I had a dream last night and I’m sure a lot of you have thought about this, but what if there was an app that ran and worked with a proxmark3? Basically plugged your proxmark into your phone? Not sure if your phone would half to rooted to get something like that to run… I’m sure it would and plus maybe a driver. But how easy and convenient that would be?
Also store different card codes with notes so you could read and program on the fly. I feel like I want to dive down this rabbit hole.
