Increasingly, restaurants, food outlets, snack-bars, pubs, etc. are changing-over from physical menus that are given to customers to online menus that customers access directly using their mobile phones using a QR Code. Not surprising as a QR Code-accessed menu has the following advantages:

 No need to print the menus on every price update.
 Anyone with a smartphone can browse the menu using QR Code scanner. Never run out of menus.
 No need for passing around greasy paper menus. No need for disinfecting them.
 Easily update and manage menu items and prices. No need for reprinting paper menus.
