摘要: A token and photo-detector circuitry in an electronic device used for supplying electrical power to an external appliance for an amount of time represented on the token. The token contains encoded information in a base numbering system in several regions of the token and this information is read by the circuitry to represent a time value whereby the circuit relays power to the appliance for an equivalent length of time. Several tokens may be deposited into the device in any orientation so as to accumulate time for use of the appliance. The device is programmable and can communicate with the user/operator with the appropriate hardware additions.
