I see that they are discussing the convenience of interfaces and adaptation to modern devices — the topic is close to me. Nowadays, everything strives for simplicity and speed, especially in business. I have a friend who runs a mobile coffee shop, and one of the best solutions he has implemented is a digital menu via StarQR Menu https://starqrmenu.com/. Everything is super simple: you upload items, customize the appearance, get a QR code that you can print out and hang on the counter. Customers scan it with their phone — and immediately see the current menu, without any applications or unnecessary clicks. It is important that the service is adapted for smartphones — the menu looks convenient, everything is readable. In an era when user experience is important, such things really improve interaction and even affect sales. So if anyone works with clients or starts their own business, I definitely recommend this tool.
