Looking for a dev who has previous experience writing code for Telium2 terminals, specifically iCT2xx terminals.
Need a quick proof of concept developed: computer sends command over USB to an iCT2xx device to request payment for x amount. Ideally, once payment card presented, the payment terminal responds with a SHA256 hash of the card number (PAN). Alternatively, payment terminal responds with the non-hashed full PAN.
Would require creating 1 or 2 small scripts:
(1) Script that resides on computer to trigger the USB command to payment terminal (asking for payment) and to print out either the card number hash or raw full number once returned.
(2) Script that resides on payment terminal to SHA256 hash the card number before returning it over USB to the script residing on the computer.
