It can be the case that not only the people sitting next to it will want to scan the QR Code, but also people from other seats as well. For example, if you use a QR Code on a print ad inside a train, you have to think about where it will be scanned from. When designing a QR Code to be used for a minimum distance scan, you have to also consider the placement. The size needed for a short distance QR Code scanĪlthough there is a minimum size QR Code of 2 x 2 cm (0.8 x 0.8 in), QR Codes be made as large as you need as long as you use high-quality images so that the pixels don’t become too blurred. ![]() They can just scan the QR Code and are automatically connected to the appropriate digital content or payment platform. Furthermore, they’re also convenient for users, because people don’t need to try to find links or a separate payment system. The key point here is that all of the elements from the above list can be used for contactless marketing and mobile payments due to QR Codes. Digital platforms (social media, emails, and landing pages).Ī QR Code on a catalog requires a short scanning distance.Public transit posters or advertisements.Mail, invoices, receipts, and paperwork.Display signs or table tents for mobile payments.QR Codes that are often scanned at short distances include: The only requirement is that the QR Code is a minimum of 2 x 2 cm (0.8 x 0.8 in), otherwise, a QR Code scanner could have trouble scanning it and viewers could have difficulty reading it. Unlike NFC technology that has a radius of 4 cm (1.5 in), QR Codes have a minimum radius of 25 cm (10 in), which then scales up depending on the size of the QR Code. QR Codes can easily be scanned from a short distance. ![]() Source: Scanning QR Codes from a minimum distance QR Codes enable convenient and contactless mobile payments.
