Abstract: A device implementing an express credential transaction system includes at least one processor configured to receive an indication that a payment applet for a service provider has been provisioned on a secure element of the device with a first attribute indicating that the payment applet can be utilized for a transaction without authentication associated with the transaction. The processor is configured to set the first attribute of the payment applet to indicate that authentication is required to utilize the payment applet when another payment applet for the service provider provisioned on the secure element of the device has an attribute that indicates the other payment applet can be utilized for the transaction without user authentication. The at least one processor is configured to control whether the user authentication is requested when utilizing the payment applet or the other payment applet, respectively, in transactions.

Abstract: Techniques are disclosed relating to biometric authentication. In one embodiment, a computing device includes a controller circuit, a camera, and a secure circuit. The controller circuit is coupled to a button and detects when the button has been pressed. The camera captures a set of biometric data of a user. The secure circuit performs an authentication of the user by confirming that a notification identifying the button being pressed was received from the controller circuit and by comparing the set of biometric data with another set of biometric data for an authorized user of the computing device. In some embodiments, the controller circuit is configured to maintain a timestamp indicative of when the button has been pressed and usable by the secure circuit to confirm that the button is pressed within a threshold time period of the authentication being performed.
