vCardr

vCardr turns any contact into a full-screen QR code another phone can scan in seconds — no app required on the other end, no account, no cloud. Pick a contact and vCardr renders a standard vCard QR code you can hold up for someone to scan with their camera. Their phone offers to save the card straight to Contacts. That's it. • Show your own card or anyone from your address book • Works entirely offline — your contacts never leave your device • Nothing is uploaded, tracked, or stored anywhere else • Clean, high-contrast codes that scan fast, in light or dark • Received a card? Open it and save it with one tap • Home-screen widget shows your code without opening the app — StandBy included vCardr reads a contact only to draw its QR code on your screen. It transmits nothing and keeps nothing off your device.
