However, over time, its application has spread to various sectors such as food and pharmaceuticals, satisfying consumer demands for transparency in production processes.
Positive acceptance by industries and its growing popularity led to the free release of the QR code for public use in 2002, with the intention of making it accessible to a greater number of people.
Today, the QR code has become an indispensable tool for companies of all sizes and sectors, as well as in the educational field. It took a decade for its global popularity to become established and it was after 2012 that it became widely spread in areas such as digital marketing and advertising.
