Noncontact reader/writer, information communication system using the same, and management system using the same
First Claim
1. A noncontact reader/writer for plural kinds of noncontact information carriers comprising:
- a transmitter for sending a signal to each of the plural kinds of noncontact information carriers;
a receiver for receiving a signal from said each of the plural kinds of noncontact information carriers;
a memory for storing information on a kind of at least one of the plural kinds of the noncontact information carriers with which the noncontact reader/writer has communicated; and
a controller for determining, based upon the information, a priority order in a communication processing on a kind of noncontact information carrier, among the plural kinds of noncontact information carriers, and for carrying out the communication processing, and a priority memory for storing a priority table for showing a priority order on the kind of the plural kinds of noncontact information carriers with which the noncontact reader/writer communicates, wherein said memory includes a pointer memory to store a pointer value showing a specific priority order in the priority table, as the information; and
according to each kind of the plural kinds of noncontact information carriers with which the noncontact reader/writer has communicated, the controller determines the pointer value, and in next communication, the controller carries out communication processing, by determining the priority order in the communication processing based on the priority order shown by the pointer value.

Abstract
A noncontact reader/writer is disclosed which performs, at a high speed, a processing of communication, such as read or write, with a plurality of noncontact information carriers such as noncontact IC cards. A transmitting unit transmits signals, such as commands, to the respective kinds of noncontact information carriers. A memory stores information about at least one of the kinds of noncontact information carriers with which the noncontact reader/writer communicated. A control unit decides, based on the stored information, the priority of the kinds of noncontact information carries in the communication processing and performs a communication processing. The stored information includes the kinds of noncontact information carriers or the number of occurences of communication with the respective kinds of noncontact information carriers.
