Hackster.io users Team CodersCafe: Shebin Jose Jacob, Nekhil built a biometric lock that allows users to use a mobile app to unlock a door:
All the components used in this project are very cheap
1. Fast Unlocking
The fingerprint sensors equipped on mobile phones are really fast and since firebase is a real-time database with a very high speed of operation the locking-unlocking process will be very fast, less than 0.5 s.
2. Advanced Security
The Android application provides cryptographic algorithms that ensure the security of transmitting data, thus the lock gets multi-layer security.
3. Shareable
By sharing the Android application and the Firebase credentials multiple persons can access the same door.
4. Portability
This door lock can replace any lock. Just replace the locking mechanism with this and it will become a smart door.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
