RADIO TAG PROCESSING DEVICE, RADIO TAG PROCESSING SYSTEM, AND RADIO TAG

摘要

A radio tag processing device improves the convenience of the user relating to the contents of information in a radio tag circuit element and the contents to be printed on a reversible printing area. The radio tag processing device includes a loop antenna (130) for transmitting/receiving information by radio to/from a radio tag circuit element (To) composed of an IC circuit unit (150) having addresses and a tag antenna (151) for transmitting/receiving information, an erasing thermal head (120) for substantially erasing unupdated characters (R) printed on a reversible printing area (S) of an IC card (200) having the radio tag circuit element (To) and the reversible printing area (S), a forming thermal head (120) for forming characters (R) representing the content corresponding to updated data on the reversible printing area (S), and a control circuit (140) for substantially holding information stored at predetermined addresses and writing corresponding information at the other addresses via the loop antenna (130).
