[Skunkworks] Hotel Keycard and Power System

Hi Guys, Looking for a system that does that key card thing for hotels where you get a key to open your door and slot it into some RFID thing to switch on the power. For 30 rooms. I'm guessing the door locks have to be reinstalled and rooms re-wired. Any suppliers please contact me off-list with costs. This should include training, installation and so on. Include all hardware (including PCs required).
