What is NFC?
NFC stands for Near Field Communication. It’s a short-range wireless technology that allows devices to exchange information when they are brought very close together (usually within a few centimeters). NFC tags contain small amounts of data (like a web link, contact info, or a command) that your phone can read.
Before You Scan: Essential Checks
- Device Compatibility: Ensure your smartphone has NFC capability. Most mid-range to high-end smartphones made in the last several years do. You can usually check your phone’s specifications online or in the settings.
- Enable NFC (Especially for Android):
- Android: NFC usually needs to be manually turned ON.
- Go to Settings.
- Look for Connections or Connected Devices (this varies slightly by manufacturer).
- Find NFC or NFC and contactless payments.
- Make sure the toggle switch is ON.
- Quick Tip: Many Android phones have an NFC toggle in the Quick Settings panel (swipe down from the top of the screen).
- iOS (iPhone): NFC for reading tags is generally always available on compatible iPhones (iPhone 7 and newer) when the screen is on. You don’t need to toggle a specific setting just for reading tags. iPhones XS/XR and newer support “Background Tag Reading,” meaning you don’t even need an app open. Older models (7 to X) might require an app to initiate scanning or for the tag to trigger a notification.
Finding Your Phone’s NFC Antenna
This is crucial! You need to touch the correct part of your phone to the tag. The location varies:
- iPhones: The NFC antenna is typically located on the top edge of the phone, near the back camera area.
- Android Phones: This varies widely!
- Often it’s on the back of the phone, towards the center.
- Sometimes it’s near the camera module.
- Some models might have it elsewhere.
- Tip: If unsure, do a quick web search for “[Your Phone Model] NFC antenna location” or try slowly moving the back of your phone over the tag until it registers.
How to Scan the NFC Tag
- Unlock Your Phone: NFC scanning generally only works when your phone is unlocked and the screen is on.
- Locate the OwnerLock NFC Tag: Identify the OwnerLock NFC tag you want to scan. It is indicated with the OwnerLock and NFC label.
- Hint, if you find it challenging to access with your device, you can scan it from the other side too – for example, if it is inside an attaché x briefcase, you can tap and hold your phone on the outer side in the same area.
- Bring Your Phone Close:
- iPhone: Bring the top edge (back) of your unlocked iPhone close to the NFC tag (within ~4 cm or 1.5 inches).
- Android: Bring the back of your unlocked Android phone (specifically the area where you believe the antenna is) close to the NFC tag.
- Hold Steady: Keep the phone steady near the tag for a second or two. Don’t wave it around quickly.
- Look for Confirmation:
- iPhone: A notification should pop up automatically at the top of the screen. Tap this notification to open the link associated with the tag.
- Android: You might hear a sound, feel a vibration, and/or see a notification or pop-up on screen. Tap any notification if required.
Troubleshooting Tips
- NFC Not On (Android): Double-check that NFC is enabled in your settings.
- Wrong Spot: You might not be aligning the phone’s NFC antenna with the tag correctly. Try moving the phone slowly over the tag, focusing on the likely antenna location (top for iPhone, back-center/camera for Android).
- Phone Case: Thick or metallic phone cases can interfere with the NFC signal. Try removing the case.
- Too Far/Too Fast: Ensure you’re holding the phone very close and steady for a moment.
- Tag Issue: The NFC tag itself might be damaged or faulty.
That’s it! Once you know where your phone’s antenna is and ensure NFC is ready, scanning tags is usually a quick and simple process.
