What the card needs
Use your public display name, a readable phone number if appropriate, a short profile URL, and a large high-contrast QR code.
Where the QR should lead
Send the scan directly to your stable public driver profile, not a temporary campaign or link that may expire.
Prepare for printing
Use the print-ready file, keep key content inside the safe area, extend background color through the bleed, and test the QR at actual size.
Share with context
Offer the card to people you meet and passengers you already serve; let the quality of the ride support the invitation.
