for AMD-64, optimized for NUMA; Debian Lenny userland. benchmarks run : disktest, bonnie++, dd, etc. All give the same results. No discrepancy here. io scheduler used : noop. Yeah, no trick here. Up until now I basically assumed that striping (RAID 0) several physical devices should augment performance roughly linearly. However this is not the case here : each RAID array achieves about 780 MB/s write, sustained, and 1 GB/s read, sustained. writing to both RAID arrays simultaneously with two different processes gives 750 + 750 MB/s, and reading from both gives 1 + 1 GB/s. however when I stripe both arrays together, using either mdadm or lvm, the performance is about 850 MB/s writing and 1.4 GB/s reading. at least 30% less than expected! running two parallel writer or reader processes against the striped arrays doesn't enhance the figures, in fact it degrades performance even further. So what's happening here? Basically I ruled out bus or memory contention, because when I run dd on both drives simultaneously, aggregate write speed actually reach 1.5 GB/s and reading speed tops 2 GB/s. So it's not the PCIe bus. I suppose it's not the RAM. It's not the filesystem, because I get exactly the same numbers benchmarking against the raw device or using XFS. And I also get exactly the same performance using either LVM striping and md striping. What's wrong? What's preventing a process from going up to the max possible throughput? Is Linux striping defective? What other tests could I run?

    looking for recommendations on ESX4 OS - VMFS version3: RAID-5 : matching the stripe size with VMFS block size? (64K, 128K etc) RAID controller options: "adaptive read ahead, write-back" on PERC 6i 90% VMs on server are Windows (2008, 2003, Vista etc, SQL 2005 etc) i have read that smaller stipes are good for writes and larger for reads. Since this is virtual env, not sure whats good.

  • Raid0 setup - What should 'my computer' say?

    - by superexsl
    Hey, I'm not a hardware person, so maybe someone here could help me. I ordered a PC from Dell that has "Serial ATA Raid 0 "Stripe"(7200RPM)Dual HDD" (2x500gb). However, I've just noticed that there's only one HD of 1TB (which is the default option when ordering). Should I be seeing two HDDs in "My Computer" or does the Raid0 setup simply improve performance rather than have (and display) two individual HDDs? How can I check if my computer does have a 'raid0' setup? Thanks

  • Comparing Isis, Google, and Paypal

    - by David Dorf
    Back in 2010 I was sure NFC would make great strides, but here we are two years later and NFC doesn't seem to be sticking. The obvious reason being the chicken-and-egg problem.  Retailers don't want to install the terminals until the phones support NFC, and vice-versa. So consumers continue to sit on the sidelines waiting for either side to blink and make the necessary investment.  In the meantime, EMV is looking for a way to sneak into the US with the help of the card brands. There are currently three major solutions that are battling in the marketplace.  All three know that replacing mag-stripe alone is not sufficient to move consumers.  Long-term it's the offers and loyalty programs combined with tendering that make NFC attractive. NFC solutions cross lots of barriers, so a strong partner system is required.  The solutions need to include the carriers, card brands, banks, handset manufacturers, POS terminals, and most of all lots of merchants.  Lots of coordination is necessary to make the solution seamless to the consumer. Google Wallet Google's problem has always been that only the Nexus phone has an NFC chip that supports their wallet.  There are a couple of additional phones out there now, but adoption is still slow.  They acquired Zavers a while back to incorporate digital coupons, but the the bulk of their users continue to be non-NFC.  They have taken an open approach by not specifying particular payment brands.  Google is piloting in San Francisco and New York, supporting both MasterCard PayPass and stored value. I suppose the other card brands may eventually follow.  There's no cost for consumers or merchants -- Google will make money via targeted ads. Isis Not long after Google announced its wallet, AT&T, Verizon, and T-Mobile announced a joint venture called Isis.  They are in the unique position of owning the SIM in the phones they issue.  At first it seemed Isis was a vehicle for the carriers to compete with the existing card brands, but Isis later switched to a generic wallet that supports the major card brands.  Isis reportedly charges issuers a $5 fee per customer per year.  Isis will pilot this summer in Salt Lake City and Austin. PayPal PayPal, the clear winner in the online payment space beyond traditional credit cards, is trying to move into physical stores.  After negotiations with Google to provide a wallet broke off, PayPal decided to avoid NFC altogether, at least for now, and focus on payments without any physical card or phone.  By avoiding NFC, consumers don't need an NFC-enabled phone and merchants don't need a new reader.  Consumers must enter their phone number and PIN in the merchant's existing device, or they can enter their PIN in the PayPal inStore app running on their phone, then show the merchant a unique barcode which authorizes payment. Paypal is free for consumers and charges a fee for merchants.  Its not clear, at least to me, how PayPal handles fraudulent transactions and whether the consumer is protected. The wildcard is, of course, Apple.  Their mobile technologies set the standard, so incorporating NFC chips would certainly accelerate adoption of many payment solutions.  Their announcement today of the iOS Passbook is a step in the right direction, but stops short of handling payments. For those retailers that have invested in modern terminals, it seems the best strategy is to support all the emerging solutions and let the consumers choose the winner.

