- tux1968 5y agoOkay, but that would work for a BT device too. I was mostly curious why BT was seen as a bad choice and more vulnerable than another option.
- xaduha 5y agoThis whole comment tree kinda got derailed into bikeshedding about BT with confusion between replay and repeater attacks to boot. It probably isn't any more susceptible than similar RF alternatives. Personally I wouldn't want a BT key because I used smart rings, namely a contactless payment ring and an OMNI ring. They aren't without issues, but they are miles ahead of a device like Chameleon Tiny Pro (which I also used) when it comes to usability. There might be smaller BLE devices out there, but it is pretty small. About the same as Google Titan BLE based on the images.
