Kindoo Access Control System

[PKSharp]

To add a little to my previous post, from Kindoo's own tech docs, if a devious person wanted to a cheap or broken screen phone of the same version could be wiped and restored from a backup of a valid user's phone, and that could be repeated for other simultaneous copies, and you'd suddenly have illegitimate phones/access out there. Yes there might be an initial phone access password needed to start the process, but it's possible. Admittedly that isn't likely, but where fobs go, while there are other issues, how often do they really get "copied" nefariously? I don't know, but would guess it's not very often, even though that argument continues to surface. And the little passive tags are dirt cheap, so replacing them can't be a cost issue when they do actually wear out or are lost (at which point the old one should be disabled anyway) compared to Kindoo. Pattern detection could possibly notice duplicates of either approach, but nefarious persons probably wouldn't bother anyway; as has been said, they'd just break the glass and do what they wanted.

Kindoo knows and tracks the device ID and has software in place to deal with someone trying to access using the same account on different devices. Restoring from a phone backup doesn't copy that device ID, so Kindoo would catch that. Cloning a fob using a Flipper would be much easier and undetectable. As you inferred, a properly-sized rock or brick is a much simpler, lower cost, more convenient and lower-tech entry tool .
