US10817878B2 Systems and methods for verifying users, in connection with transactions using payment devices
Systems and methods for verifying users in connection with transactions using payment devices are disclosed. One exemplary method generally includes receiving a select command for an AID associated with a payment application from a terminal and, in response, initiating by a security chip of a payment device, a timer after power-up of the security chip by the terminal. The method also includes capturing a biometric of a user, at a biometric sensor, according to the payment application, and verifying, by the security chip, the captured biometric based on reference biometric data. The method further includes, when the timer is unexpired and the captured biometric is verified, appending a first value to a CVR and returning a first AFL to the terminal, and when the timer is expired, appending a different value to the CVR and returning a different AFL to the terminal.
