ABSTRACT:
A portable electronic identification system comprised of an identifier preferably of credit card size, and a fixed position reader which couples to it over short distances by space transmitted signals. The identifier card is energized from and the resulting signals are synchronized and detected by the reader. The identifier uses one loop antenna to both receive and send all signals, and provisions are made to prevent interference of these functions. The use of multiple radio frequencies greatly increases the data rate. Data that is unique to the authorized bearer is recorded in the identifier to minimize the likelihood of fraudulent use.
