Nothing to reprint when details change
The chip stores the permanent smart link, not a frozen copy of your current phone number or job title.
Tap instead of type
An NFC business card can be cheap, reusable and completely ordinary hardware.
You do not need to buy a proprietary “smart business card”. Anyone can make one from an ordinary writable NFC card or sticker, often for only a few tens of pence per card in bulk, then write the permanent My Contact Profile link themselves.
Why it is useful
One physical card can serve you for years.
No proprietary hardware lock-in
Use an ordinary compatible NFC Forum Type 2 card or tag. The profile service and physical card are separate choices.
Fast in face-to-face meetings
A tap can open the profile immediately, with QR printed on the same card as a visible fallback.
NFC source analytics
The NFC programming link carries an NFC source marker, so NFC opens can be counted separately from QR opens.
Hardware cost
Blank unprinted NFC cards are the low-cost option.
As a practical buying guide, blank unprinted NFC cards often start from around $0.50 USD each on average, and can be cheaper in larger quantities. The expensive part is usually custom printing, packaging or buying a branded finished product — not the NFC chip itself.
- For normal profile sharing, choose 13.56 MHz NFC Forum Type 2 hardware with a genuine NXP NTAG213, NTAG215 or NTAG216 chip.
- Avoid unrelated 125 kHz access-control cards; they are not the same as normal phone-readable NFC profile cards.
- White, black and wood-look cards are mainly finish choices. The important compatibility point is the chip and NFC standard inside.
Compatible blank cards
The same profile works with simple blank cards in different finishes.
These are the common blank card styles people usually buy first. The visible finish can change, but the recommended chip families stay the same.
White PVC NFC card
The most common low-cost option. Best when you want a clean blank card, your own printed sticker, or direct printing later. Recommended types: NTAG213, NTAG215 or NTAG216.
Black PVC NFC card
A more premium-looking blank card without changing how the profile works. Useful when you want a sleek minimalist finish. Recommended types: NTAG213, NTAG215 or NTAG216.
Wood-style or wooden NFC card
A natural-looking premium option for creative or boutique brands. The finish is different, but the same NFC logic applies. Recommended types: NTAG213, NTAG215 or NTAG216.
Other compatible formats
You are not limited to full-size cards.
The same permanent profile link can also live on stickers, mini tags and other compact NFC formats. These are useful if you want to upgrade an existing card, badge, desk sign or product insert.
Adhesive NFC stickers
An easy way to convert an existing plastic card, badge holder, sign or product box. Recommended types: NTAG213 or NTAG215, with anti-metal versions when the surface is metal.
Mini NFC tags and discs
Small round tags, desk dots and compact tokens use the same profile link idea in a smaller format. Recommended types: NTAG213 or NTAG215 on NFC Forum Type 2 hardware.
Mixed NFC formats
It is normal to use more than one format: a full-size card for meetings, a sticker for packaging, and a small tag for displays or events. The same profile can support them all.
Real-world tap moment
The best explanation is seeing a card open a live profile in seconds.
A printed NFC card feels familiar, but the tap opens something much more useful than ink on paper: a live profile that can stay current.
Choosing a compatible NFC card
NTAG213 is the simple choice for My Contact Profile.
The NFC chip only needs to store your permanent My Contact Profile address. NTAG213 has enough memory for that normal use, so there is usually no reason to pay more just for extra chip memory. NTAG215 and NTAG216 also work if you already have them.
- Look for 13.56 MHz, NFC Forum Type 2, NDEF-compatible cards or tags.
- NTAG213 is the recommended starting point. NTAG215 and NTAG216 are also compatible.
- If the tag will sit directly on metal, choose an anti-metal version. If you plan to print on the card, make sure the card stock matches your printer.
Programming takes minutes
How to put your profile on an NFC card.
Use Write to NFC card on Android
On an NFC-capable Android phone with Chrome 89 or later, Profile Builder can write your permanent NFC link directly to the card with no separate NFC app.
Use NFC Tools on iPhone or as a fallback
On iPhone, install NFC Tools, then copy the NFC programming link from Profile Builder and write it as a URL / URI record.
Test before locking
Read the card with another NFC-capable phone. Only make the tag read-only after you know it opens the correct permanent My Contact Profile link.
Best physical card: NFC + printed QR.
NFC is quick when the reader knows where to tap. QR is visible and works as a fallback. Putting both on the same card gives people a choice without changing the profile behind either one.
Questions
Frequently asked questions
Do I need to buy an NFC card from My Contact Profile?
No. V1 intentionally supports ordinary compatible writable NFC cards, tags and stickers instead of proprietary hardware.
Does the NFC card contain all my contact details?
No. The recommended setup writes one permanent HTTPS smart link. Your actual profile data stays online, where you can update it later.
Can I rewrite the card?
Most blank NFC tags are rewritable until you deliberately lock them. Do not make a tag read-only until you have tested the link.
