In this post I describe how my cheap magstripe reader wouldn’t read all magstripes, only credit/debit cards. This did nothing to help me understand what data was on my hotel key card – which is what I really wanted to know. Rather than take the obvious next step or buying a better reader, I opted to open up the cheap magstripe reader, probed around a bit and found a way to read the raw data off the hotel magstripes.
