20110234382 | COUPLED RADIO FREQUENCY IDENTIFICATION (RFID) AND BIOMETRIC 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. | 09-29-2011 |
20110057043 | RADIO FREQUENCY IDENTIFICATION (RFID) ANTENNA WITH TUNING STUBS FOR MOUNT ON METAL RFID TAG - A Radio Frequency Identification (RFID) device can comprise a dielectric separator and a RFID antenna with a RFID chip region. The antenna can have a main section and at least two tuning stubs that fold back from areas on the main section of the RFID antenna which are away from the RFID chip connection region back towards the RFID chip antenna region. The tuning stubs can be spaced away from the main section. | 03-10-2011 |
20100289626 | RADIO FREQUENCY IDENTIFICATION (RFID) ENABLED INVENTORY TRAY - A tool tray can comprise a body with tool shaped recesses. A Radio Frequency Identification (RFID) tag can be positioned in one of the recesses. The RFID tag can be such that when no tool is placed in the one of the recesses, the tag is not detectable at a reading distance; but, when a corresponding tool is placed into the one of the recesses, the RFID tag is detectable from a reading distance. | 11-18-2010 |
20100271180 | RADIO FREQUENCY IDENTIFICATION (RFID) CREDENTIAL FOR GUEST SERVICES - A Radio Frequency Identification Device (RFID) tag can be used to store a Hospitality Industry Organization ID of a customer. The RFID tag can be detected and then the Hospitality Industry Organization ID can be determined by using a device at a hospitality location to determine information about the customer to facilitate service for the consumer. | 10-28-2010 |
20090315686 | RFID TAG USING ENCRYPTED VALUE - 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. | 12-24-2009 |
20090256762 | RFID ANTENNA WITH QUARTER WAVELENGTH SHUNT - An RFID antenna can include a shunt across a connector region of a length in a range of 1/6 to 1/3 of the operating wavelength of the RFID antenna. This can improve the operating characteristics of the RFID antenna. | 10-15-2009 |
20090128417 | ELECTROLESS/ELECTROLYTIC SEED LAYER PROCESS - An electroless metallization catalyst layer can be formed in a RFID antenna pattern. A first metallic layer can be deposited over top of the electroless metallization catalyst layer. An electrical short layer connecting regions of the metallic layer can be formed. A portion of electrical short layer can be covered with a non-conductive layer. The first metallic layer can be electroplated with a second metallic layer. | 05-21-2009 |
20090128337 | RFID BASED KEYBOARD - 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. | 05-21-2009 |
20090128333 | RFID INVENTORY MONITOR - 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. | 05-21-2009 |
20090128295 | RFID BASED IDENTIFICATION DEVICE - 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. | 05-21-2009 |
20090096574 | RFID TAG USING ENCRYPTED PASSWORD PROTECTION - 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. | 04-16-2009 |
20080311704 | RADIO FREQUENCY IDENTIFICATION (RFID) TAG LAMINATION PROCESS USING LINER - 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. | 12-18-2008 |
