ELECTRONIC TAG, READER, AND MANUFACTURING METHOD THEREOF

摘要

A reader reads electronic tag data and a CRC code from an electronic tag and detects whether the electronic tag data has been received correctly, by using the CRC code. The CRC code is generated from reader data and electronic tag data stored in the reader and an error detection is performed by using the reader data so that simultaneously with the error detection, it is possible to selectively read out only the electronic tag data from the electronic tag correlated with the reader data.
