摘要：
An RFID tag that is very effective in preventing fraud includes a base 105, an antenna pattern 102 provided on the base, a breakdown pattern 103 provided on the base, a circuit chip 101 connected to both the antenna pattern and the breakdown pattern, and a cover 106 that is bonded to the base in a strippable manner so as to cover the antenna pattern, the breakdown pattern and the circuit chip. On tampering with the tag, the cover is caused to come off from the base together with all or a part of the breakdown pattern 103. The breakdown pattern is transparent, or the cover conceals the remaining part of the breakdown pattern, if only part is removed, or the breakdown pattern has a specific part that produces predetermined electrical properties such as a resistance and the cover conceals the specific part. It is thus made difficult to recognise and repair the removal or destruction of the breakdown pattern.
