On cards, the back carries a QR code that opens your Card2Tap profile — the same place a tap opens. Card2Tap places it for you in templates and AI designs.
- Size: at least 15 mm wide, so phones scan it easily.
- Contrast: dark code on a light background works best. Avoid low-contrast colours.
- Quiet zone: keep clear space around the code — no text or artwork touching it.
- Inside the safe area, away from the edge.
The preview shows a sample code. When your order is produced, Card2Tap puts the link of the card it’s printed on into the QR code.
