 		 #90601 - RE: 'I Implemented something simillar.
Responding to: ???'s previous message
Dear Michael,
Thanks for your reply,

Your method is very good. The only problem I see is.
- If a customer buys 10 units.
- Makes full payment for 1 unit.
- Take out SEEPROM of paid unit and copy its content onto other 9.

My customers are smarter they will certainly do this and cheat if I use SEEPROM for storing the installment related data. How about storing all this information inside microcontrollers flash memory using IAP calls. I am using P89V51RD2 and P89C668.

Thanks & Regards,
Prahlad Purohit
