barcode
I'm writing some attendance software. Each member will have an ID card with a barcode which they will use to sign in to events. How long should the barcode field be in my database? I'd like to accept Code 39 and Code 128 barcodes. I know these are variable length codes, so what should I set the max length to?
Thanks!
EDIT: My clients will be using a variety of third-party barcode printing tools.
