Abstract
A data reading system includes a dual ended cable for connecting an electronic article surveillance (EAS) antenna located on a data reader with a separate radio frequency identification (RFID) reading device. The dual ended cable has different termination impedances at either end, and has an impedance matching network at one end. The impedance matching network matches the impedance of the EAS antenna to the RFID reading device, thereby eliminating signal reflection and enabling the data reader to be used with the RFID reading equipment.
