I am using NSUrlConnection asyncronous request to transmit credit card information to a secure third party server.

I do the following:

1. I get the credit card number, cvv, etc from the uitextfields.

2. Encode the credit card information into a json format. Set as httpd body of the nsurlconnection request as follows:

   NSURL * url = [[NSURL URLWithString: "https://www.example.com"];

   NSMutableURLRequest * request = [[NSMutableURLRequest alloc] initWithURL: url];

   [request setHTTPMethod: @"POST"]; [request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

   [request setHTTPBody: [NSJSONSerialization dataWithJSONObject: params options: kNilOptions error: &parseError]];

3. Send this information via asynchronous request to a secure third party server:

   [NSURLConnection sendAsynchronousRequest:request queue: queue completionHandler:^(NSURLResponse *response, NSData *data, NSError * requestError) {

What should I be considering to send user credit card information to a third party server using nsurlconnection asynchronous request?
