1. A wireless communication system, comprising:
- an electronic device that operates in a low power sleep mode; and
a radio frequency identification tag that generates an output signal after said radio frequency identification tag is read, wherein said output signal triggers said electronic device to awaken from said low power sleep mode.

Abstract
A system and method for enabling interrupts for RFID tags. An RFID tag is provided with an output signal that can notify another chip in a system, or another function within the same IC, that a read of the RFID'"'"'s information has taken place. In one embodiment, the output signal would awaken a microcontroller from a low power sleep mode. The awakened microcontroller can be designed to perform a higher-level function than that supported by the RFID tag.
