I denne artikel, we’ll guide you through understanding how to scan NFC tags and teach you how to use this technology to unlock smart features in your life.
Trin 1: Check if your phone supports NFC
Most mid-to-high-end Smartphones on the market now have built-in NFC (Nærfeltskommunikation) funktionalitet.
- Android users: Go to “Indstillinger” > “Connectivity” eller “More Connections” and check if there’s an NFC switch. Make sure it’s turned on.
- iPhone users: All iPhone 7 and later models have built-in NFC functionality. iPhone 11 and later models don’t even need to be manually turned on; the system will automatically recognize and scan tags.
Trin 2: Determine the scanning location for your phone
This is the main reason why many users “can’t scan” tags. NFC tags are typically placed on the back of the phone, but the antenna location varies depending on the phone model:
- iPhone: The antenna is usually located near the camera area at the top edge of the phone.
- Android: The antenna location varies by model, but it’s usually located in the center of the back of the phone or near the camera.
Trin 3: Start Scanning
Unlock your phone screen (make sure the screen is on).
Bring the back of your phone close to the NFC tag (1-2 cm væk).
When the phone senses the tag, you’ll feel a slight vibration or hear a notification sound. A notification or webpage will then automatically pop up at the top of the screen; tap it to proceed.
Why is your scan not working? (Troubleshooting)
If you still have no response after multiple attempts, please check the following:
- Thick phone case: Metal or very thick shockproof phone cases may block NFC signals. Try removing the phone case and trying again.
- Read permission not enabled: Some Android phones require the “Read NFC Tag” function to be specifically enabled.
- Incorrect posture: Hold the phone in contact with the tag for 1-2 sekunder; do not move it too quickly.
- Damaged or Unwritten Tags: Some tags are blank or industrial-grade encrypted, which may not be directly readable by ordinary mobile phones.
