Packaging has an important information and communication function: What is the shelf life of the product, which ingredients were used, which allergens and which nutrients are included? These and other details are mandatory for food packaging. Digital codes placed invisibly on the packaging open up a wide field of information and dialogue possibilities for manufacturers with their customers. As a printing specialist with experience in the use and implementation of these codes, Nyco Flexible Packaging, based in Kirchberg/Switzerland, offers the key to almost unlimited added value in B2C communication. Through the use of invisible codes, the smartphone becomes a tool for optimally addressing consumers and providing them with information. Even when it comes to providing information for elderly people or people with handicaps, this is easier to do via digital codes, for example through read-aloud functions or the enlargement of the font. This means an important step towards accessibility.
