One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →3M Hook and Loop Fastener consists of flexible J-shaped nylon hooks and woven loops which engage each other to form a quick attachment. It offers an alternative to zippers, screws, snaps and hooks, bolts and more.
Hook and loop fastener creates smooth joints without screws, rivets, bolts or zippers
Rubber adhesive allows for attachment to low surface energy substrates
Woven nylon design provides durability for thousands of closures
