Program an NFC chip

Each prize card has a permanent URL on prizecardvault.com at /c/…. Write that full URL to an NTAG213, NTAG215, or NTAG216 chip, then embed the chip in the physical card. A phone tap opens the 3D vault page for that card.

  1. 1. Copy the card URL below.
  2. 2. Open an NFC writer (NXP TagWriter, NFC Tools, or the Write chip button on Android Chrome).
  3. 3. Write a URL / URI record. Do not add extra path segments.
  4. 4. Confirm with a tap. The phone should land on that card’s 3D view.
