Second Me Sticker
Tap it anytime, anywhere.
How to Bind and Write Information to Your Sticker
When using the sticker for the first time, you need to bind it to your Second Me profile through our app.
Steps:
Open the App: Launch the Second Me app on your phone and log in to your account.
Start the Binding Process: On the app's main screen, tap "Share" -> "Sticker" to enter the binding wizard.
Align and Tap: Slowly bring the NFC sensor area on the back of your phone close to the sticker.
For iPhone: The NFC sensor area is located at the top of the phone, near the rear camera.
For Android: The NFC sensor area on most models is also at the top back, near the camera module. Some models may have it in the center of the back.
Hold Steady and Wait: Once your phone is close to the sticker, hold it still for a few seconds until the app shows "Binding Successful" or "Write Successful." Do not move your phone away immediately after tapping.
What to Do If Binding/Writing Fails?
If you repeatedly encounter failure messages during the binding or writing process, please try the following troubleshooting steps:
Adjust Position and Speed: Ensure you're using the correct NFC sensor area. Try approaching the sticker more slowly and hold it steady for 2-3 seconds after contact.
Remove the Phone Case: Thick cases or those with metal or magnetic components can severely interfere with the NFC signal. Please remove your case and try again.
Check the Sticker's Surface: Do not stick the sticker on metal surfaces (like metal phone cases, refrigerators, or the back of a laptop), as metal will block the NFC signal.
Restart the App or Your Phone: Occasional software glitches can cause writing to fail. Try force-quitting and restarting the app, or rebooting your phone.
Replace the Sticker: If none of the above solutions work, the sticker's internal chip or antenna may have been damaged during shipping or use. Please replace it with a new one.
What to Do If Tapping the Sticker Doesn't Work?
When you or someone else taps the sticker with a phone and there is no response, it's usually due to one of the following reasons. Please check them one by one:
1. The Phone's NFC is Turned Off (Most Common)
iPhone: For iPhone XR and newer models, NFC is automatically active for reading when the screen is on. For iPhone 7/8/X, you may need to manually tap the NFC reader icon in the Control Center.
Android: Pull down the notification shade or go to Settings -> Connections & Sharing (or a similar menu) and ensure the "NFC" toggle is on.
2. Incorrect Tapping Position
This is the second most common issue. Ensure you are using the NFC sensor area at the top back of the phone (near the camera) to tap the sticker. Try slightly moving or adjusting the angle to find the most responsive spot.
3. Obstruction or Interference
Thick Phone Case: Cases with metal decorations, magnetic rings, kickstands, or built-in cardholders can block the NFC signal.
The sticker is placed on a metal surface: As mentioned above, metal surfaces will disable the NFC sticker.
4. The Phone Model Doesn't Support NFC
Please confirm that the phone being used to read the sticker supports NFC. Some older or entry-level models may not have an NFC module.
5. Phone Responds Too Quickly or Too Slowly
The tap was too brief, and the phone was moved away before it could respond. We recommend holding contact for 1-2 seconds.
The phone might not respond immediately if it's locked, the screen is off, or it's lagging while running a demanding app. Please wake and unlock the screen first.
Recommended Sticker Placement on Your Phone
For the best user experience and to protect your sticker, we strongly recommend placing it on the lower half of the back of your phone.
Here’s why:
✅ Avoids the Wireless Charging Coil: Your phone's wireless charging coil is typically located in the center of the back. Placing the sticker there could interfere with charging efficiency, and the prolonged heat from charging could damage the sticker's chip over time.
✅ Prevents Interference with the Phone's Own NFC Antenna: A phone's built-in NFC antenna is usually at the top (near the camera). Placing the sticker on the lower half helps avoid signal conflicts with the phone's native NFC functions like Apple Pay or transit cards.
✅ Ensures Comfortable Grip and Use: When placed on the lower half, the sticker won't be frequently rubbed or covered by your fingers, whether you're holding the phone vertically or horizontally.
Pro-Tip: Before peeling off the adhesive backing, you can temporarily place the sticker on different spots on your phone's back. Tap it with your phone to find a position that is both convenient and highly responsive, then stick it on permanently.
