The pandemic brought with it the need to reduce physical contact, both between people and with objects. With the aim of maintaining tourists' and residents' health and safety, destinations sped up the digitalisation processes for all kinds of items. Maps, leaflets and catalogues were replaced by online versions.

As a result, one of the elements that grew exponentially was the use of QR codes. The fact that the vast majority of people use smartphones allows them to access any particular location on the Internet quickly and easily: with just a click, tourists can download any information without needing to physically come into contact with any objects.
The digitalisation of information services has a wide range of benefits, but there are two that stand out:

• Lower costs, as physical informative material no longer needs to be preserved or edited.
• Lower environmental impacts, through a lower use of paper.

To make QR codes as efficient as possible, their locations must be optimal, in a visible spot and at a height of between 1.2 and 1.5 metres so that anyone can access them, regardless of their physical or mental condition.
With regard to the digital accessibility of the content provided by QR codes, it must meet minimum standard AA established by the World Wide Web Consortium (W3C) in its Web Content Accessibility Guidelines (WCAG).
