1. An electronic device having a radio frequency identification (RFID) tag comprising:
- an RFID tag circuit including;
an input/output (I/O) interface;
a memory for storing data;
a first path-controlling circuit for receiving a first signal via the I/O interface, receiving a second signal in a wireless manner, and outputting one of the first and second signals;
a baseband circuit coupled to the first path-controlling circuit and the memory for processing signals outputted by the first path-controlling circuit, accessing data stored in the memory, and outputting an output signal; and
a second path-controlling circuit coupled to the baseband circuit for outputting signals outputted by the baseband circuit via the I/O interface or in a wireless manner; and
an integrated circuit coupled to the I/O interface for transmitting signals with the RFID tag circuit.

Abstract
An RFID tag is integrated with a processor of an electronic product for anti-theft purpose. The RFID tag receives an enable mark when the electronic product is checked out at a point of sale. Only when the processor receives the enable mark from the RFID tag can the start-up sequence of the electronic product be executed. An RFID tag is integrated with a sensor of an electronic product for data transmission purpose. Data measured by the sensor can be stored in the memory of the RFID tag and outputted via the antenna of the RFID tag.
