Well I saw that we sell these things are work now and they don't require your social to buy one for $10 so I thought this could easily be turned into a skimmer,(for a proof of concept thing I would do for youtube) however this is not as easy as I expected. Maybe you guys can help me out here.
It seems very simple, the device just converts the magnetic strip data to sound that you could use a variety of programs to decode.
My first problem, I can't even get sound. I plugged it into the microphone jack on my computer. and of course nothing, I figured that was a bit too complicated with drivers and what not; so I grab my digital voice recorder and plug it into the external Mic jack. swipe a card. still no sound.
