A vCard QR code holds your full contact details, so one scan offers to save your name, company, job title, phone, email, website and address into a phone address book. It is the fastest way to hand over details at an event, and it belongs on the back of a business card, an email signature print-out or a trade-show banner. Fill in only the fields you want to share — every extra field adds data, so a leaner card scans more easily from a distance.
