Hi,
I've came across a cool system for opening door by tapping it with a mobile phone. If you have NFC phone, you download NFCporter identification app to it (play.google.com/store/apps/details?id=cz.ima.nfc.p2pid), configure it to communicate with the door reader (you must buy theirs or some other with NFC capability may be also suitable, I think) and you should be able to enter just by tapping your phone.
I am currently waiting for my reader, so I will let you know when I test it.
