The Handle is an award winning concept design that uses invisible tech for a smart lock door handle. It has multiple sensors that detect movement as you are getting close, the back lighting would automatically turn on to guide you where to touch the backside of fingerprint identifying area.
Instead of just using numbers as password, The Handle also allows you to create secret pattern or uses different shapes combination to unlock the door. There’s no extra handle as well, making it slim, minimal, and elegant.
The Handle by Wayne Lu and Wenjie Zheng uses laser micro through touchscreen keyboard with invisible light to provide different types of password. The home owner can press the indoor unlock key to open the door, or toggle the switch to keep the door locked.
