An interactive wireless fingerprint recognition system utilizes fingerprint recognition to promote the convenience of use and the security of wireless controlling an external target at a remote site. A piezoelectric switch unit is utilized to trigger a wireless transmission device for capturing and characterizing the fingerprint image of the user. Next, the fingerprint image is packed into a data packet with a data packet format compatible with a Self-described Protocol with Variable Length (SPVL). The data packet is transmitted to a wireless reception device by the wireless transmission unit. After being decoded, the data are compared with the embedded fingerprint data of the user. Next, a control signal is sent out from an external target interface unit to make the back-end external target to execute the required functional operation, and the execution result is also sent back actively or passively to the wireless transmission device immediately or a periodically.
