Abstract:
A user signs into an application via a user computing device at a merchant system location. The user computing device receives an identifier from a beacon device at the location to transmit to an account management system. The account management system transmits facial templates to the merchant camera device for users who are signed in to the application in range of the merchant beacon device. The user approaches a point of sale device to purchase a restricted product or service. The merchant camera device compares a captured facial image against the received facial templates to identify the user. A merchant POS device operator, after determining that the user is eligible for the restricted product or service based on account information of the user, selects a payment account of the user. The merchant POS device transmits transaction details to the account management system, which processes the transaction with an issuer system.
