I easily cloned access cards to the building of a club I'm a member of, as the company managing the security access went the way of the dodo. Granted, it's not a long term solution, but it's a stop-gap measure that allows us to use the facilities until the landlord replaces the system/company. Would I have been able to do that with my professional equipment at my office? Of course, but doing it in the field with a cute dolphin winking at me is nice. I was able to show that one of my client's building access control is less secure than their lunch system, and for the NFC work I'm doing with some clients, it allows me to have a single device in my pocket with the 30 or so keys in use on the project instead of having 30 dongles in my backpack.
