Read-write processing device for RFID tag

摘要

A read-write processing device communicates with an RFID tag provided with a semiconductor memory to carry out read and write processes. A communication processing device executes communication processes with the RFID tag, exchanging commands and responses, and a data creating device creates safety data indicative of a margin of safety of communication based on communication results by the communication processing device. The created safety data are displayed or outputted to the outside by an output device.
