<p>An embeddable, non-invasively and non-destructivelly measurable identification marker (10) is described which can be read out despite a cover layer (2) which substantially reduces radio frequency and mechanical access. The marker (10) can store data in excess of 16 bit. The marker (10) is preferably remotely readable, is not erasable by electromagnetic radiation, is visually camouflageable and its stored information survives exposure to high temperatures which makes it suitable for use in safety critical applications. A system of detection of the identification marker (10) is also described.</p> |
