1. An integrated RFID reader comprising:
- a first transceiver operatively coupled to a first antenna for communicating at a first frequency;
a second transceiver operatively coupled to a second antenna for communicating at a second frequency; and
a firmware module in communication with the first transceiver and the second transceiver for analyzing data acquired by the first transceiver and the second transceiver.

Abstract
The present invention discloses an integrated RFID reader (205) that combines active and passive RFID technology to enable automatic identification for any asset equipped with an active or passive RFID tag. The integrated RFID reader uses either a single antenna or dual antennas (225, 230) and two transceivers (210, 215) with a firmware module (220) to read and receive data from both active and passive tags. Similarly, a method for exchanging data between active tags and passive tags is also disclosed (315).
