Programmable NFC
SiNE CARD II supports NFC for information sharing and product verification. You can read or write standard NFC content, or use the built-in verification mode to verify the product.
NFC
SiNE CARD II supports programmable NFC content in NDEF format.
Use a compatible NFC writing app, such as NFC Tools, to write or update the content on SiNE CARD II. After writing, read the card again to check the saved content.
For sharing with both iPhone and Android users, we recommend using an HTTPS website link. Internet access is required to load the webpage.
Writing standard NFC content does not affect the product verification function.
How to Use NFC
Can I open a website without an NFC reader app?
Yes. On iPhone XS/XR and later, unlock your iPhone and hold its top edge near the NFC area on SiNE CARD II. When the card contains a supported website link, tap the notification to open it. A separate NFC reader app is not required.
Why does my iPhone show nothing after I write text, contact details or Wi-Fi information?
iOS does not automatically open these record types through background NFC reading. This does not necessarily mean the write failed.
Open a compatible reader app, such as NFC Tools, and use its Read function to view the saved data. Reading a record does not guarantee that iOS will perform its intended action, such as joining a Wi-Fi network.
How to Use NFC
How do I read the NFC content?
Enable NFC in your phone’s settings, unlock the phone and hold its NFC area near SiNE CARD II. Follow any on-screen prompt to open the content or choose an app.
The result depends on the stored record type, your phone, Android version and installed apps.
Will every record written with NFC Tools open automatically?
No. Website links, text, contact details and Wi-Fi records may be handled differently. Some content requires a compatible app or additional confirmation.
If nothing appears, open NFC Tools and use its Read function to check the saved data. For content intended for both Android and iPhone users, use a website link and test it on both platforms.
How to Use NFC
Make sure SiNE CARD II is powered on. Press the button three times quickly to enter NFC verification mode. The status LED will flash three times and the buzzer will beep twice.
Within three minutes, hold an NFC-enabled phone near the card. The phone will open verify.sinetag.com and display the product verification result.
After verification is completed, SiNE CARD II automatically exits verification mode.
If the card is not scanned within three minutes, start verification mode again.
