Electronic device for contactless payment

Abstract

An electronic device and an authentication method thereof are disclosed herein. The electronic device includes a sensor module, a network module, at least one processor and a non-transitory computer-readable medium. The non-transitory computer-readable medium stores a first prestored biometric signature and computer-executable instructions to be executed by the at least one processor for performing the authentication method, in which the first prestored biometric signature is verified and issued by a first payment service. The authentication method includes the following steps: detecting a first biometric signature by the sensor module; determining whether the first biometric signature matches the first prestored biometric signature; authenticating the first payment service if the first biometric signature is determined to match the first prestored biometric signature; and transmitting or receiving data corresponding to the first payment service by the network module.
