@thor I have noticed this too. In IT my boss had an Apple Watch and I was surprised what he used it for. He used that watch for the NFC capability to unlock controlled areas. We were still using the latest Mifare cards but it was decided we needed more encryption. Essentially they swapped to smartphone and smartwatch authentication which is a rather robust solution.

I opened the same doors with a screwdriver. Sometimes it pays to be a Locksmith.
