  • Patent number: 9875628
    Abstract: A disposable electrically conductive band for a re-usable RFID tag having an RFID tag holder, an electrical continuity contact within a loop on an end of the band, an electrically conductive landing area on a tongue of the band, the tongue being insertable through the loop to secure the band around a body to be monitored by an RFID system, the tongue thereby engaging a portion of the landing area with the electrical continuity contact. The conductive landing area has a series of electrical continuity dimples in each of which there is an electrical contact to an electrical pathway around the electrically conductive band. The RFID tag transmits an alarm to the monitoring agency whenever the band has been tampered with, severed, or otherwise circumvented.
    Type: Grant

  • Patent number: 8552866
    Abstract: The invention provides an RFID tag with means for determining when such tag has been tampered and means for securing the tag to an object. The tag may use an optical or infrared transmitter/receiver pair for detecting active tag removal from the object to which it is attached; and a method of attaching the tag holder to rounded objects regardless of object diameter while still preserving tamper capability of the active tag. Alternatively the tag may use an infrared radiation sensor to determine a change infrared radiation that occurs when the tag is removed from a person, and a light sensor to determine when tag has been tampered.
