ABSTRACT:
A memory of a data carrier attached to an article to be identified stores a classification code indicative of the data carrier's own communication protocol. Plural types of communication protocols are registered, in correspondence with the classification codes thereof, in the memory of a controller capable of communicating with the data carrier. Upon receiving a classification code transmitted by the data carrier, the controller selects from its memory a communication protocol indicated by the received classification code and then executes communication with the data carrier by using the selected communication protocol.
