Abstract

A system and method of adjusting the transmission strength emitted by an integrated RFID reading device by an EIR terminal. The EIR terminal scans a signal of decodable indicia, locates the decodable indicia within the signal, decodes the decodable indicia into a decoded message, which is an identifier for said physical object. The EIR terminal then makes contact with the physical object and stores the location of this contact as a point of origin and then, moves through three dimensional and receives values from its motion sensing device representing the location of said EIR terminal in three dimensional space relative to the point of origin. Then, the EIR terminal determines the distance of the RFID reading device from the point of origin and adjusts the power level of said RFID reading device relative to this distance.

Dependent claims

An encoded information reading (EIR) terminal comprising:

a microprocessor;
a scanning device, said scanning device configured to scan a signal of decodable indicia on a pre-defined area of a physical object, said scanning device further configured to locate said decodable indicia within said signal of decodable indicia, said scanning device further configured to decode said decodable indicia into a decoded message, and said scanning device further configured to output said decoded message, wherein said decoded message contains information describing said physical object;
an RFID reading device, said RFID reading device transmitting at a power level;
a memory;
a communication interface, said communication interface configured to receive said decoded message, said communication interface further configured to display said information describing said physical object;
a motion sensing device;
wherein said EIR terminal is configured, responsive to making mechanical contact with said pre-defined area of said physical object, to store in said memory a point of origin of said EIR terminal described by information in the decoded message at said pre-defined area of said physical object;
wherein responsive to moving said EIR terminal through three dimensional space relative to said physical object, said EIR terminal is further configured to receive values from said motion sensing device representing the movement of said EIR terminal in three dimensional space relative to said point of origin;
wherein said EIR terminal is configured, responsive to receiving said point of origin and said values from said motion sensing device to determine a distance of said RFID reading device from said point of origin;
and
wherein said EIR terminal is configured to adjust said power level of said RFID reading device relative to said distance.
