  • Patent number: 7651025
    Abstract: An RFID system, which operates at different frequencies, for information interchange is provided. The system includes a user RFID module and a proprietor RFID module. The two RFID modules include a tag and a tag reader which operate at different frequencies, respectively. The frequency of the tag of the proprietor RFID module is the same as that of the tag reader of the user RFID module. According to the frequency, the data in the proprietor RFID module is able to be read by the tag reader of the user RFID module. The frequency of the tag reader of the proprietor RFID module is the same as that of the tag of the user RFID module. According to the frequency, the data in the user RFID module is able to be read by the tag reader of the proprietor RFID module.

  • Patent number: 7568211
    Abstract: The invention discloses a system and method to implement a business model for advertising revenue that allows advertising hosts to reliably detect registered audience members who respond to advertisements by coming into close physical proximity of designated locations, so that corresponding advertisers may be billed accordingly. A host system operated by the advertising hosts includes a data processing module, an electronic environment, advertisements, and a data communications network. The electronic environment presents content associated with that environment and the advertisements. Audience members who see the advertisements and respond by coming into close proximity to the designated locations associated with the advertisements are then detected by readers. An embodiment of the system and method utilizes RFID tags placed at the designated locations, and it utilizes RFID readers cared by audience members used to detect the tags when audience members come into close proximity of the tags.

  • Patent number: 7385512
    Abstract: A flexible radio frequency identification label and a method for fabricating the same are proposed. A first flexible protection layer is attached to a second flexible protection layer to form a closed space for receiving a radio frequency identification circuit. By such arrangement, a good flexibility can be provided by the flexible protection layers, and the closed space also enables the radio frequency identification circuit to be protected and isolated from the moisture in the outside environment, such that the circuit can be prevented from being oxidized and the service life of the product can be extended.
