Contact details
Generated as vCard 3.0, which imports more reliably into iOS Contacts, Android and Outlook than 4.0. A long contact makes a dense QR code, so if the readability check complains, trim the address or the note.
Preview
Enter at least a name or company and the QR code will appear here.
Held in the hand. Keep the content short, because a long URL makes this too dense.
Rendered at 300 dpi for the physical size, at 85 × 55 mm. The destination is printed in small type beneath the code so a failed scan is not a dead end.
Kept in this browser so you can reopen and edit it later. Nothing is uploaded.
Design
The blank margin scanners use to find the code's edges. Four is the specified minimum, so the slider does not go lower.
