ID INFORMATION NON-CONTACT COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an IC information non-contact communication system which can read ID information stored in a data carrier only with a specified scanner and can obtain high security. SOLUTION: A non-contact ID information communication system has a data carrier 1 storing ID information and a scanner which communicates with the data carrier 1 without contact and receives ID information transmitted from the data carrier 1. Collation data transmitted from the scanner and received by the data carrier 1 are collated with collation data stored in the data carrier 1. Then, ID information is transmitted from the data carrier 1 after collation data are matched. ID information can be read only by the specified scanner having collation data matched with collation data stored in the data carrier 1, ID information of the data carrier 1 is read by a non-specified scanner, so that illegal use can be prevented.
