RFID or Smart Card Cashless Payment System? http://www.instructables.com/answers/RFID-or-Smart-Card-Cashless-Payment-System/ http://www.instructables.com/static/defaultIMG/default.SQUARE2.png http://www.instructables.com/static/defaultIMG/default.SQUARE.png http://www.instructables.com/static/defaultIMG/default.SMALL.gif 7_7 Hello! I was wondering if it was possible to make a cashless (apart from adding funds) payments system. I was thinking it could be done with an Arduino and RFID reader/writer OR smart card reader/writer. The balance would be stored on the card (AFAIK data can be stored on the cards) and when the pe...

It gives out an analog signal, which i have connected to my Arduino's A0 pin, and uploaded the analogRead sketch to it(sends values to serial port too). Then to visualize the heartbeat i used a processing ...
