TL;DR – In order to get raw parsed data out of a magstripe reader, we first experimented with a MAGTEK Centurion Keyboard Encoder (PN-21073062). We found that although we could get all 3 tracks of data, it was not possible to have it parsed out. We then purchased a raw magstripe decoder head with track 1 reading, the Omron V3A-6. By writing some parity checking code, we were able to read the raw data off of the magstripe, and parse it into output that would be ‘typed out’ as an emulated keyboard using a USB-enabled Teensy. An Arduino can also be used, and the data would be output as Serial which may also be useful.
We also suggest checking out StripeSnoop which despite being a couple years old, was extremely useful!
This project can only be used for card reading, not writing. There is no way to convert a card reader into a card writer.
So there I was, 5 days before HOPE (Hackers on Planet Earth) conference – getting ready for our booth that would be running all weekend. We had a similar booth at the previous HOPE, and it was pretty successful, one of the only things that hung us up was that we couldn’t easily accept credit cards and the ATM had run out of money. We could take credit cards but it took a long time and was typo-ridden because everything had to be entered into a website. See, instead of a boxy terminal, we were using a Virtual Terminal – a website that allows you to enter in all the important data (card number, expiration, name, amount, etc).
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
