Hi,
Can i interface online credit card reader with pic microcontroller like in this link **broken link removed**
Actullay in the given link there is no option for interfacing with microcontroller.this is just for reference that i want to use these kind of devices with microcontroller.
If interfacing can be done between both devices then what interface options we have like (rs232,rs485,IrDA,bluetooth etc).
What i want to do is that, first the user swap the card and the detail comes from online is read by the microcontroller.if the user have enough amount then microcontroller start the certain process.after the process ends the user again sweep the card and enter the amount to be deducted , this reading may or may not be read by the microcontroller.
It that scheme possible.
