The thing with RFID / NFC locks (padlocks or otherwise) is, if nobody else has tried them before, it’s a bit of a gamble whether they work with implants or not. Less so with flex implants of course, but performances can be iffy even with narrow flexies.
The only model I ordered sight unseen was the U&Z CX2172 because I knew with 100% certainty it would work with my (then not-yet-dead) flexNExT. Fortunately, it also works with the flexDF / flexNT, because the flexNExT sure isn’t an option anymore. But that was lucky.
The fact that Digiwell lists that stupidly expensive Wilka padlock as working with implants is the only reason why I let my wallet be raped: I paid extra to be sure it would work essentially - and at that price, it’d better work
