Do people need an app to open a digital business card? Web apps, browsers and what happens on their phone
By Online Business Cards Editorial Team | Published | Updated | Explainers
No app is needed on either side: your card is a web page that opens in the phone's own browser. Here is what happens on the other person's phone, where it can go wrong, and how to test it.
The short answer is no. A digital business card is a web page. When someone scans your QR code or taps your link, it opens in the web browser that is already on their phone, so there is nothing to download, no account to create and nothing for you to install on their behalf. This guide explains what actually happens on the other person's phone, where it can go wrong, and how to test it yourself before you rely on it.
What happens when someone opens your card
- They scan your QR code or tap your link. You might show the code on your phone, print it on a sign, or send the link by text, WhatsApp or email.
- Their phone opens the address in its browser. On an iPhone that is usually Safari; on Android it is usually Chrome. If they opened your link inside WhatsApp or LinkedIn, it may open in that app's built-in browser instead, which works the same way.
- Your profile loads. They see your name, photo or logo, what you do and the buttons you have chosen, such as call, email, book or send an enquiry.
- They save you or take the next step. Pressing the save contact button gives their phone a contact file with your details, which they can add to their contacts in a couple of taps.
That is the whole journey. Because it is a normal web page, it works the same way whether they are a client, a supplier or someone you met at an event.
Which phones it works on
- iPhone. The built-in Camera app has read QR codes since iOS 11. They point the camera at the code and tap the link that appears.
- Android. Most recent Android phones read QR codes in the camera app or through Google Lens. On some older models the option is in the camera settings, or they may need a QR reader.
- Laptops and desktops. A QR code is awkward to scan from a computer, so for people at a desk, a plain link works better. Our guide to adding your card to your email signature covers that.
- Any phone without a working camera. Send the link by text or WhatsApp. It opens in the browser just the same.
If someone struggles to scan, do not keep trying in front of them. Ask for their number and text them the link. Our guide to the six ways to share a digital business card explains when each method works best.
Saving your details to their contacts
Opening your profile is not the same as keeping your details. The save contact button is what puts you in their phone, so it is worth checking exactly what it sends.
- Use the international format for your mobile, starting +44, so the number works for contacts outside the UK.
- Check your name and job title appear the way you want, for example "Priya Shah" rather than "priya.shah".
- Try it on both an iPhone and an Android phone. The contact screen looks different on each, and you want both to look right.
If the details that arrive are wrong, update the profile in the profile editor and test again. The QR code and link stay the same.
When there is no signal
Be realistic about this: a digital business card is a web page, so the other person's phone needs mobile data or Wi-Fi to open it. You may read claims that some digital cards "work offline". We do not make that claim for ours.
In practice, poor signal is easy to work around:
- Text them the link. It arrives when their phone reconnects and they can open it later.
- Show your profile on your own phone. If it has already loaded on your screen, they can read your details or photograph the screen.
- Keep a few printed cards with your QR code. For basements, rural venues and busy exhibition halls, a small run of paper cards is a sensible backup. Our QR code size and placement guide explains how large to print the code.
Is it a web app? Can it go on a home screen?
A progressive web app, often shortened to PWA, is a website that can be added to a phone's home screen and then opens much like an app. The part that matters for a business card is simpler: your card is a web page, so nobody has to install anything to open it, and anyone who wants it on their home screen can add it.
Yes, in the same way as any web page. On an iPhone, open your profile in Safari, press Share and choose Add to Home Screen. On Android, open it in Chrome, open the menu and choose Add to Home screen or Install, depending on the version. That is useful for you, so your own card is one press away when you want to show it. You can also keep it in your phone's wallet, as explained in our guide to Apple Wallet and Google Wallet.
You do not need to ask anyone else to do this. For most people, saving your contact is the step that matters.
Making it open quickly
Most people will open your card on a phone, often on mobile data, so a lighter profile is a better profile.
- Resize photos before you upload them. A headshot does not need to be the full size your camera took it at.
- Keep the gallery and documents to what people actually need. You can always link to your website for more.
- Put the important details near the top, so people see them even before everything else has loaded. Our guide to laying out your profile covers what to put first.
Making it easy to read for everyone
Because your card opens in the browser, people can zoom in and use the accessibility settings they already rely on, such as larger text or a screen reader. You can help by:
- writing button labels that say what they do, such as "Book a call" rather than "Click here";
- never putting your phone number or address only inside an image, where screen readers and search cannot read it;
- choosing a template with clear contrast between text and background.
How to test your card in five minutes
- Scan your QR code with an iPhone and an Android phone, if you can borrow one.
- Open your link from a text message and from WhatsApp.
- Press save contact on each phone and check what arrives.
- Press every button: call, email, map, booking and any links.
- Turn Wi-Fi off and open it on mobile data to see how quickly it loads.
Our list of common digital business card mistakes covers what to fix if anything goes wrong.
Web page or app: what the other person has to do
Digital card (web page) | Separate app
Download needed | No | Yes
Account needed | No | Often
Works on iPhone and Android | Yes, in the browser | Only if both versions exist
Saves your details to contacts | Yes | Depends on the app
Which plan you need
Sharing works the same way on both of our one-off plans. Brand Presence (£45, one-off) gives you the profile with your details, social links, documents, gallery, testimonials, templates and analytics. The Business Plan (£90, one-off) adds tools for what happens next, such as enquiries, bookings, contact leads, forms, a CRM and a card scanner. Profiles are built and hosted by our platform partner. You can compare them on our plans.

Frequently asked questions
Is a digital business card a progressive web app?
A digital business card is a web page that opens in the phone's own browser, so nobody has to install anything. Like other web pages, it can be added to a home screen, which is the main thing people mean by a progressive web app.
Does the person I share my card with need to download an app?
No. Your card is a web page, so it opens in the browser already on their phone. They scan your QR code with the camera or tap your link.
Do I need an app to share my card?
No. You can show your QR code on your phone, copy your link into a message, or add it to your email signature. You edit the profile itself in the profile editor.
Does a digital business card work without internet?
The other person's phone needs mobile data or Wi-Fi to open it. If signal is poor, text them the link so they can open it later, or keep a few printed cards with your QR code as a backup.
Will it work on older phones?
Any phone with a web browser can open the link. Some older Android phones need a setting changed or a separate reader to scan QR codes, so sending the link by text is the simplest option.
Can people save my details to their phone?
Yes. The save contact button gives their phone a contact file with your details. Test it on an iPhone and an Android phone to check your name, number and email arrive correctly.
