ABSTRACT:
A radio frequency identification (RFID) system is described, including a low frequency read-write device (1B) comprising an antenna (2B) connected to a transceiver (4B), for receiving/transmitting low RF waves from/to an RFID tag (5B), and a decoder (3B) for decoding said low RF waves into digital data (dig-B); an host computer (20) is intended to be connected to the low frequency read-write device (1B) for processing digital data (dig-B). The RFID system further includes a high frequency read-write device (1A), comprising an antenna (2A) connected to a transceiver (4A), for receiving/transmitting high RF waves from/to an RFID tag (5A), and a decoder (3A) for decoding said high RF waves into digital data (dig-A); the high frequency read-write device is connected to a low frequency read-write device (1B) and to an host computer (20) respectively through a driver connection (22) and an host connection (21). A bundle interface (ITF), receives digital data (dig-A, dig-B) through the driver connection (22) while a flow controller (SW) drives the flow of such digital data (dig-A, dig-B) through host connection (21) and towards the host computer (20).
