NFC (Near Field Communication) Tags are tiny stickers, cards, and keychains that can store and send information to a phone when tapped. They don’t need to be charged because they get power from the phone when they come close together.
NFC tags are used for many things:
- Quick Actions: Tap your phone on a Tag to turn on WiFi, open an app, or play music
- Contactless Payments: Used in credit cards and Apple Pay/Google Pay to make purchases
- Smart Business Cards: Tap a Tag to instantly share your contact information
- Access Control: Used in keycards for doors and event passes to enter restricted areas
- Home Automation: Used to turn on/off lights, adjust thermostat, control fans, etc.
How to add data to an NFC Tag:
- Step 1: Purchase an NFC sticker, card, or keychain online
- Step 2: Download an NFC app (e.g. NFC Tools)
- Step 3: Choose what you want the Tag to do (share contact details, turn on WiFi, send message, etc.)
- Step 4: Write the data to the Tag – Hold your phone close to the Tag, press “Write” and the phone will save the info onto the Tag
- Step 5: Test it – Tap your phone on the Tag to see if it works
