How to use your pre-programmed NFC Keychains

You’ll need a compatible smartphone or tablet (iPhone 7 or newer, or most Androids)

NFC must be turned on (don’t worry, we’ll show you how)

📲 Step-by-Step Instructions:

1. Unlock Your Phone

Make sure your phone is on and unlocked — NFC won’t work if your screen

is off or locked.

2. Turn On NFC (if not already on)

🔹 For iPhone: Just unlock it — NFC is always on!

🔹 For Android: Go to Settings → Connections → NFC → Toggle it ON

3. Tap the Keychain to the Back of Your Phone

Hold the NFC keychain flat against the upper back of your iPhone (usually at the top)

Or

near the center-back of most Android phones

Wait for a notification or action to pop up

4. Follow the Link or Action

A pop-up will appear — usually a link, contact card, or other programmed info.

Tap it to open!

5. You're Done! 🎉

That’s it. No apps needed, just tap and go.

⚠️ Troubleshooting

📴 Nothing’s happening?

Try adjusting the position or flipping the keychain around.

📱 Still not working?

Make sure NFC is on. Some phones need extra permission settings enabled and

older models may not have NFC reading capabilities.
