US Patent 12026705 System and method for payments using biometric authentication

In order to validate a user to facilitate conducting a high-valued financial transaction via wireless communication between an electronic device (such as a smartphone) and another electronic device (such as a point-of-sale terminal), the electronic device may authenticate the user prior to the onset of the high-valued financial transaction. In particular, a secure enclave processor in a processor may provide local validation information that is specific to the electronic device to a secure element in the electronic device when received local authentication information that is specific to the electronic device (such as a biometric identifier of the user) matches stored authentication information. Moreover, an authentication applet in the secure element may provide the local validation information to an activated payment applet in the secure element. This may enable the payment applet to conduct the high-valued financial transaction via wireless communication, such as near-field communication.
