Method and system for contactless transmissions using off-the-shelf devices

Abstract:

A method for secured receipt and usage of payment credentials using a commercial-off-the-shelf (COTS) device includes: storing, in the COTS device, a secure application program and cryptographic keys; establishing, by the program, a secure communication channel with a back-end system inaccessible by any application program or component in the COTS device; exchanging attestation data between the program and the back-end system using the communication channel; receiving payment credentials from a payment card by a near field communication (NFC) interface in the COTS device; transmitting the payment credentials to the program by the NFC interface; enciphering, by the program, the payment credentials; and transmitting, by the program of the COTS device, the enciphered payment credentials to the back-end system using the secure communication channel.
