Mobile commerce company SWAP Mobile has launched a mobile prepaid electricity voucher service which lets users buy electricity vouchers in minutes, directly from their cellphones and wherever they are.

The electricity voucher service is a new function in the SWAP Wallet, a payment tool already available on all South African cellphones.
The SWAP Wallet, launched in 2008, is used by cellphone owners to pay bills and COD charges, as well as to purchase airtime for any network directly from their phones.
To make use of the service, an electricity customer needs to register a free SWAP Wallet.  Any cellphone user – regardless of handset type or the cellphone network – can activate a Wallet by dialling *130*1313# toll-free and following a series of onscreen prompts. Once registered, the user can load vouchers into his or her SWAP Wallet and start transacting.
An existing credit card may be linked as a payment option, or a bank account as a source for Wallet voucher top-ups initiated from the phone.
Once registered, electricity purchases are just as simple. The user dials *130*1313# and follows menu prompts to purchase electricity to the value of his or her choice with payment made from the Wallet, or from a linked credit card if the linking option has been taken.
