1. A method of adjusting a transmission strength emitted by an RFID reader, the method comprising:
- scanning, by the RFID reader, a space for predetermined period of time at a first power level;
storing, in memory of the RFID reader, a first location of as a point of origin;
changing, by the RFID reader, the power level of the RFID reader to a second power level based on a distance of the RFID reader from the point of origin after the RFID reader is moved from the point of origin; and
scanning, by the RFID reader, the space for predetermined period of time at a 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.

6. 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 wherein the signal of decodable indicia 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, identifying, as a point of origin, a first location associated with the area; responsive to moving the RFID reader relative to the first location, determining, based on data received from a motion sensing device, a distance of the RFID reader from the point of origin; and adjusting a power level of the RFID reader relative to the determined distance of the RFID reader relative to the point of origin. - View Dependent Claims (7, 8, 9, 10, 11)

12. An apparatus comprising:
-
a scanning device that scans a signal of decodable indicia on an area associated with a physical object, an RFID reader transmitting at a power level; a motion sensing device; wherein responsive to scanning the signal of decodable indicia and responsive to the RFID reader being proximate to the area of the physical object, a point of origin is identified with a first location associated with the area; wherein, in response to moving the RFID reader relative to the first location and based on data received from a motion sensing device, a distance of the RFID reader from the point of origin is determined; and wherein, in response to determining the distance, the power level of the RFID reader is adjusted relative to the distance. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
