Not everyone you meet has a phone that taps. Your Cardia QR code covers the rest. Point a camera at it and your full profile opens, no app to install on either side.
A QR code on a paper card freezes whatever was true the day it was printed. Yours points at your live profile instead, so a new number, a new title, or a new company shows up the moment you save it. The code on the wall never changes.
One code, printed or on screen, wherever people already look.
Save it as a wallpaper. Someone asks for your details, you turn the phone around.
Sits under your name so every thread you are on can reach the full profile.
Print it once and stick it by the till. Walk-ins scan it without asking anyone.
Conference lanyards, expo stands, name tags. No app, no typing, no paper.
Drop it on your closing slide so the room can follow up while it is still fresh.
Flyers, packaging, receipts, a poster in a window. It all points to one profile.
