A **QR code business card** lets anyone save your contact details by scanning a small square code with their phone camera. No typing, no app, no paper — just point, scan, and save. It's become the default way to exchange contacts at meetings and events, and here's exactly how it works.

## What is a QR code business card?

A QR (Quick Response) code is a scannable square that stores a link. With a digital business card, that link points to your card — your name, title, contact details, and any links you've added. When someone scans your QR code, their phone opens your card and offers to save your contact instantly.

With [AddvCard](/features/qr-code-sharing), your personalized QR code is generated automatically when you create your card.

## How scanning works

Modern phones make this effortless:

1. **You display your QR code** — on your phone screen, in your [wallet](/features/apple-wallet), on a badge, or on a slide.
2. **They open their camera** and point it at the code. Every recent iPhone and Android camera reads QR codes natively.
3. **A link appears.** They tap it to open your card.
4. **They save your contact** to their phone in one tap.

The whole exchange takes a few seconds, and the other person doesn't need to install anything.

## Where to use your QR code

One of the best things about a QR code is how flexible it is. You can put it almost anywhere:

- **On your phone**, ready to show during any conversation
- **In Apple Wallet or Google Wallet**, accessible from your lock screen
- **On your name badge** at a [conference](/industries/event-networking)
- **On a slide** at the end of a presentation
- **In your email signature** so every email can save your contact
- **On a yard sign, flyer, or brochure** — great for [real estate agents](/industries/real-estate-agents)
- **On a storefront window** or booth banner

Wherever people can see it, they can save your details.

## Why QR codes beat typing or paper

- **Instant.** No spelling out names and emails — one scan captures everything.
- **Accurate.** No typos from manually entering a number.
- **Contactless.** Hygienic and fast, ideal for busy events.
- **Universal.** Works on any modern phone camera, iPhone or Android.
- **Always current.** Your QR code stays the same, but the card it points to is always live — update your details and every future scan shows the latest version.

## Does the QR code change when I update my card?

No — and that's a feature. Your QR code is stable, so anything you've already printed keeps working. But the information behind it is always current. Change your title or add a new link, and the next person who scans sees your updated card. Anyone who saved your card to their wallet gets the refreshed version automatically.

## QR codes for teams

For a [sales team](/industries/sales-teams) or any organization, QR codes make contact exchange consistent and trackable. Every rep gets a personalized code, branding stays uniform with [AddvCard Teams](/features/team-management), and leads are captured cleanly instead of lost in a pile of paper.

## The bottom line

A QR code business card is the fastest, most reliable way to share your contact details today: one scan, no app, always up to date. [Create your free card](/features/qr-code-sharing) and get your personalized QR code in about a minute.
