How to use an NFC tag in Android to unlock a phone without an extra keypad

I’ve been using a variety of Android devices lately and I’ve always wondered how to unlock them using NFC.

I can’t tell you how many times I’ve tried to use the NFC tag on the phone, only to get it to “not work” because the phone has a non-standard pin configuration. 

I recently stumbled across a very simple method for unlocking a phone using NFC using an Android 4.3 (KitKat) and Android 4 (Ice Cream Sandwich) device. 

Here’s how to use it.

To unlock the phone using a simple NFC tag:1.

Connect the NFC chip to the device.2.

On the phone’s Home screen, tap the NFC button on the side of the phone.3.

On your device’s Home Screen, tap “Home” again.4.

Tap the NFC icon on the left side of your device.5.

Tap “Activate” and the phone will be locked.6.

You can also access your phone’s settings by pressing and holding the “Lock” button and tapping the “Set up” option.7.

When you’re finished, swipe down on the NFC “Toggle” button on your device to unlock the device by touching the NFC sensor.

You may also see the “Device is unlocked” notification pop up. 

It works great.

It’s a bit tricky to unlock an NFC-enabled device, but it’s worth the effort to try.
