NFC Tags for Contact Sharing

Program Your NFC Tag to link to ScanKeep

Then anyone who taps the tag once goes to your ScanKeep profile, product page, or support link.

NFC example
What you’ll need
  • iPhone 7 or newer (iOS 13+ recommended; newer iOS works best)
  • Your rewritable NFC tag (on back of business card in your package)
  • Your ScanKeep user link (e.g., https://scankeep.com/u/yourURL)
  • An NFC writing app for iPhone (e.g., NFC Tools or any trusted “NFC Writer” app)

How to Write Your ScanKeep URL to an NFC Tag (iPhone)

  1. Install & open an NFC writer app
    Popular options include NFC Tools (iOS). Open the app and choose an option like Write or Add a record.
  2. Select “URL / Web”
    In the app, add a new record of type URL (sometimes shown as Web address).
  3. Paste your ScanKeep link
    Paste or type your exact ScanKeep user URL (include https://). Example:
    https://scankeep.com/u/your-username
  4. Prepare the tag
    If the tag was used before, tap the app’s Erase/Format feature first (if available) to clear old data.
  5. Write to the tag
    Tap Write in the app, then hold the top/back of your iPhone close to the tag until the app confirms success.
  6. Test the tag
    Exit the app and tap the tag with your iPhone. Safari should open your ScanKeep page immediately.
  7. (Optional) Lock the tag
    If you want the URL to be permanent, use the app’s Lock/Make read-only option. Note: locking usually can’t be undone.
Tip: Apple’s Shortcuts app is great for triggering automations when you scan a tag, but it doesn’t write web links into tags. Use a dedicated NFC writer app for encoding your ScanKeep URL; use Shortcuts later if you also want automations.

Troubleshooting

The tag doesn’t open my link
Confirm the tag is NDEF-formatted and not locked. Re-write the tag and ensure your URL includes https://. Try another writer app if needed.
My iPhone won’t detect the tag
Move the tag to different positions near the top/back edge of the phone and hold steady for a moment.
The tag won't read at all
For older iPhones or to create specific actions with NFC tags, open the Shortcuts app.

Best Practices

  • Label your tags (e.g., “ScanKeep Profile”) so it’s obvious what they do.
  • Use waterproof or on-metal tags for fridges, cars, or outdoor spots.
  • Keep a note with your ScanKeep URL handy for quick re-writes.
  • Test with multiple phones when possible; Android and iOS can behave differently.

FAQ

Which iPhones can write to NFC tags?
iPhone 7 and newer can write standard NDEF records (like URLs) when using a compatible NFC writer app. For automations, Shortcuts supports NFC triggers on newer models.
Can I use Apple Shortcuts instead of a writer app?
Shortcuts is great for triggering automations when you scan a tag, but it does not encode a web link into the tag. Use a dedicated NFC writer app to write your ScanKeep URL.
