1. A method of adjusting a transmission strength emitted by a reader, the method comprising:
- scanning, an item by the reader, at a first location as a point of origin at a first power level;
storing the first location in memory of the reader; and
determining a distance of a second location of the reader relative to the first location based on the data received from a motion sensor;
changing the power level of the reader to a second power level based on the distance, which is determined based on the data received from the motion sensor; and
scanning at the second power level.

Abstract
A system and method of adjusting the transmission strength emitted by an integrated RFID reader. The system may stores the location of the RFID when moved proximate to an object as a point of origin. When the RFID reader moves relative to the point of origin, the system may determine the distance of the RFID reader from the point of origin and may adjust the power level of the RFID reader relative to this distance.

10. A method of adjusting the transmission strength emitted by an integrated RFID reader, the method comprising:
-
scanning, by the RFID reader, a signal of decodable indicia that is located on or proximate to an area of a physical object; responsive to scanning the signal of decodable indicia and responsive to the RFID reader being proximate to the area of the physical object based on data received from a motion sensor, identifying a first location of the RFID reader; responsive to moving the RFID reader relative to the first location, determining a distance, based on the data received from the motion sensor, of the RFID reader from the first location; and adjusting a power level of the RFID reader relative to the distance, which is determined based on the data received from the motion sensor, of the RFID reader relative to the first location. - View Dependent Claims (11, 12, 13, 14)

15. An apparatus comprising:
-
a scanning device that scans a signal of decodable indicia on an area associated with a physical object; a reader transmitting at a power level; and a motion sensor, wherein responsive to scanning the signal of decodable indicia and responsive to the reader being proximate to the area of the physical object and responsive to the RFID reader being proximate to the area of the physical object based on data received from a motion sensor, a first location of the reader is identified, wherein, in response to moving the reader relative to the first location, a distance, based on the data received from the motion sensor, of the reader from the first location is determined, and wherein, in response to determining the distance based on the data received from the motion sensor, the power level of the reader is adjusted relative to the distance. - View Dependent Claims (16, 17, 18, 19, 20)
