The NFC Tag: What They Are and How to Use Them

Unlocking the Power of the NFC Tag: What They Are and How to Use Them

In a world that’s growing increasingly wireless and connected, the NFC (Near Field Communication) tags are small but mighty tools that can streamline your daily life, enhance your business, and open new doors in tech-savvy creativity. But what exactly are NFC tags—and how can you use them?

What Is an NFC Tag?

NFC tags are small, wireless chips that communicate with devices like smartphones or tablets via short-range radio waves—usually within a few centimetres. Think of them like a digital post-it note that can trigger a specific action when scanned.

These tags don’t need a battery. Instead, they are powered by the device that reads them, making them both energy-efficient and highly versatile.

Common Uses of NFC Tags

You’ve likely already used NFC without realising it. Common examples include:

• Contactless payments (Apple Pay, Google Pay)
• Transit cards and key cards
• Tap-to-pair Bluetooth devices
• Digital business cards

But it doesn’t stop there. With inexpensive NFC stickers or cards, you can automate daily tasks or even add interactivity to products and experiences.

How to Use NFC Tags in Everyday Life

Here are some creative and practical ways to use NFC tags:

1. Automate Daily Routines

Place an NFC tag on your bedside table to trigger your morning routine:

• Set your alarm
• Turn on Do Not Disturb
• Launch Spotify or your favorite podcast app

2. Share Wi-Fi Details

Stick an NFC tag near your front door or in a guest room. Visitors can scan the tag to instantly connect to your Wi-Fi without typing a password.

3. Digital Business Cards

Place an NFC tag on the back of your phone or inside your wallet. With one tap, someone can get your contact info, LinkedIn profile, or personal website.

4. Smart Home Integration

Trigger smart lights, thermostats, or voice assistants. Example: Tap a tag at your front door to activate your “leaving home” scene (turn off lights, lower thermostat, etc.).

5. Inventory and Product Tracking

For small businesses and creators, like 3D printing or craft sellers, NFC tags can be embedded in products or packaging to:

• Link to setup guides
• Provide authenticity verification
• Offer special discounts or limited-time offers

What You Need to Get Started

To use NFC tags, you’ll need:

• NFC-compatible smartphone (Most modern Android and iPhones support this)
• Blank NFC tags (You can buy packs on Amazon or electronics retailers)
• An app to program them (e.g., NFC Tools, Trigger, or built-in options)

How to Program an NFC Tag

1. Download an NFC app like NFC Tools (iOS/Android).
2. Open the app and choose “Write.”
3. Select the action you want (e.g., open URL, connect to Wi-Fi, share a contact).
4. Tap your phone to the NFC tag.
5. Done! Your tag is now ready to use.

Tips and Precautions

• Not all phones support writing NFC tags, though most can read them.
• NTAG215 or NTAG213 tags are the most common and widely compatible.
• Tags are usually rewritable, but you can make them permanent after writing if needed.
• Metal surfaces can interfere with NFC, so use anti-metal tags or insulation stickers if needed.

Final Thoughts

NFC tags may be tiny, but their impact can be huge—whether you’re simplifying your morning routine or creating interactive customer experiences. With just a few dollars and a smartphone, you can start tapping into the convenience and customisation that NFC offers.
