Abstract: The disclosure relates to systems and techniques for reading optical codes, and more particularly to code reading systems with plural imaging or scanning modules pointed in various directions toward a target volume, which increase the likelihood that a code symbol on an arbitrarily oriented object in the target volume will be read. Other aspects of the invention relate to use and configuration of hand held readers, docking devices, operator side rails, arched tunnels and mirrors for increasing the coverage of the system. Additional aspects of the invention relate to components associated with point of sale installations or code reading terminals including integrated scales, input pads, system controls and displays.

Abstract: An RFID relay device for an RFID transponder and methods are provided for relaying an RFID signal. The RFID relay device comprises at least two antenna and a transmission line coupling the at least two antenna. In addition to the two antenna and the transmission line, the RFID relay device comprises an impedance adjusting circuit coupled to the transmission line and configured for coupling to the RFID transponder.
