A few times I have locked myself out of the house and needed to wait for the Wife to get home and unlock the door. So I decided to come up with a way to get inside the house if I am outside and have nothing on me. Using RFID tags hidden around outside I can put them to the reader on the door and have the door unlock. If I have my phone on me I can also unlock the door via an app I created.
