Dear Dave Bush, I am not sure if this can be possible since the payment systemsare meant to detect an EMV transaction, so what you want to do is emulate a payment method with the "badge" of the student, worker, whatever your access is for and emulate a EMV transaction and use this payment method to send the information ? I am not sure if this is possible since it is done for EMV compliant transactions. I would recommend check with the apple team or community to see if this is feasible or not using that phone.