  • Preserving case in HTTP headers with Ruby's Net:HTTP

    - by emh
    Although the HTTP spec says that headers are case insensitive; Paypal, with their new adaptive payments API require their headers to be case-sensitive. Using the paypal adaptive payments extension for ActiveMerchant (http://github.com/lamp/paypal_adaptive_gateway) it seems that although the headers are set in all caps, they are sent in mixed case. Here is the code that sends the HTTP request: headers = { "X-PAYPAL-REQUEST-DATA-FORMAT" => "XML", "X-PAYPAL-RESPONSE-DATA-FORMAT" => "JSON", "X-PAYPAL-SECURITY-USERID" => @config[:login], "X-PAYPAL-SECURITY-PASSWORD" => @config[:password], "X-PAYPAL-SECURITY-SIGNATURE" => @config[:signature], "X-PAYPAL-APPLICATION-ID" => @config[:appid] } build_url action request = Net::HTTP::Post.new(@url.path) request.body = @xml headers.each_pair { |k,v| request[k] = v } request.content_type = 'text/xml' proxy = Net::HTTP::Proxy("127.0.0.1", "60723") server = proxy.new(@url.host, 443) server.use_ssl = true server.start { |http| http.request(request) }.body (i added the proxy line so i could see what was going on with Charles - http://www.charlesproxy.com/) When I look at the request headers in charles, this is what i see: X-Paypal-Application-Id ... X-Paypal-Security-Password... X-Paypal-Security-Signature ... X-Paypal-Security-Userid ... X-Paypal-Request-Data-Format XML X-Paypal-Response-Data-Format JSON Accept */* Content-Type text/xml Content-Length 522 Host svcs.sandbox.paypal.com I verified that it is not Charles doing the case conversion by running a similar request using curl. In that test the case was preserved.

  • jQuery validation plugin and .ajax

    - by FALCONSEYE
    So, I have a form where I load divs as I go asking for various user input and displaying some offers. I have the following: $("#calcPrice").click(function() { $("#invPricing").validate({ rules: { ... }, messages: {... } , submitHandler: function(form) { .... $.ajax({ }); $.ajax({ }); return false; } }); My problem is after validation, none of the ajax calls work. If I remove the validation methods (rules, messages, submitHandler), everything works fine. Can somebody tell me what I am missing here? thanks in advance. btw, these are the ajax calls: $.ajax({ dataType: "json", type: "get", url: <cfoutput>"#actURL#"</cfoutput>, data: formData+"&p_type=LOW&returnJSON=true", cache: false, success: function(result) { // fields to populate: $("#rent").val(result.RENT); $("#discount").val(result.DISCOUNT); $("#salesPrice1").val(result.SALESPRICE); $("#cashPrice1").val(result.CASHSALESPRICE); $("#tax1").val(result.SALESTAX); $("#payment1").val(result.PAYMENTS); } , error: function(xmlHttpRequest, status, err) { confirm('Error!' + err); } }); $.ajax({ dataType: "json", type: "get", url: <cfoutput>"#actURL#"</cfoutput>, data: formData+"&p_type=HIGH&returnJSON=true", cache: false, success: function(result) { // fields to populate: $("#rent").val(result.RENT); $("#discount").val(result.DISCOUNT); $("#salesPrice2").val(result.SALESPRICE); $("#cashPrice2").val(result.CASHSALESPRICE); $("#tax2").val(result.SALESTAX); $("#payment2").val(result.PAYMENTS); } , error: function(xmlHttpRequest, status, err) { confirm('Error!' + err); } }); I am basically displaying two offers one Low, one High.

