#133116 - Credit Card Reader Using a PIC12C509 Responding to: ???'s previous message |
Hello Mircea Gliga,
There is an excellent article at this address http://ww1.microchip.com/downloads...00727a.pdf showing how to build a Credit Card Reader Using a PIC12C509. You can us a PIC12F629 (8 pin dip reprogrammable $1.50/1 ea.) in place of the PIC12C509. The article shows the hardware interface to a reader and output to a serial port of a computer. There are programmers, Software to program the PIC12F629 and IDE debuggers for free all over the Internet. This article also shows how to sync the credit card which is most likely the problem you are fighting now using the AT89C2051. Good Luck. Regards, Charles Bannister |
