For example, I have a tag at my bedside—tapping it automatically puts my phone in Do Not Disturb mode and dims the lights.

Card Emulation Mode

Here, your Android device acts like a contactless card—this is how Google Pay works. It uses secure elements or Host Card Emulation (HCE) to transmit encrypted payment data to point-of-sale terminals.

Every time I pay for coffee with a tap, this mode ensures my real card number stays protected.

Peer-to-Peer Mode

This lets two devices exchange small files or data—like sharing contacts, photos, or URLs—without needing to pair or connect to a network.

I once used this at a tech event to instantly swap contact details with another attendee by just tapping our phones together.
