Abstract

A communication device includes a first processing unit that detects a target and receives a first command for activating an interface upon a detection of the target. The communication device also includes a second processing unit that exchanges data with the target through the first processing unit. Further, the communication device includes an interface between the first processing unit and the second processing unit. The first processing unit selects a predetermined interface level from among a plurality of interface levels based on the first command and exchanges data with the second processing unit based on the predetermined interface level.
