DATA TRANSFER SYSTEM FOR CURRENCY CASSETTES 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 (80) on which are mounted a RAM (136), a microprocessor (132) connected to the RAM (136), a photodiode (104) adapted to receive data from an LED (162) mounted on a second printed circuit board (54) secured to the cassette receiving compartment, an LED (106) adapted to transmit data to a photodiode (60) mounted on the second board (54), and a first circuit (138, 86) including a first coil (86) adapted to receive power from second circuit (108, 110, 112, 76) including a second coil (76) mounted on the second board (54). In operation, data is transferred between the RAM (136) and a microprocessor (79) external to the cassette by means of the cooperating photodiodes (104, 60) and LEDs (106, 62), with the first circuit (138, 86) serving to provide a dc power supply for the other components mounted on the board (80).
