Casinos can use QR codes for a variety of applications. For instance, placing one on a game machine can provide easy access to instructions. They can also be placed around casinos – at the front desk and on promotional materials – to give quick mobile access to event promotions, contactless payments, and customer feedback.

When used in these ways, QR code technology has the potential to enhance the guest experience by making services more accessible and engaging (ultimately boosting casino profits).
