An NFC business card is a plastic, metal or wooden card with a tiny chip inside; when someone holds their phone near it, your page opens at once. It is the physical side of a [digital business card](https://wslat.net/en), combining the look of a traditional card with the speed of a link.

Before you buy, some questions deserve answers: which material suits you, which chip to choose, what gets written on the card, and whether you can change the destination later. This guide answers them step by step.

> **Key takeaways**
> Choose the material by use: plastic is economical, metal is premium, wood is distinctive.
> The chip only needs to hold one short link.
> Write a fixed link, lock the chip, then change where it points from your dashboard.
> Add a QR code to the card as a backup.

## How does an NFC business card work?

Inside the card is a chip and an antenna with no battery. When a phone comes close, its electromagnetic field powers the chip, which sends what is stored on it. The technology is explained in [what is NFC](https://wslat.net/en/blog/what-is-nfc).

[Wikipedia](https://en.wikipedia.org/wiki/Near-field_communication) gives the maximum range as about 4 cm, so a tap is always deliberate. A card in your pocket is never read.

## Materials: plastic, metal or wood?

**NFC card materials compared**

| Material | Look | Strengths | Notes |
| --- | --- | --- | --- |
| PVC plastic | Clean and standard | Affordable, flexible, easy to print | Best for bulk distribution |
| Metal | Premium and heavy | Durable and memorable | Can weaken the signal; confirm a shielding layer |
| Wood or bamboo | Natural and warm | Distinctive and eco-minded | Suits crafts and restaurants |
| Sticker or stand | Simple | For tables and windows | Stick on a suitable surface |

Metal makes a strong impression, but a tag stuck directly on metal needs a ferrite shielding layer to work. Ask your supplier before ordering.

## Chips: what matters

Chips differ in memory, response speed and phone compatibility. Tag memory typically ranges from 96 bytes to about 8,192 bytes, and a short link needs far less.

- **Memory:** one link does not need a large chip.
- **Compatibility:** choose a reliable chip that Android and iPhone both read.
- **Locking:** a chip that can be made read-only prevents overwriting.
- **Quality:** buy from a supplier that tests cards before shipping.

## What gets written on the card?

The chip stores one link in the standard NDEF format. Do not write all your details on it; write only your page address. The web page carries the buttons, photos and updates.

Keep the printed side simple: your name or logo, a line such as "Tap your phone here", and a small backup QR code. Do not cram in information; the page will show everything.

## Linking the card to your page and changing the destination

In Wslat the card carries a short link of yours that points to your page. Because the destination is stored in the dashboard rather than on the chip, you can later switch it to another page or a seasonal offer without reprogramming the card.

1. Create your page and get its link.
2. Order the card, or write the short link to your own chip.
3. Test the card on both an Android phone and an iPhone.
4. Lock the chip against writing if it supports that.
5. Redirect the destination from the dashboard when needed, and watch the taps.

If the page does not appear when someone taps, check [how to turn on NFC](https://wslat.net/en/blog/how-to-turn-on-nfc); the feature may be off on their phone.

## Security and privacy

The card holds only a public link to a page whose content you choose. It does not make payments or carry your banking details. The full picture is in is NFC safe.

## Tips before you buy

- Order one sample and test it on several phones before the full batch.
- Make sure the printed design does not cover the antenna area with metal or conductive ink.
- Match the design to your brand; for the bigger picture see [digital vs paper business cards](https://wslat.net/en/blog/digital-vs-paper-business-cards).
- Plan a fallback: a QR code for phones without NFC.
- If buying for a team, assign each card to a person so you can reassign it.

Done well, an NFC card becomes the most memorable part of your [digital business card](https://wslat.net/en) and costs you nothing extra each time your details change.

## Who is an NFC card for?

It suits anyone who meets people face to face and wants their details to stay on the other person's phone afterwards. Material and design vary with the audience.

- **Doctors and consultants:** an elegant card opening the booking page and location.
- **Sales reps:** one card each, opening the catalogue and WhatsApp.
- **Restaurants and cafes:** a table stand opening the menu or review link.
- **Salons:** a card at the mirror opening the gallery and booking.
- **Real estate agents:** a card opening the listings page and calling the owner.

The card is only a door; it is the page behind it that does the selling, so start with a clear page.

## How many cards do you need?

Start small. Try one card per person who meets customers, then watch the taps in the dashboard before ordering a large quantity. If customers prefer scanning, print a bigger QR code; if they tap a lot, order more cards.

When a new employee joins or one leaves, there is no need to order new cards: you can point the card to the new person's page from the dashboard. That saves time and cost and keeps your branding consistent.

## FAQ

**Does an NFC card need a battery or charging?**
No. The chip draws power from the reading phone at the moment of contact.

**Can I change the link after printing?**
If you wrote a short link tied to your Wslat page, yes. You change its destination from the dashboard without touching the card.

**Does it work with iPhone and Android?**
Yes with modern phones that support NFC. For others, the printed QR code does the job.

**How many links can the card hold?**
In practice one link is best, since your page gathers all the others.

**Can water or bending damage the card?**
Good plastic handles daily use, but sharp bending can break the antenna, so avoid it.
