Digital Business Card

How a digital business card works

Three steps, and the third is the one that matters.

1. You build a profile with your name, job title, company, phone, email, WhatsApp, website and social links.
2. The profile is hosted at its own URL, and you get a QR code that points at it.
3. Someone scans the code, your profile opens in their browser, and they tap Save Contact to write you into their phone.

The recipient installs nothing. There is no app, no account and no sign-up on their side — which matters, because anything you ask a new contact to install is a reason for them not to bother.

How to create your digital business card

1. Sign in or create an account. The profile is hosted, so it needs somewhere to live.
2. Add your name, title, company and photo.
3. Add your contact methods: phone, email, WhatsApp, website.
4. Add your social and professional links.
5. Publish. You get a profile URL and a QR code.
6. Download the code as SVG for print or PNG for screens, and place it wherever customers and professional contacts are most likely to see it.

What to put on a digital business card

Less than you think. A card that lists eleven ways to reach you gets none of them used, because you have handed the decision back to the recipient.

Include, in this order:

Your name and what you actually do. Not your internal job title — the thing a stranger would understand. "Commercial roofing, London" beats "Regional Director". A photo. It is the single strongest recall aid on the card and paper never had it. One primary contact method, made obvious. Pick the channel you actually answer. A second method as a fallback. Your company and website. The two or three social links that do professional work for you. LinkedIn for most people. Instagram if your work is visual. GitHub if you write code. A single call to action if you have one — book a call, view portfolio, get a quote.

Leave out: every social network you have ever joined, your fax number, a personal mobile you do not want strangers holding, and your home address.

Digital, paper, or NFC

These are not competing religions. They do different jobs.

The honest read. Paper still wins on reliability and on the physical ritual — in some industries and some countries, handing over a card is the etiquette and skipping it reads as careless. A digital card wins on everything after the handshake: it cannot run out, it cannot be out of date, and it puts itself into the recipient's phone instead of into their pocket to be thrown away later.

NFC is a hardware layer over the same idea. A tap is smoother than a scan when it works, but it needs a phone with NFC reading enabled and held in the right place, and you are paying per physical card. A QR code costs nothing and works on any phone with a camera.

The setup most people should actually run: keep a small stack of paper cards with your QR code printed on the back. Hand over the paper, let them scan it if they want the digital version. You cover both preferences and both failure modes.

Digital business card or vCard QR code?

These get confused constantly, and the difference is the reason this product exists.

A vCard QR code encodes your contact details directly inside the QR pattern. It is static: no hosting, no internet needed, and it works forever. It is also frozen. Change your number and every printed code is wrong.

A digital business card encodes a short URL that points at a hosted profile. The details live on the profile, so you can change them at any time and every code you have ever handed out updates with them.

There is also a technical problem with static vCard codes that nobody mentions until it bites. A full vCard is a lot of data. Name, title, company, two phone numbers, an email, a website and an address can run to a few hundred bytes, and adding a photo pushes it far higher. QR Code capacity is defined in ISO/IEC 18004, and while a Version 40 symbol can hold up to 2,953 bytes in byte mode at the lowest error correction level, using that capacity means a very large number of very small modules. The result is a dense, fragile code that fails on a small print size, on cheap stock, or in poor light. A hosted profile URL is around thirty characters. It produces a small, clean, robust code that scans from a business card corner every time.

So: use the free vCard QR code generator when you want a static, permanent, offline code and your details will not change. Use a digital business card when they will.

Update your details without reprinting

Change your phone number, your job title, your company, or your photo, and every QR code you have ever printed or shared now points at the new version. The code does not change because the URL does not change.

This is worth real money to anyone who moves roles, changes numbers, or works somewhere with frequent restructures. It is also the answer to the oldest problem in business cards: the drawer full of cards that became wrong the moment someone changed jobs.

The trade-off, stated plainly: this only works while the profile URL keeps resolving. A hosted card is a dependency in a way a paper card is not. That is true of every digital business card provider, and it is a fair question to ask any of them — including this one. Ask what happens to your printed codes if the service ends, and whether you can point your own domain at the profile.

Where to put your QR code

The card is only worth what its distribution is. Most people publish once and stop.

The back of your paper business card. The highest-value placement, because it catches the people who still want paper and converts them anyway. Your email signature, as a small code or a link. Your phone lock screen or wallpaper, so you can show it across a table without opening anything. Your laptop lid, your phone case, your water bottle. Sales people who do this get scanned at conferences without ever starting the conversation. Your conference badge, or a sticker on it. Your video call background, bottom corner, large enough to scan from a screen. Your shop window, van livery, or site hoarding if you are a trade. Your CV, if you are job hunting. Your presentation's closing slide. Your invoice and quote templates.

Print size and design

Print at 2 to 2.5 cm for a business card corner, read close up in the hand. Go to 3 cm or more for a conference badge read at arm's length, and 8 cm or more for a window or poster read across a room.

Leave a clear margin of at least four modules on every side. ISO/IEC 18004 specifies this quiet zone and scanners use it to locate the symbol. Cropping it to fit a layout is the most common reason a code that looked fine in the design file will not scan on the printed card.

Keep dark modules on a light background and keep contrast high. Download SVG for print, because it is vector and scales without loss. Use PNG for screens. Avoid JPG, whose compression softens the module edges that scanners read.

Who this is for

Sales teams. The card that updates when territories change, and scan data that tells you which events produced conversations.

Estate and letting agents. Photo, phone, WhatsApp and current listings behind one code on the board, the brochure and the car.

Freelancers and consultants. One link holding your portfolio, your booking calendar and your contact details, without paying for a website you will not maintain.

Trades. A code on the van and the quote form, going straight to your phone and WhatsApp. This is the segment where WhatsApp matters most and where competitors barely look.

Conference and event networkers. No card stock to run out of at four in the afternoon on day two.

Corporate teams. Consistent cards across a department, updated centrally when the branding or the phone system changes.

Job seekers. A profile holding your CV, your LinkedIn and your portfolio, on a code you can put on the CV itself.

Is your profile public?

Yes. A hosted profile lives at a URL, and anyone with that URL can open it. That is what makes it shareable, and it is also the thing to be deliberate about.

Put on it what you would put on a card you hand to a stranger, because functionally that is what it is. Use a work number rather than a personal one if you would not give the personal one out. Leave your home address off. If you would rather the profile did not turn up in search results, check whether you can set it to be excluded from indexing — being shareable and being searchable are different things, and a good tool lets you choose.

Do digital business cards actually work?

Sometimes the honest answer is a qualified yes.

They work when the person you are meeting is already holding their phone, when you say "scan this" rather than leaving it to be noticed, and when the profile loads fast and has an obvious Save Contact button. They work extremely well as a follow-up layer, in an email signature or a video call background, where the recipient is already on a device.

They work badly when there is no signal, when you hand someone a code with no explanation, when the profile takes eight seconds to load, or when the recipient is of a generation or an industry where producing a phone instead of a card reads as informal. They also do nothing at all if you never point anyone at them.

Paper business cards are not dead. What has changed is that paper is no longer the only option, and it is no longer the best one for anything that changes. Use both, and let the recipient choose.
