QR codes guide for Smart business cards and connected products

Keep it simple

The more elaborate the QR code, the more challenging it is for users to scan them. We print simple black and white QR codes on connected products at the point of manufacture. 


Please be aware that fraudsters can replace a QR code easily in public spaces. We recommend using NFC for instant payments. However, QR is great for quick access to advertising and content. 

The ideal size of a QR code should be 1cmx1cm with 20mm space around it to ensure scanning is successful.
