Smart Locker is an automatic locking system that relies on ICT. The device is composed of three components for use with a variety of furniture to fit a user's work style. The lock offers the best storage format, both a touch key for casual security and a fingerprint key for high-level security. The lock also offers a quick lock/unlock function with non-contact use through a smartphone app, NFC, RFID, fingerprints, and passwords. The lock creates a safe work environment in the Covid-19 era, thanks to its non-contact functionality so that users need not touch a surface used by someone else.
