Abstract
A system and method is provided for the identification and authentication of precious metals and small jewelry. The system can include an embedded RFID tag, RFID tag reader and reader based unit (wired or wireless), and a basic tag information system for tag capture, look-up and display. The RFID tag can be embedded in absorbing dielectric medium inside epoxy in a tiny cavity placed in the metal or jewelry. A thin layer of epoxy placed over the tag can ensure that the tag will not be damaged from rubbing against skin, abrasion or chemicals while still allowing the desired electromagnetic properties (antenna and the circuitry performance). The RFID tag information can be transferred to a computer through the reader, and can be matched with preprogrammed information in a database.
