title: Get Raw Magstripe Data with audio jack reader
body: <p>So i have recently acquired a few paypal magstripe card readers for free. My goal is to use this to get the raw data via the audio jack on an android device. My best guess at how to do this would be to use the AudioRecord stuff in android, then decode the audio signal. Would this be the best way? Anyone else tackle stuff like this? Examples?</p>
