About this app

[Description]
"SmartPassLock NFC" is a security lock screen application using the NFC (Near field communication).
You can protect the device which you are using from a malicious third party.

[Basic usage]
1. After installation, initial setup starts, and you register IC cards ("Suica", "nanaco", "Edy" and so on).
2. After you check that NFC is ON, the device is locked when device is in sleep mode.
3. The lock screen appears when you push the power button, and you can unlock it by touching it with the registered IC card.

You can register some IC cards ("Suica", "nanaco" and so on). You can prepare spare IC cards just in case that you lose the registered IC card, You can share the devices only among the people who are permitted to use them.
You can add the registration upper limit by buying Add-on.

[Monitoring mode]
In addition to the normal mode, there is the Monitoring mode. While the monitoring mode is working, When Monitoring mode is enabled, "fake" pattern lock is displayed on lock screen.

The photos are saved in Gallery application.
On the Monitoring mode, you can unlock the device by touching it with a registered IC card like a normal mode.

Ratings and reviews

If the intent is to lock someone out who isn't tech savy, this is perfectly good. However, after my cat stole my yubikey and I had no way into my phone, I figured out all I had to do was reboot the phone and race the app. I managed to stop the service before it locked me out and then remove it. Additionally, there is no backup authentication method if you lose your key. This set me in panic mode when I lost the key, which lead to discovering how to bypass it.

Does not work on my Pixel 3 stock. (1) After authentication and it returns control over to the stock Google Pixel 3 home application, "Pixel Launcher", the launcher no longer works properly. The is NO WAY to swipe up and get to your app drawer. So there is no way to access your apps AT ALL unless you have dragged one to the desktop or you completely uninstall this app. (2) Tapping the home button on screen does not return to your home page of apps (3) My in-purchases are lost if I reinstall it

While the app works like it should and allows unlocking with a NFC key I have found that against a very determined adversary it is entirely possible to override this app and gain access to a phone without the physical key. If someone can unlock your phone they can hail Google Assistant and "Open Settings" this app will fight but fast switching between the lock and settings screen allows you to eventually force stop the app and the phone is now unlocked.
