If I forget my keys (most likely they will be on the desk but silly me left the desk without them), I may have my wallet with me.

So I used a credit card which is NFC enabled to readout the NFC information, added this number to the database and can now open doors using my credit card. I am tired of carrying around the tag, people keep loosing it, forgetting it and it would be nice to open the door using a Phone - which we tend to always have on us. We carry around a little NFC tag on our key chains which will read out a number and this then will open the door if the number matches a number in the database.


At my office the doors are locked with an NFC reader.
