Use Cases
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).
