Date Mar. 4, 1993.An apparatus for identifying coins uses inductive coupling of the coin with a pair of inductors. The apparatus includes a path for coins to be tested, first and second inductors for forming concurrent inductive couplings with the coin being tested, switches for energizing the inductors in specific manners so that a sequence of coin tests results, and a sensor for sensing the resultant inductive coupling for each of the tests in the sequence.</p> |
