A wearable RFID device is configured with a geometry and materials that allow an HF RFID system and a UHF RFID system to operate in close proximity to a human body and to each other with minimal impact on performance. An RFID device may have a three-dimensional, multi-planar UHF antenna incorporated into a dielectric core with an HF antenna, or a single-plane UHF antenna separated from an HF antenna by a rigid spacer. A conductive metal backplane is disposed adjacent the wearable RFID device to improve antenna performance when disposed in close proximity to an absorbing body, such as a human being.

Combined HF and UHF RFID device

A Radio Frequency Identification (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.

Coupled radio frequency identification (RFID) and biometric device

An RFID keyboard comprising a base with a first antenna and; keys with secondary antennas wherein a key is normally in a first position such that the resonant frequency is away from an interrogation frequency and no signal for the key is detected and wherein when the key is depressed, the secondary antenna for the key and the first antenna become adjacent such that the resonant frequency shifts such that information identifying the key is transferred.

A case for containing objects can include a Radio Frequency Identification (RFID) Reader antenna to detect any RFID tags placed within the case. The RFID antenna can operably connect with external RFID Reader components to detect RFID tags in the case. Alternately, a case can also include a passive RFID antenna to couple with any RFID tags in the case.

Inventory system for RFID tagged objects

Moving a mobile RFID reader with an area in a systemic manner to do non-inventory tasks, while doing the non-inventory tasks, integrating RFID tags associated with inventory, and updating a database with the inventory information obtained from the RFID tags.

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.

Radio frequency identification (RFID) tag lamination process

A RFID-based identification device comprising a first RFID antenna; and a second RFID antenna, wherein the first and second RFID antennas are in a first arrangement, the resonant frequencies of the antennas are away from an interrogation frequency such that no identification information is transferred, and wherein when the first and second RFID antennas are in a second arrangement, the resonant frequency of the identification device shifts such that identification information is transferred.

RFID based identification device

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.

Game system using RFID tags

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.

Radio frequency identification (RFID) tag lamination process using liner

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.

Method for forming radio frequency antenna

An RFID chip can have an RFID circuit having first and second initial bond pads and conductive paths on the RFID chip connecting the first and second bond pads to the different sides of the chip. The conductive paths including a first side connector on a first side of the chip electrically connected to the first bond pad and a second side connector on a second side of the chip connected to the second bond pad. The first and second side connectors can cover at least half of the first and second side length respectively.

Side connectors for RFID chip

A sensor can detect the presence of fluid by the changing of the response characteristics of an RLC circuit. A window in the sensor is used to position a short caused by the fluid.

Radio frequency identification sensor for fluid level

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.
