<p>PROBLEM TO BE SOLVED: To accurately read and write data of a radio data carrier attached to a registered mail, etc., stored in a carrier case. SOLUTION: The radio data carrier 7 storing an ID number is attached to the registered mail 6, information such as a sender and an addressee is registered to an acceptance office server 15 corresponding to the ID number, and the similar data is transmitted to a relay office server 13 and a delivery office server 16. The relay office and the delivery office read the ID number of the radio data carrier 7 to transmit the arrival information to each server and control the registered mail. In the relay office and the delivery office, the data of the radio data carrier 7 attached to the registered mail 6 is read and written from outside the carrier case 1. Therefore, this system is so constituted that an antenna 5 is provided in a partition board 4 of the carrier case 1 and the electromagnetic wave from an antenna 8 of an RFI question device 12 is relayed by the antenna 5 of the partition board 4 so that the data in the radio data carrier 7 is read and written.</p> |
