A mobile terminal includes a contactless communication unit configured to conduct contactless communication with an external communication apparatus, a plurality of memory units configured to store information to be transmitted to the communication apparatus, and a controller configured to control communication with the communication apparatus and set a priority order for the plurality of memory units when transmitting information from the plurality of memory units to the communication apparatus. The controller sets the priority order depending on the current time.

Mobile terminal, information processing method, and computer program

In one example embodiment, an information processing apparatus determines whether a target ID is a unique ID or a partial randomization ID that includes a first part being replaced by a different number and a second part being generated based on the unique ID. In response to the target ID being the partial randomization ID, the information processing apparatus generates an access key based on the second part of the partial randomization ID and a key. The information processing apparatus executes a mutual authentication process using the generated access key.
