The hardest part is to name things, so why not ask the beloved community about it?
RfidResearchGroup has with proxgrind's magic hands made a new bluetooth, battery addon for the Proxmark3 RDV4. It uses the FPC connector to enable the Proxmark3 to get a serial over bluetooth to set it free from usb cables. Think in terms of letting your android phone communicate with your device. Your Proxmark3 RDV4 will become a very sneaky device.
No more large usb batterys and y-cables. No more raspberry pi + proxmark3 + battery, No more bringing a laptop to the front gate when you are trying to do a simulation reader attack.
So what shall we call this device? Just add you suggestions because we don't have any good ones yet.
Feel the love!
