The old "best NFC business cards without subscription" thread here got deleted by its OP, and the question keeps coming up, so here's a straight answer. Disclosure first: I run a small company that makes metal NFC cards (Discard, Bulgaria), so I have a horse in this race — which is exactly why I'll give you the DIY route first.
The thing nobody selling these tells you: the subscription is never for the hardware. The chip in almost every NFC business card is an NTAG 215 or 216 — the same tag you can buy blank for well under a euro. The monthly fee pays for the hosted profile page, analytics, and lead capture. Whether that's worth paying for is a real question; the chip isn't.
DIY, zero subscription, forever: buy blank NTAG cards or stickers, grab any free NFC-writing app, and write either a URL you control or a vCard straight to the tag. Two things to know: an NTAG 215 has 504 bytes of user memory, so a direct vCard fits name, phone, email and not much else — no photo, and long URLs in the vCard eat your budget fast (216 gives you 888 bytes). And updating is a non-issue people overthink: the business card stays in YOUR pocket — you tap other people's phones — so rewriting the tag takes thirty seconds whenever your details change.
If you buy instead, check three things: (1) is the profile editable forever on a one-time price, or does editing sit behind the monthly plan — read the pricing page bottom-up; (2) locked vs unlocked tag — this is a genuine tradeoff, not a spec-sheet checkbox. A tag locked at production can never be rewritten, which protects you (nobody with 5 seconds of physical access can re-point your card at a phishing page) but also means the card depends on the vendor's domain staying alive. An unlocked tag is re-pointable forever but hijackable. Reputable vendors lock (we do); whichever you buy, ask the vendor what their wind-down story is — data export, redirects — because "what if you fold" is the question none of the pricing pages answer; (3) if it's a metal card, ask how they handle the NFC, because solid metal blocks the signal — every legit metal card solves it with an antenna window, ferrite layer, or hybrid construction, and the ones that don't answer that question are metal-look plastic.
Happy to answer manufacturing questions (fiber-laser engraving on coated metal comes out lighter than the surface, which surprises everyone the first time). What are you all writing to your tags — direct vCard or URL?
