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.
How to Use NFC
Hold an NFC-enabled iPhone or Android phone near the NFC area on SiNE CARD II. The phone will detect the stored NFC content and display the available action.
Depending on the content stored on the card, NFC can open a website, display text, or share contact information.
How to Use NFC

Within three minutes, hold an NFC-enabled phone near the card. The phone will open verify.sinetag.com and display the product verification result.
