A radio frequency identfication (RFID) system is described, including a low frequency read-write device ( 1 B) comprising an antenna ( 2 B) connected to a transceiver ( 4 B), for receiving/transmitting low RF waves from/to an RFID tag ( 5 B), and a decoder ( 3 B) 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 ( 1 B) for processing digital data (dig-B). The RFID system further includes a high frequency read-write device ( 1 A), comprising an antenna ( 2 A) connected to a transceiver ( 4 A), for receiving/transmitting high RF waves from/to an RFID tag ( 5 A), and a decoder ( 3 A) 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 ( 1 B) 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 ).
