This is a USB keyboard emulation device, so when you swipe a card, the data on tracks 1 and 2 are typed on the screen into whatever program you have open at the time. No worries I figured, this will make hacking at it that much more fun. Last edited by lazlow; at The configuration name and the module name are listed: I’ve been on Google for a while now but I’m not sure if any of the card readers I find will work with Linux. I didn’t find any instructions that were as straightforward as they should be, so Linux – Hardware This forum is for Hardware issues.

With this information confirmed I figured I would approach it with the same method used in one my older post Python Device Hacking Keyboard. I’m trying to learn about USB reverse engineering, so I’m trying to understand how this device sends data to my computer. The former involves install a device with a Windows driver HID driveror as a keyboard alternative.
