Protect beer with RFID system

Beer is precious liquid and no one wants to give it away for anyone. It is best idea is to share it with friends and keep away from strangers. This is how guys from Milwaukee hacker space thought. They have plenty of beer but they want it to keep that way. So they developed some sort of security system with RFID.

As always this is based on Arduino board which interfaces RFID reader and Nokia 5110 LCD screen. They didn’t bother with nice setup – just hang RFID reader on refrigerator door so anyone with access key could unlock dispenser and have a sip of cold drink. When card is read and there is a code match LCD screen shows friendly personalized message. Dispenser not only serves as security system but it also keeps track of dispensed beer – now they will know who’s gonna refill that fridge.
