Abstract
A data transfer system includes a currency cassette adapted to be inserted in a cassette receiving compartment of a cash dispenser mechanism, the cassette having a first printed circuit board on which are mounted a RAM, a microprocessor connected to the RAM, a photodiode adapted to receive data from an LED mounted on a second printed circuit board secured to the cassette receiving compartment, and LED adapted to transmit data to a photodiode mounted on the second board, and a first circuit including a first coil adapted to receive power from second circuit including a second coil mounted on the second board. In operation, data is transferred between the RAM and a microprocessor external to the cassette by means of the cooperating photodiodes and LEDs, with the first circuit serving to provide a dc power supply for the other components mounted on the board.
