Happy with the NFC ring, but really wanted a way to "require" it regularly. I don't have an Android phone, but needed an Android device for my StickNFind Bluetooth trackers. So the perfect combo is Android device with NFC. A new SIM free phone was going to be stupidly expensive. The answer was the Nexus 7 2013. Bought at my local high street cataloque shop for a reasonable £169.99. Experimented with a few apps for unlocking (to have fun with the ring and to keep the ankle biters off my new tablet), and the one that did the trick was TapUnlock by MoonPi. It allows you to register two devices, so did both sides of the ring. (Mine is a bit too big so it spins). Requires a bit of practice to get the right action to unlock. Voila!
