  • Fraud-resistant electronic identification device
    Patent number: 5588234
    Abstract: The identification device for animals or articles is internally provided with an electronic identification circuit enabling automatic remote detection of the code of the identification device. The identification device comprises a member comprising the identification circuit and a member serving for attachment. The member comprising the identification circuit is made of hard material. The external shape of this member, starting from a base which in operation abuts against the article or the animal, narrows substantially taperingly and smoothly to an end which in operation is located remote from the article or animal, so that this member cannot be gripped by another animal between its teeth or be caught on obstacles or other objects.
