Abstract
The method, terminal and computer program product determine the context of the mobile terminal associated with the RFID reader and adjusts the power consumption of the RFID reader based upon the determined context relative to at least one previous context determination. To adjust the power consumption, the frequency at which the RFID reader is actuated may be altered. Thus, the power consumption of the RFID reader may be reduced when no change in the context of the mobile terminal is determined and/or may be increased when a change in the context of the mobile terminal is determined. Due to the adjustment of power consumption by RFID readers, power is conserved in the mobile terminals associated with RFID readers, which permits the mobile terminals and RFID readers to operate longer without requiring charging or replacement of the power supply.
