Abstract

A prepayment system for electric power or other utility commodity distribution uses radio frequency identification (RFID) tag technology to store and transfer value (money or KWh) from the retail vendor to the customer, and deliver power to the customer from the power distribution system. The customer purchases power at a retail outlet in the form of a credit to his Card containing an RFID tag. The Card is credited for the amount purchased by the store clerk, using the store'"'"'s Sales Terminal. The customer takes this Card to his residence or small business and holds it up to the RFID reader/writer sealed into the face of the System Controller. This System Controller is installed at a convenient location near, on or within his premises. Alternatively, he may use an optional Remote Terminal installed inside his premises. In either case, the display associated with the reader/writer indicates to the customer the amount of power remaining. The System Controller then stores the new deposit in the Meter/Contactor associated with the particular customer'"'"'s circuit. Mounted at the top of the pole, on the building or inside the building, the Meter/Contactor measures usage, decrements the customer'"'"'s credit, and shuts off power if the credit is depleted.

Claims

1. A utility payment system comprising:

a remote communication unit including a utility meter having a payment acceptor integral with or proximate said meter;

a customer interface unit for conducting a transaction;

radio frequency identification (RFID) communication means for communicating between the payment acceptor and the customer interface; and

a control system adapted to effect payment for a utility transaction through value received through said payment acceptor via said wireless communication electronics.

2. The system of claim 1 wherein said customer interface unit includes:

available value storage means for storing data representing a prepaid amount;

means for selectively incrementing said prepaid amount in response to customer payment; and

means for decrementing said prepaid amount by said value received in response to said payment for a utility transaction.

3. The system of claim 1 wherein said utility meter is an electric power consumption meter, said system further comprising means for enabling delivery of electrical current through said power meter in response to said transaction.

4. A method for conducting a utility transaction at or near a utility meter with a remote communication unit, said meter having a payment acceptor integral with or proximate said dispenser, comprising the steps of:

a. adding a value received through said payment acceptor to a prepaid value stored in association with said remote communication unit to increase the prepaid value stored in association with the remote communication unit;

b. using RFID, reading the prepaid value stored in association with the remote communication unit;

c. totaling a purchase cost for a utility consumption subject to the transaction;

d. deducting the purchase cost from the prepaid value to calculate an updated prepaid value; and

e. using RFID, storing the updated prepaid value in association with the remote communication unit.

5. The method of claim 4 wherein:

the storing step in (e) further comprises reading said prepaid value from a database apart from the remote communication unit and writing the updated prepaid value to said database apart from said remote communication unit;

a customer prepays for subsequent transactions at a terminal capable of communicating by RFID with said remote communication unit to store said prepaid value on said remote communication unit.
