Abstract:
A data reading system comprising:a data reader comprising a housing having a window, a photosensitive detector located within said housing, an optical collector for directing light on said photosensitive detector, processing circuitry connected to an output of said photosensitive detector, and an EAS antenna adapted to operate in a first frequency range suitable for electronic article surveillance (EAS) functionality, said EAS antenna having a characteristic impedance; a radio frequency identification (RFID) reader, said RFID reader having an antenna connector adapted to receive signals in a second frequency range different from the first frequency range; a first cable connection between said data reader and a host device; a second cable connection between said data reader and said antenna connector of said RFID reader, said second cable connection providing a signal path between said antenna and said RFID reader; and an impedance matching network connected to one end of said second cable connection, said impedance matching network having a characteristic impedance matching the characteristic impedance of said EAS antenna.
