ios usaepay magstripe credit card data, send for processing

Question

In my application I use online payment, for that i used PaySabar device (audio jack device) which reads magstrip data on credit card swipe.

I got credit data in encrypted format, all track1, track2 data are correct and perfect, but how to i send that data to USAePAY server. Please help.

Answer 1

I believe USAePay requires the encrypted data to be:

1. Encrypted with their public key
2. Formatted in a specific manner
3. Passed in magstripe or credit card number field

Because you are using their PaySaber hardware, see below for step 3.

USAePay Wiki - End To End Encryption:

If you are using idynamo library, here is what you need to do:

NSString *responseString = [mtSCRALib getResponseData];
NSData *responseData = [responseString dataUsingEncoding:NSASCIIStringEncoding];
NSString *encodedString = [NSString stringWithFormat:@"enc://%@", [^] [responseData base64Encoding]];

and then send encodedString to the gateway as MagStripe.
