QR codes used by hotel to offer extra services
scan QR codes for various different purposes. Some services have been developed to allow customers to use the QR codes as their room keys. These barcodes are very inexpensive to generate and their uses are limited only to the imagination of the mobile marketing team at the hotel. There is even a unique hotel room in the Netherlands that was created by Dutch fashion designer, Antoine Peters, who covered the room’s entire décor in quick response barcodes.
