It's the thirst for improvement which prompts a man to think beyond his boundaries and that is what my friend Dave has done. He used to notice people installing RFID passive readers outside their front door and utilized RFID tags for unlocking them from outside but he wanted a better control over his door lock. In order to improve things he worked on a project where one will be able to lock or unlock their doors remotely using either their computers or cell phones. This would enable you to command a better control over the security of your house and the RFID key fob being used could also be charged on the other side of door transmitted back to the reader through the door.

Besides making your life a bit easier it would also not give robbers a chance to get attracted to your house and make it their next target. Check out this video to know how it works!!
