Frequently Asked Questions
Frequently asked questions about the vCard QR Code Generator: What belongs in a vCard? How big should I print the QR code?
What belongs in a vCard?
A vCard can contain name, phone numbers, email addresses, company, job title, address, website, and social profiles. All fields are optional – you can include exactly what you want to share.
How big should I print the QR code?
For reliable scanning, we recommend a minimum size of 2×2 cm. For business cards, 2.5×2.5 cm usually works well. The more data in the QR code, the larger it should be printed.
Which file format should I use?
For printing, we recommend SVG (vector graphic) – it can be printed at any size without loss of quality. PNG works well for digital use (email signatures, websites).
Does the QR code work on all phones?
Yes. vCard QR codes work on iPhones and Android devices. The camera app recognizes the QR code and offers to save the contact.
Is my data stored anywhere?
No. Everything happens directly in your browser. No data is sent to a server, stored, or shared.
Can I customize the QR code colors?
Yes. You can customize the QR code color and background. Just make sure there is enough contrast so the code remains easy to scan.
How do you capture contact details with a QR code?
You create a vCard QR code here with your contact details. Anyone who scans the code with their phone camera gets the option to save the contact right away – no typing, no form. That’s how contact data capture via QR code works: one scan, contact in the address book.
Can I create a QR code for my business card for free?
Yes. The static QR code for business cards is free and works without an account. You can download it as PNG or SVG and use it on printed business cards, flyers, or email signatures.
What is the difference between QR code, vCard, and VCF?
The vCard is the contact format, VCF is the file extension, and the QR code is the scannable representation of it. This tool generates a vCard QR code that phones recognize as a contact.
Can I change the QR code after printing?
A static vCard QR code stores the contact details directly in the code and cannot be changed after printing. For editable contact details after printing, use a dynamic QR code.
