I have a NFC app on my phone, read one of those buttons ... they left it unlocked, so I posted a message. Not sure anyone will read it, presumably they just pick up the location ID in an app. I guess someone could just clone the locations and sit in a chair and spoof it.
Library books in my area use NFC, the tags weren't locked on the last book I checked.
Probably not a security problem (ha!?), but you'd think the possibility of vandalism would cause them to be locked.
- ticviking 6y agoI've often wondered how often NFC is unlocked like that.
- HenryBemis 6y agoI've seen buildings where the buttons are 'burried' in a few mm 'deep' the wall, and painted over so that you don't notice them at all, the wall looks really smooth. The guards know where exactly the spots are, you see them waving their devices in a seemingly flat/blank wall, then the beep sounds, and they walk towards their next 'random' spot.
