HC-05 Bluetooth Chip also used in Credit Card Skimmers. (Also, a way to test Bluetooth?)

I was looking at the Sparkfun site this morning and noticed that Nick over there had come up with a small app for Android that sniffs for Credit Card Skimmers that commonly use a certain HC-05 Bluetooth Chip, and also uses a default PIN of 1234. It's a fairly interesting read. https://learn.sparkfun.com/tutorials/gas-pump-skimmers?_ga=2.115120007.1258160143.1506310662-672536110.1502411582

That being said, I have downloaded the app and will see if it tags the AltairDuino when I get home tonight. I'm guessing it will. (I had planned on changing the PIN once I have everything built and tested anyway...)

On reading more, it seems that part of the testing protocol is a Challenge/Response test. I guess this makes the post somewhat "OT". (But still interesting)

Interesting story! Kind of scary how cheap and easy it is.
