Wearable Show: Using Apple Watch as a Key

Many people have "ignored" the Apple Watch, so don't waste this good piece of information. The Apple Watch can actually do some cool things, it just takes some time to come up with good ideas.

When the Arduino board with RF function detects an identifiable key, it will provide voltage to the electronic door lock card.
