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

Combined low and high frequency RFID system

The invention relates to a radio frequency (RF) system and method for improving the detection efficiency of an identification system including a transponder and a reader. The system () comprises an interrogator reader device () having an interrogator coil antenna () and a transponder () having a transponder coil antenna () and a microchip () Advantageously, the interrogator reader device () comprises a detection portion () including a sensitive signal gain detector (SSGN) for detecting just the presence of the transponder coil antenna () in case of misplacement of the transponder or broken link between the transponder coil antenna () and the microchip (). The invention allows remedying to those potentially dangerous situations that might lead to a misdetection of the transponder ().
