BUYING ELECTRICITY VIA TOKEN

An STS prepayment meter can be  installed in a consumer's house, and the vending points where consumers  purchase  electricity  are established at convenient locations, near  consumers' houses. The vending management system is located at the utility offices. This mechanism will provide all the information and data regarding the various vending points, including reports and audit trails.

The consumer goes to their vending points (POS) (this could be a local store, the utility financial offices, a supermarket or petrol station), and purchases a token in exchange for equivalent cash. The token comprises a 20 digit number encrypted.

The consumer  inputs this 20 digit number through keypad of meter,and the meter receives, de-encrypts and adds it to credit register.

When the credit has expired, and no new token is entered, electricity supply will be automatically suspended.

The supply of electricity will resume after new valid token is inputted.
