i do on computer security but i feel a lack between IT and hardware. my study nowadays is on malware and pen-testing, but i have a passion to learn about magnetic and RFID cards, how data being stored and read.
does arduino provide all needed pieces to create a magnetic card reader? if yes, would it be cheap or there is other alternative ways to build a card reader/
