Abstract
An RF identification system, including an identification tag having a unique RF signature, a source for generating RF energy, and a detector for reading the signature when the identification tag is illuminated the RF energy generated by the source. The identification tag includes a base formed from an electrically non-conductive material and metal particles distributed randomly in the base. Detected signatures may be stored for later comparison against detected signatures for identification purposes. Biometric data may be read and associated with corresponding signatures to identify and link objects with persons.
