Contactless type communication tag, portable tag reader for verifying a genuine article, and method for providing information of whether an article is genuine or not
First Claim
1. A contactless communication tag that is attached to a product and provides product information, the contactless communication tag comprising:
- a contactless communication unit, which wirelessly exchanges data with a tag reader, creates a power source from a power signal received from the tag reader, and supplies the power source;
a storing unit in which the product information and encryption key related information are stored; and
an encryption unit, which encrypts the product information to be transmitted to the tag reader based on the encryption key related information.

Abstract
Provided are a contactless communication tag, a portable tag reader, and a method of providing genuineness of a product. The tag reader specifies an encryption key corresponding to an encryption key stored in the tag from its own plurality of encryption keys based on a signal received from the tag. The tag reader receives an encrypted product code or product information from the tag and decrypts the received product code or product code using an encryption key. Also, the tag reader outputs a result of decryption on a 7-segment display window, a plurality of color light emitting diodes (LED), and/or a liquid crystal display (LCD) window or as beep sounds or voices.
