The card
Credit-card size. Printed both sides. An NFC chip sealed inside, and a QR code on the back that does the same job for any phone that would rather look than tap.
Have a look at one
Pick a kind of card and a colour scheme. The back changes with the front — the QR is drawn from the same palette, every time.
For one person
Your name, what you do, and a mark that looks like you. The kind of card you hand to someone at the end of a conversation.
These sample codes really do scan. Point a phone at one — it opens this site. On a real card it opens your page.
Colour
These four are where most cards start. If you have brand colours, we use those instead — the QR is drawn to match, not to fight.

About that QR code
A QR code does not have to be ugly. There is enough error correction inside one that it can carry colour, rounded modules and a distinct eye shape and still read first time — which is exactly what we do, in the colours of the card it is printed on. What we do not do is push it past the point where a scanner hesitates. Every code is tested before it is printed.
Your 4-digit code lives inside the QR as well as under it, so activating a card is a scan and a tap rather than four digits typed by hand.
