## How it works

### Build your digital card

Add your name, role, links, and contact details once in ConnectMachine. Your digital business card is ready to share in every format, with no design work and nothing to print.

### Share by QR, link, or tap

Show your QR code, send a link, or tap phones together. Whoever you meet opens it instantly in their browser, so there is nothing for them to download first.

### They save you in one tap

Your details drop straight into their phone contacts. Because the card lives online, any edit you make shows up the next time they open it.

## What makes it work

### No app required to receive

The person you meet never installs anything. They scan or tap, view your card in a browser, and save it. That removes the friction that kills most contact shares.

### QR code and link in one

Share the same card as a scannable QR on your phone or lock screen, or as a link in an email signature or chat. One card, every channel.

### Always up to date

Change jobs or numbers and update your card once. Everyone who reopens it sees the current version, so your details never go stale in someone else's phone.

## FAQ

### How do I share my contact without making people download an app?

Share your ConnectMachine card as a QR code or link. The other person opens it in their browser and saves your details, with no app install on their side.

### What is a digital business card?

A digital business card is an online version of your contact details that you share by QR code, link, or tap instead of handing over paper. It updates any time and never runs out.

### Do QR code business cards work on any phone?

Yes. Any modern phone camera reads the QR code and opens your card in the browser, so it works across iPhone and Android without special software.

### Can I still share my card if there is no signal?

You can show your QR code offline, and the person can save your core details as soon as they open it. A live connection just lets them see your latest updates.
