- Works just like a prepaid card style public phone pay-as-you-go model. Insert card, get power; remove card, power ceases; credits is deducted as power is consumed.
- Ideal for short term rentals such as apartments and market stalls; serves as a simple form of management.
- Amount deducted proportional to amount consumed, reader displays the credits remaining, power is cut off once credits are used up.
- Use the function key on the card reader to switch the display to show the remaining credits, power consumed and tariff rate.
