Management program through a system of prepaid cards
MiFar
The Cash card Access System is designed for the application of Mifare cards at 13.56Mkz compliant with ISO 14443A. The idea is that consumer pay for all consumption by card instead of cash, First the said Mifare card needs to be programmed and stored with values or amounts by a Read/Write Device (RWD), PRW106. Then consumers bring the programmed cash card with them to the Reader end, AC906, for transaction. Whenever the cash card is read by AC906, the present decrement will be deducted from the card and the new value or amount will be rewritten to it.
This system can also be applied for Access Control purpose.
