A Smart lock for your front door: Stam Smart Lock Solutions; SSLS, has developed a prototype of a smart lock for your front door, so the old fashioned key is no longer necessary.
You put the smart key, a Credit card sized RFID card, in your wallet or bag and as you walk up to your door the door opens automatically. You can walk right into your home with a gentle push on the opened door, keeping the bags you are carrying in your hands.
