About QR Codes

QR (Quick Response) codes are two-dimensional barcodes that can store text, URLs, contact info, Wi-Fi credentials, and more. They were invented in 1994 by Denso Wave for tracking automotive parts and are now used everywhere from restaurant menus to payment systems.

Error correction allows QR codes to be read even when partially damaged or obscured. Level L recovers ~7% of data, M ~15%, Q ~25%, and H ~30%. Higher levels make the code larger but more resilient — use H if you plan to overlay a logo.

Capacity depends on the data type and error correction level. A Version 40 QR code (the largest) can hold up to 4,296 alphanumeric characters or 2,953 bytes of binary data at the lowest error correction level.

Common uses: URLs (https://...), plain text, email addresses (mailto:...), phone numbers (tel:...), SMS (smsto:...), Wi-Fi credentials (WIFI:T:WPA;S:network;P:password;;), and vCards for contact sharing.

What is a vCard QR code?

A vCard QR code encodes contact information in the vCard (VCF) format inside a QR barcode. When scanned, the recipient's phone prompts them to save the contact — including name, phone numbers, email, company, title, and address — directly to their address book without manual entry.

Common use cases

vCard QR codes are widely used on business cards to make digital contact exchange effortless, at trade shows and networking events for quick introductions, on employee badges for visitor check-in systems, and on email signatures or personal websites as a modern alternative to downloadable VCF files.

Frequently Asked Questions

What information can a vCard QR code contain?

A vCard QR code can include your full name, phone numbers, email addresses, company name, job title, website URL, and physical address. The more fields you add, the denser the QR code becomes.

Can I update a vCard QR code after printing?

Static vCard QR codes cannot be changed after creation since the data is encoded directly in the image. If your details change, you will need to generate and print a new QR code.
