It is now possible for your clients to top up their Prepaid Ledgers by paying money online.
The way this operates is through Monsterpay (www.monsterpay.com). You configure your own merchant info into pnpscada, so the money relationship is directly between the reseller/landlord and monsterpay, it has nothing to do with pnpscada.
They charge 2% for payments via EFT. This means that as far as prepaid fees go, PNPSCADA via Monsterpay is one of the cheapest prepaid solutions for landlords.

Monsterpay is closing down!
Please use PayFast instead. Plug and Play SCADA supports ledger payments via PayFast as well.
