Livestock tagging is accomplished by using a "smart card" (2) electronic tag, encasing it in a bio-compatible envelope (4) and anchoring it to the tissue into which it is implanted. The anchoring means can take several forms such as an apertured member (10, 12) which can be separated from the envelope by tearing along a line of perforations (6, 8) or an outercasing (42) of open celled elastomer to which the tissue can become anchored. The outer casing (42) can be split to remove the "smart card" (40). The electronic tag is programmed with the life history of the animal to which it is implanted by successive remotely effected updates. In addition both the "smart card" and the anchor contain identical identifying codes to enable a readout from any "smart card" to be associated with the animal from which it came. |
