Background Research
My project is about creating a ring with an NFC tag to easily unlock an Android phone.
Becky Stern shows you how to unlock your phone just by picking it up-- make an NFC ring .
Overview:
Unlock your phone by just picking it up! No more pesky password or gesture PIN, just scan an NFC tag! This guide covers creating an NFC ring, putting an NFC tag in your nail polish, modding your Android installation to read tags from the lock screen, and creating an automation tool chain to unlock the phone when the desired tag is scanned.The software side of this project can be pretty tricky, and even scary if you've never jailbroken a phone before, which is required to get the phone to read NFC from the lock screen.However, you can still do a lot of fun projects without modding your Android install, just skip that step and head straight to the page about NFC+ Tasker Automation. You won't be able to log into your phone with your nail polish, but you could do all kinds of other things like start playing Barry White when you place your phone on the nightstand.
Concept:
Near Field Communication (NFC) is a short-range wireless connectivity standard (Ecma-340, ISO/IEC 18092) that uses magnetic field induction to enable communication between devices when they're touched together, or brought within a few centimeters of each other. It's a smart ring that can unlock a phone quickly by picking it up. It helps you save time and make things easier. My purpose is creating an NFC ring, putting an NFC tag in your nail polish, modding your Android installation to read tags from the lock screen, and creating an automation tool chain to unlock the phone when the desired tag is scanned.
Key Words:
NFC: Set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within about 4 cm (2 in) of each other.
