Each utility user is provided with a control device 19 (only one of which is shown) via which the utility user is connected to different utility networks such as, in the example illustrated, electricity network via connection telephone network via connection 11.2, and to a cable television network via a connection 11.3. The term utility user is intended to denote, for example, a domestic premises which is connected to the various utility networks.
BAD ORIGINAL The control device 10 comprises a circuit breaker 11.11 for interrupting the provision of electricity to the user, a suitable relay 11.21 for interrupting the telephone service, and a suitable relay 11.31 for interrupting the cable television service. The control device further comprises metering means for metering the consumption of electricity, metering means % for metering the use of telephone service, and metering means Mc for metering the use of cable television service. The metering means metering the use of telephone service may include a detector (not shown) for detecting when an outgoing call is answered from which a metering period can automatically be determined. In a simplified form it may consist simply of a timing device for determining the duration of connection to the telephone network. The metering means *1c for metering the use of cable television may comprise a timing device (also not shown) for determining the duration of connection to the cable television network. The control device may be provided with a real-time clock (RTC) 23 in which event any o* the metering means may be associated with the real-time clock so that the basis of metering the use of the respective utility can be varied depending on the date and time of use.
AP Ο Ο Ο 3 1 6 The control device 10 further comprises microprocessor based circuitry 30 which is capable of individually accepting a credit for the supply of the various utilities, and is operative in response to the various metering means Ma to Mc to reduce the credits according to the amount of corresponding utility used by the user. The microprocessor based circuitry is further operative to trip the circuit breaker 11.1 when the amount of electricity credited has been used, to open the relay 11.21 when the amount of telephone service credited has been used up, and to open the relay 11.31 when the amount of cable television service credited has been used up.
To enable the microprocessor based circuitry 30 to be credited for the provision of a particular utility the control device 13 further comprises a key-pad 12 and a decrypter 14. An encrypted payment code is keyed manually into the key-pad 12, decrypted by the decrypter 14, and, provided certain conditions are met (as described hereinafter) one of the utility credit memory means in the form of registers 30.1 to 30.3 incremented, the increment representing a credit for the supply of the amount of a utility paid fo»·.

The encrypted payment code issued by the vending station can now be entered manually via the key-pad 12 into the control device IT. The decrypter 1* of the control device then operates to decrypt the encrypted payment code, whereupon the control device extracts the device identity code, the transaction code, the utility code, and the amount code from the decrypted payment code.
The microprocessor based circuitry 30 of the control device 10 includes a memory device 30.5 which keeps a record of the transaction codes of previous payment codes accepted by the control device.
Once the device identity code and the transaction code have been extracted from the decrypted code, the control device verifies the device identity code and the transaction code. If the result of the verification is that the extracted device identity code does not match the device identity code of the device in question stored in register 30.4, or that the transaction code matches the transaction code a previously accepted payment code recorded in memory device 39.5, the payment code is rejected. If, on
-14AP Ο 00 3 1 6 the other hand, the result of the verification is that the extracted device identity code does match the device identity code of the control device in question, and the transaction code does not match the transaction code of a previously accepted payment code, the transaction code is recorded in the memory device 30.5. Depending on the extracted utility code, the appropriate one of the registers 30.1 to
30.3 referred to earlier is incremented by an amount c o r r e s po n d i n g to the amount code, thereby crediting the control device 10 for the provision of the relevant utility to the respective user.
It will be appreciated that there are many variations in detail on the system and control device according to the invention without departing from the scope and spirit of the appended claims.
