QR Code Business Card
A QR code business card encodes a vCard (contact information) directly into the code, so scanning it saves your name, phone, email and website straight into someone's phone contacts — no manual typing, no exchanging paper.
This works because vCard is a standardized plain-text format phones already know how to interpret the moment they scan it; the QR code is just carrying that format instead of a URL. It's one of the most practical everyday uses of a QR code, since it removes the single biggest source of friction in networking — someone actually typing your details into their phone later (or forgetting to).
There's a design choice worth making deliberately: encode a vCard directly (so scanning immediately offers to save your contact, no internet connection required), or encode a URL pointing to an online profile or link-in-bio page instead. The vCard route works completely offline and saves contact details in one tap; the URL route requires a connection at scan time but can link to a richer page with a bio, portfolio links, or social profiles beyond what a vCard field structure supports.
Placement and sizing matter more on a business card than almost any other QR use case, since the available space is small and the card is often handled and viewed at close range. A modest size in a corner, styled to match the card's color scheme, tends to read as an intentional design element rather than an afterthought — oversized or default black-and-white codes dominating the layout are the most common business-card-specific design mistake.
Because a standard business card is handled at very close range, a smaller printed code than most other use cases require — often well under the general 2×2 cm minimum guideline — can still scan reliably, since the viewing distance is naturally short. Testing at the actual intended handling distance remains worthwhile before a full print run, the same as any other printed QR use case.
