This is pretty clever. The major improvements I&#x27;d want to make are some sort of RFID chip that deactivates the magnet when I&#x27;m close enough, instead of a fingerprint scanner. It seems like anyone who gets close enough can see the scanner, so I&#x27;d prefer to have something more invisible.<p>And the second thing would be just to improve the lag time between grasping the handle and the deactivation of the magnet, so I can just lean down and casually grab it, instead of having to hold it for a second before bringing it up. The more magic, the better.<p>Still, this is pretty awesome!
