Program any NFC tag to share this card
You don't need branded hardware. A blank NTAG sticker, ring, or card works fine. Total cost: under $1 per tag.
What you'll need
- An NTAG215 sticker, card, or wristband. These are the standard chips used for digital-business-card products. Search "NTAG215 NFC stickers" on Amazon — ~$10 for 10 stickers. NTAG213 and NTAG216 also work; 215 has the best capacity/compatibility balance.
- An NFC writer app.
iPhone NFC Tools (free) on iOS 14+.
Android NFC Tools, or just use this site's built-in writer.
Write the tag
- Open NFC Tools → Write → Add a record → URL.
-
Paste the share URL:
https://card.alfrednaayem.com - Tap Write, then hold the tag flat against the back of your phone (iPhone: top edge; Android: middle/back).
- You'll get a confirmation when the write succeeds. Done.
Test it
Lock your phone, then tap the tag on the back. The card URL should pop up as a notification. Tap to open. On iPhone, NFC scanning is always on for iPhone XS and newer — no app needed by the receiver.
Make it stick
Peel and stick the NTAG sticker to the back of your phone, your laptop, the back of a paper card, or anything else flat and dry. Avoid metal surfaces unless the sticker is rated for metal — metal kills the read range.
Lock it (optional)
If you're handing the tag to someone, lock it so it can't be overwritten: in NFC Tools → Other → Lock tag. This is permanent — only do this once you're sure of the URL.
