Abstract

PROBLEM TO BE SOLVED: To provide an inspection system using conformability RFID tags capable of discriminating a product from non-conformity products or products which have not yet been inspected by a simple and low cost system by sticking a conformability RFID tag to the product which has passed inspection so that only conformity products are packed or shipped before they are packed and shipped. SOLUTION: In this inspection system using RFID tags as a conformity inspection seal, a pair of dielectric parent-antenna patterns are attached to a product or the package of the product beforehand. When the product is regarded as a conformity product as a result of inspection, at least an IC chip and a pair of sub-antenna patterns of an IC chip label, which has a pair of sub-antenna patterns connected to the IC chip and became a tack label with pressure sensitive adhesive on the faces of the antenna patterns, are stuck to places opposing to a pair of the parent antenna patterns, which are provided to the product or the package of the product beforehand so as to function as FRID tags.

複数の製品が同一梱包されていても、複数の適合品を正確に判定することで、一つ一つ確認するために開梱しなくて良い。 Even if a plurality of products are the same packing, by accurately determine a plurality of compliant products may not unpacking to one single check.

【0030】製造工程の工程検査の結果を、工程毎にデータを追記して行けば、工程管理ができる。 [0030] The results of the process inspection of the manufacturing process, should I append the data for each process, it is process management. また、出荷検査での試験成績表などデータを記録して出荷すれば、 Also, if shipping records data such as test results table in shipment inspection,
製品の受け取り先でも、受け入れや受入検査に利用することもできる。 Also a product of the receiving destination, can also be used for acceptance or acceptance inspection.
