Abstract

A data transfer apparatus includes: a data transfer machine with sufficient memory to store the data to be transferred in a transfer data address; and a receiver which receives a signal from the data transfer machine, in the meantime, the receiver will write the data to be transferred into a transfer data position, if the data to be transferred differs from the data stored, the data transfer machine will transmit a response, if all data agrees, the tag antenna will not transmit such a response.
