I use it at work to clone a customer's proximity card when I work in their building so they don't have to leave me theirs to get around. The one legitimate use I found.
I guess being able to trigger the customer service announcement without having to find a button in a store is nice.
That's ... not a legitimate use.
That's probably debatable, if they have permission. They probably shouldn't have been given permission, but that's a separate issue
I usually do it when we take over a customer's access control system and we we have half their doors on the new system and half in the old still and are migrating them over. I'm an electronic security tech, this is what I do for a living.
Ideally, there should be a visitor card available to be used, with its clearances configured as appropriate for the visitor in question. Having a person hand over their own card (and PIN, if applicable) isn't a great idea either, but it's far better than copying that card, with or without permission (probably without, if we're being honest).
Oh, absolutely. It's not something which should be encouraged, and against a well designed modern system it probably isn't possible (there must be some challenge-response type NFC systems on the market).
I'm just saying it isn't unambiguously "illegitimate"
There are. Hotels use them for door key cards so they can't be cloned.
Unfortunately.. I was trying to clone a room key to my phone so I could just tap to enter when I stay 10 weeks in the same room.
seems legit to me…
If you're using Crowley to support what's legitimate, you're gonna have problems.
that’s the only thing i use from him…
Oh I think I used it to unlock some extra characters in Skylanders at some point too, but I don't really play those types of games anymore.
