RFID tag structure having anti-reuse function and manufacture method thereof

摘要

The present invention provides a RFID tag structure having anti-reuse function, comprising a substrate; a pattern formed on a surface of the substrate; and an adhesive layer provided on a surface of the pattern which is not in contact with the substrate, wherein the adhesive forces of the adhesive layer are stronger than the binding strengths generated between the pattern and the substrate, and the adhesive layer is capable of being adhered on an article to be adhered and a RFID tag is formed thereby; when the RFID tag is separated from the article to be adhered, the substrate is released from the article to be adhered, the pattern and the adhesive layer are still remained on the article to be adhered, thereby preventing the RFID tag from being reused and fulfilling the objective of anti-reuse and anti-counterfeit. The present invention also provides a manufacture method thereof.

主权项

1. A manufacture method of RFID tag structure having anti-reuse function, including steps of:
printing adopted ink containing catalyst on a substrate thereby forming a pattern; drying or baking said ink to cause said ink to react with said substrate and the binding strengths being generated thereby; immersing said substrate on which said ink printed in a solution containing metallic ions to cause said metal to be deposited on said ink and said pattern equipped with electric conductive function on said substrate; and thereafter, applying an adhesive layer having the adhesive forces on said pattern, and positioning said adhesive layer wherein said adhesive layer being separated from and not contacting said substrate, wherein said adhesive forces are stronger than said binding strengths.
