Ya, all those cardkey locks are computer controlled. It is easiest to use a RFID reader and just steal a cardkey data of someone passing by. However, I wonder if an app could get a droid to transmit an RFID code?

The new NFC systems should be able to do some of that if they aren't active systems.  (ie door sends a random #, the card then encrypts it with an id code attached and sends it back to authenticate).  Even if that's done, the next step of door sends to central station for decryption, followed by central station sends to door to unlock.  My guess is they are just echoing the central station tells door to unlock message and it's not encrypted.
