Every merchant gateway should provide APIs to accept “card present” transactions in “ISO 7813 – Track 1” format. If your gateway does not provide this, ask them when they will add this support. If they have questions, you can refer them to us.
In some cases, to ensure compatibility, payments may need to be validated and converted to a format that is accepted by your gateway. This is done by calling a secure web service provided by Pocket Systems just before passing the payment to the gateway.
Example source code for implementing this service call is provided in several software languages. This compatibility step will eventually be eliminated as gateways, networks and card issuers implement full compatibility.
