Can't you generate the swipe data from the other information you have, i.e. name, the card number, the expiration date, and the CVV2? ISO/IEC 7813 also specifies that there can be discretionary data but it seems it's unused, so what is the significance of swiping in addition to taking a picture and it seems also entering in the expiration and CVV (and number?) manually?