  • Code Trivia: optimize the code for multiple nested loops

    - by CodeToGlory
    I came across this code today and wondering what are some of the ways we can optimize it. Obviously the model is hard to change as it is legacy, but interested in getting opinions. Changed some names around and blurred out some core logic to protect. private static Payment FindPayment(Order order, Customer customer, int paymentId) { Payment payment = Order.Payments.FindById(paymentId); if (payment != null) { if (payment.RefundPayment == null) { return payment; } if (String.Compare(payment.RefundPayment, "refund", true) != 0 ) { return payment; } } Payment finalPayment = null; foreach (Payment testpayment in Order.payments) { if (testPayment.Customer.Name != customer.Name){continue;} if (testPayment.Cancelled) { continue; } if (testPayment.RefundPayment != null) { if (String.Compare(testPayment.RefundPayment, "refund", true) == 0 ) { continue; } } if (finalPayment == null) { finalPayment = testPayment; } else { if (testPayment.Value > finalPayment.Value) { finalPayment = testPayment; } } } if (finalPayment == null) { return payment; } return finalPayment; } Making this a wiki so code enthusiasts can answer without worrying about points.

  • Currency exchange rates for paypal

    - by Jacco
    Does anyone know a way to get the currency exchange rates for paypal? We have custom shopping cart and use Paypal (Website Payments Standard) to handle payments. Our 'home' currency is Euro, but we would like to present our customers the option to pay in different currencies (USD, CAD, AUD and GBP). PayPal offers the option to:     a) automatically convert our Euro quoted prices to, for example, USD upon checkout     b) checkout in USD directly With option a): We get paid in Euro, the customer pays for the currency exchange (good). The customer does not know what he/she is going to be charged in USD until checkout. (bad) With option b) The customer pays in USD, then the currency is converted into EUR and we pay the the currency exchange. The customer never has to worry about the different currencies (excellent) We do not know the exchange rate PayPal is going to use so we cannot quote the correct prices to our customer (showstopper) So my question is:   Does anybody know a way to get the PayPal exchange rates? or   Does anybody know how to make a good estimate? Update: PayPal updates it's exchange rate 2 times a day. (at least, that is what they state). They use the Interbank Exchange Rate provided by ??? and add a 2.5% spread above this rate to determine their retail foreign exchange rates. Unforunately, there the Interbank Exchange Rates vary from source to source and from minute to minute. We have been monitoring the PayPal exchange rates and cross referenced them with the Official reference rates provides by the European Central Bank. the results vary widely, somewhere from 1 to 6 ! percent...

  • MySQL where condition but not limited by it

    - by Manny Calavera
    Hello. I would like to run a query on my database like this: SELECT SUM( t1.value ) AS total1, SUM( t2.value ) AS total2, SUM( t3.value ) AS total3, SUM( t4.value ) AS total4 FROM pay1 t1, pay2 t2, pay3 t3, pay4 t4 WHERE t1.date = '2010-04-29' AND t2.date = '2010-04-29' AND t3.date = '2010-04-29' AND t4.date = '2010-04-29' I am generating a report on payments and I would like to see a total of payments from each table based on the matching date. The problem is that some of the tables would not meet the condition of date and I want them to show up with 0 value if not. Currently, if any of the tables does not match the date, I get 0 results. I want to display value of 0 anywhere the date is not met and other fields should appear with the found values. The perfect operand for me would be "ANDOR" so that it won't be limited by any date that doesn't math in any table. Unfortunately, ANDOR does not exist as I am aware of so what should I do ? Can anyone help ? Thanks.

  • Building Paypal based membership website - total noob - would appreciate help

    - by Ali
    this is a follow up on my question on paypal integration. I'm working ona membership site for racing fans. My membership site has 3 membership levels - free, gold and premium. When a user signs up he/she can gets a free membership on the spot but has the option to upgrade to a gold membership for 4 Dollars a month or a premium membership for 10 Dollars a month. I've gone through the paypal integration guide a few times though and have a vague understanding of how to get this to work. I think the recurring payments option would be fine enough - however I don't know how do I implement this in my system. Like when a user decides to go for a paid account i.e. Gold or premium from basic - what should I do on both my code side and on the paypal account side - I'd really appreciate if anyone would outline what I'd have to do here. Plus when a user decides to upgrade from lets say a Gold to a premium account - there is the issue of computing how much should be charged to upgrade his/her account eg: a user has been billed for 4 dollars and the next day opts to go for a premium account so assuming that the surplus for the rest of the month is 5 dollars and further from that all payments would be recurring 10 dollars monthly - how do I implement this? And in case a user decides to downgrade from a premium account of 10 dollars a month to a gold account of 4 dollars a month - how do I handle the surplus which would have to be refunded for that month alone and changing the membership? And like wise if someone wishes to cancel membership and go to having a free account - how do I refund whatever is owed and cancel the subscription. I'm sorry if it sounds like I'm asking to be spoon fed :( I'm quite new to this and this is for a client and I would really appreciate all the help here and really have to get this working right. Thanks again everyone - waiting for all your replies.
