Share WiFi Password with NFC
Learn how to create NFC tags that instantly share your WiFi network. Perfect for guests, offices, cafes, and Airbnb hosts.
What You'll Need
- iPhone 7 or later with iOS 14 or newer
- NFC Taggy Tools app installed from the App Store
- Blank NFC tag (NTAG215, or NTAG216 recommended)
- Your WiFi network name (SSID) and password
Step-by-Step Guide
Download and Open NFC Taggy Tools
If you haven't already, download NFC Taggy Tools from the App Store. Open the app on your iPhone.
NFC is always enabled on iPhone and doesn't require any settings changes.
Select WiFi Configuration
From the home screen, tap on "Write Tag" button and select "WiFi" from the data type options.
Enter Your WiFi Network Details
Fill in the following information: Network Name (SSID) - Your WiFi network name exactly as it appears. Password - Your WiFi password (case-sensitive). Security Type - Select WPA2/WPA3 (most common), WPA, WEP, or Open (no password).
For hidden networks, make sure to check the "Hidden Network" option if available.
Write to NFC Tag
Tap the "Write to NFC Tag" button. Hold your phone near the blank NFC tag. Keep your phone steady until you see a success message (usually 1-2 seconds).
The NFC antenna is usually located at the top or center back of your phone. Try different positions if it doesn't detect immediately.
Test Your WiFi Tag
Use another device to tap the NFC tag. The system will display a notification asking to join the network. Tap "Join" or "Connect" to connect. Verify that the device successfully connects to your WiFi network.
On iPhone, a notification banner appears at the top of the screen
On Android, a dialog or notification prompts you to connect
Place Your Tag (Optional)
Stick your NFC tag in a convenient location like your front door, office entrance, or guest room. Consider adding a small label like "Tap for WiFi" so guests know what it does.
Avoid placing tags on metal surfaces as this can interfere with NFC signals. Plastic, wood, or glass surfaces work best.
Troubleshooting
Tag doesn't connect to WiFi
Double-check that you entered the correct SSID (network name), password, and security type. Make sure there are no extra spaces. For hidden networks, ensure the "Hidden Network" option is enabled.
Phone doesn't detect the tag
Make sure NFC is enabled on your device. Remove any thick phone cases. Try holding your phone in different positions over the tag. The NFC antenna location varies by device model.
Write failed or tag is read-only
The tag may be locked or damaged. Try a new blank NFC tag. Make sure you're using a compatible tag type (NTAG215/216 recommended).
Tips & Best Practices
Use NTAG216 tags for maximum compatibility and storage capacity
Place tags at eye level with a small "Tap for WiFi" label
Create multiple tags for different locations (entrance, guest room, office)
Test the tag with multiple iPhones before deploying to ensure it works correctly
Consider password-protecting the tag to prevent unauthorized changes
For businesses, use professional-looking NFC cards or stickers with your branding
