Abstract:
A method of constructing an RFID unit can include using a protective layer to hold an integrated circuit chip module to a substrate layer with an antenna unit while a conductive adhesive has not yet fully set.
Abstract:
An RFID securitization piece can comprise a housing. An RFID tag in the housing can include an RFID chip and RFID antenna. The RFID securitization piece is attachable to an object such that when the RFID securitization piece is removed from the object the RFID tag is damaged. RFID interrogations will then indicate that the RFID securitization piece has been removed from the object.
Abstract:
An antenna web can include an RFID antenna on a first side of a substrate. An adhesive can be laminated on a second side of the substrate. The antenna web can then be cut into individual segments for use in constructing an RFID label.
Abstract:
A two resist layer process allows a seed layer to be used to electroplate a conductive layer of an element in a way that a portion of the seed layer can be removed.

Abstract:
A RFID-based identification device can comprise first and second RFID antennas. When first and second RFID antennas are in a first arrangement, the resonant frequencies of the antennas can be away from an interrogation frequency such that no identification information is transferred. When the first and second RFID antennas are in a second arrangement, the resonant frequency of the identification device shifts such that identification information, including biometric data, is transferred.
Abstract:
A permanent ID can be read off of an RFID chip of an RFID tag. The permanent ID can be combined with a seed value to form a combined value. The combined value can be encrypted to form an encrypted value. This encrypted value can be stored on the RFID chip. Later, the RFID tag can be validated using the encryption value.
Abstract:
A game can comprise a board with multiple RFID antennas and a game piece with a RFID antenna. When one of the multiple RFID antennas is adjacent to the RFID antenna in the game piece, the response characteristics of these RFID antennas can change so that the position of the game piece can be determined.
Abstract:
A metalized circuit suitable for application as a radio frequency antenna is produced by forming an antenna coil pattern on a flexible substrate. The antenna coil pattern is formed using a conductive ink which is patterned on the substrate. The conductive ink is cured and an electrical-short layer is formed across the coils of the conductive ink pattern. An insulating layer is formed over top of the electrical-short layer, a metal layer electroplated on top of the conductive layer, and then the electrical-short layer is removed. The use of the electrical-short layer during the electroplating allows for the voltage at the different points on the conductive ink layer to be relatively similar, so that a uniform electroplate layer is formed on top of the conductive ink layer. This results in a better quality radio frequency antenna at a reduced cost.
