Information processing apparatus

摘要

An information processing apparatus according to an embodiment includes a communication control unit controlling communication of a radio communication device with a data carrier transmitting a signal including communication distance information regarding a communication distance; an output variable control unit varying transmission output of the radio communication device; and a data carrier determination unit determining that the data carrier having a short communication distance is valid as the transmission output is large, and determining that the data carrier having a long communication distance is valid as the transmission output is small.

1. An information processing apparatus comprising:
a communication control unit controlling communication of a radio communication device with a data carrier, the data carrier transmitting to the information processing apparatus a signal including communication range information regarding a communication range of the data carrier; an output variable control unit varying transmission output of the radio communication device; a data carrier determination unit determining that when the transmission output is large, the data carrier whose communication range is shorter than a predetermined value is valid and the data carrier whose communication range is equal to or larger than the predetermined value is invalid and that when the transmission output is small, the data carrier whose communication range is larger than a specific value is valid and the data carrier whose communication range is equal to or smaller than the specific value is invalid; and an information processing unit processing information included in the signal received from the data carrier determined to be valid by the data carrier determination unit and not processing information included in the signal received from the data carrier determined to be invalid by the data carrier determination unit.
