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.

Abstract: Provided are a payment card, system and method for storing and reading tokenized payment account information from a payment card. In an exemplary embodiment, a payment card may include a substrate forming a body of the payment card, and an electronic chip attached to or included in the substrate. According to various exemplary embodiments, the electronic chip may include a storage storing tokenized payment account information corresponding to a payment account linked to the payment card. The electronic chip may be read by a payment terminal and may provide the tokenized payment information to the payment terminal during reading.

Abstract: A method for authentication facilitated via a trusted execution environment includes: reading payment credentials in a first application program stored in a first memory area of a computing device; transmitting an authentication request to a second application program stored in a trusted execution environment of the computing device separate from the first memory area; displaying a prompt for authentication data based on an instruction supplied by the second application program; receiving authentication data; transmitting the received authentication data to an external computing device; receiving, by the second application program of the computing device, an authentication result from the external computing device; and transmitting, by the second application program of the computing device, the authentication result to the first application program in response to the authentication request.
