Fingerprint recognition control methods for payment and non-payment applications

[0008]In an exemplary embodiment, an electronic device is provided. The electronic device comprises a first memory unit for storing a non-payment application, a first processor, a fingerprint sensing unit and a security element. The security element is coupled to the fingerprint sensing unit, and comprises a second processor and a second memory unit for storing a payment application, first user fingerprint information and second user fingerprint information. When the second processor executes the payment application, the fingerprint sensing unit captures a fingerprint image of a user's finger and the second processor transmits the captured fingerprint image to the first processor via a secure channel. The first processor calculates biometric characteristics of the fingerprint image to generate to-be-recognized fingerprint information, and transmits the to-be-recognized fingerprint information to the second processor via the secure channel. The second processor further determines whether the to-be-recognized fingerprint information matches the second user fingerprint information. When the second processor determines that the to-be-recognized fingerprint information matches the second user fingerprint information, the second processor generates an authentication signal for a payment transaction.

However, the computation ability of the conventional security element is very limited.

If the fingerprint recognition required by the payment tra
