Download and print your QR code

Every card has its own QR code. It always opens your latest card, so you can print it once and keep changing your details.

The quickest way: go to Dashboard → Cards and tap the download button next to your card.

Or from the card itself:

1. Open your card

   Visit qudo.ink/c/your-link.

2. Show the QR code

   Tap QR code under your card.

3. Download it

   Tap Download QR for print.

Either way you get a sharp, black-on-white image that stays crisp at any size — from a sticker to a shop window.

Printing tips

• Size: at least 2 × 2 cm (about ¾ inch) on business cards, and 10 cm (4 inches) or more on posters and signs people will scan from a distance.
• Contrast: keep it dark on a light background. Avoid printing it on busy photos.
• Space: leave a little blank border around the code — it helps cameras find it.
• Test it: scan the printed proof with your phone before you order hundreds.

Ideas for where to put it

Van doors, invoices and receipts, restaurant tables, the salon mirror, the last slide of a talk, product packaging, event badges, and "for sale" signs.
