Purchasing a token
The vending of prepayment electricity tokens is a one-way system in which tokens cannot be refunded upon
returned. This is because once a token has been issued, the only way that the supply authority could verify if
the token has been entered into the meter is to physically check the meter registry on the meter.
The user purchases credit tokens from a vending authority using the supplied user I.D card and the amount
the user wishes to purchase.
The 20-digit token is generated combining various elements such as the meter serial number, supply group
code and the date on which the token was vended.
When the user I.D card is not available or supplied, it is still possible to purchase electricity supplying the
vending authority with one of the following:
Meter serial number
Stand or property number
Name of property owner
Physical address
