I don't indulge in drinking nor do I promote drinking habit among others but here is an RFID implementation which will find favor with people who like beer especially youth. I remember during college days one of our mates used to be fond of beer and was rich enough to stock beer in the apartment but other guys sharing the apartment could not afford a beer a day therefore they used to end up stealing from his stock which led to terrible fight at times but had he been a student in the current era he would have never experienced instances of his favorite bottle being pilfered since technology would have guarded his prized possession from stealing eyes.

Here is DIY RFID Beer Safe in which you can keep your bottles and spend your time concentrating on other aspects of life rather than worrying about whether your bottles would get stolen in your absence. The only thing you will need to worry about is keeping your RFID Card safe with you as it would act as access key for your fridge.
