Are QR Business Cards Safe? Where Your Details Are Stored
3 min read
How safe a QR business card is depends on where your details live. With some services, your details sit on a public profile page on a company's server and the QR code only points to that page. With a vCard QR code, the details are inside the code itself. Here's the difference and how to choose.
Two kinds of QR business card
| Profile-link QR | vCard QR | |
|---|---|---|
| Where are the details? | On a profile page on the provider's server | Inside the QR code |
| Changing details later | Edit the profile | Create a new QR code |
| Internet needed to save the contact | Yes, to open the profile page | No, the details are in the code |
| Scan statistics | Often collected | Not collected |
| If the service shuts down | The link may stop working | The code keeps working |
Both have their place. What matters is knowing which one you use and what that means for your details.
If you use a profile-link QR code
- The profile page has a public address. Anyone with the link can open it.
- Read the privacy policy. Find out how long your details are kept and who they are shared with.
- Check the subscription. With some services the profile closes when the subscription ends, and the QR code on your printed cards stops working.
Know the limits of a vCard QR code
With a vCard QR code your details aren't stored on a server. That doesn't make them secret, though.
- Anyone who scans the code sees the details in it. Don't put anything in the QR code that you wouldn't print on your card.
- Changed details need a new code. When your number or title changes, you need a new code and new printed cards.
- Too many details make the code dense. Adding lots of fields makes the QR pattern busier and harder to scan in small prints.
Tips for safe use
- Use your work contact details rather than your home address or personal mobile number.
- Leave out anything you don't want to share.
- Before printing, scan the code with your own phone and check what gets saved to contacts.
- If you use a profile-based service, protect your account with a strong password.
