Abstract: The present invention includes a driverless data transfer device and method for accessing and downloading item data from an item storage unit associated with an item. The driverless data transfer device includes, inter alia, a data downloading unit configured to download the item data, an interface unit for transferring the downloaded data to an item checking unit via a communications bus, and a decoder configured to decode said stored data to conform to data processing requirements of the item checking unit.

Abstract: An Electronic Article Surveillance (EAS) tag is removably mounted on a shaft of an eyeglasses temple to be protected. The EAS tag includes an elongated hollow arm member in which an EAS marker is stored. The EAS tag also includes a shaft holder member. The shaft holder member has several pairs of oppositely disposed openings on the circumference thereof to enable the holding of the eyeglasses having shafts with varied cross sections and widths. The arm member and the shaft holder member are coupled. A locking screw extending vertically through the front part of the elongated arm member right above the shaft holder is adapted to lock the shaft inserted through a selected pair of openings to the shaft holder. The locking screw has a special pattern on a head thereof. Locking or unlocking the shaft is accomplished by use of a special tool.

Abstract: A re-printable RFID hard tag for transferring stored data and which includes a RFID tag and a re-printable surface layer. The re-printable surface layer is adapted for reprinting by erasable ink.

Abstract: The invention relates to an event driven content switching technology in a passive, batteryless radio frequency identification (RFID) tag. The RFID tag device monitors the occurence of an external event such as a change in the environment. The switching of the context of the tag is effected by sensors incorporated in the tag. An external event triggers the switch. An RFID reader may subsequently read out the occurrence of the event due to the switch change. Different alignments of the switch could bring about the closing or opening of specific electronic circuits within the RFID tag that effect the storing of information in a selected memory, or changing the ID transmitted by the tag. In a particular embodiment this latter is accomplished by shorting one or the other of two RFID tag antennas. When one antenna is shorted, the second tag's ID is sent, and vice versa.
