A new digital normal
Summer is an ideal season to discover new corners and hospitality establishments. Since the onset of the pandemic, many places have replaced their classic specialty menus with QR codes, which allow access to menu information by simply scanning them. This system, which on the surface seems harmless, can carry certain risks, especially if used in unknown establishments.
The rise of QR codes
QR codes were born in Japan in 1994, developed by the company Denso Wave, part of the Toyota group, to improve the location of parts in warehouses. The pandemic triggered its use in hospitality and commerce, allowing access to information without physical contact. Although restrictions have eased, many restaurants continue to use them as a cost-effective solution to display their menus. In addition, public administrations also use them in various places, such as monuments, to provide additional information.
Potential risks of QR
QR codes are often placed in high-traffic places, making it easy for cybercriminals to replace them with malicious links. To avoid this, it is essential to be vigilant and take precautionary measures to not allow a simple scan to compromise our device. In restaurants, codes are frequently posted on tables, making them susceptible to being replaced with counterfeit codes. Given this, many establishments choose to use supports such as metal, glass or wood, which are more difficult to manipulate.
Measures to avoid inconveniences
URL verification
Before scanning any QR code, it is crucial to check the URL to which it directs us. If it shows signs of tampering or does not seem trustworthy, it is best not to continue.
Precautions with financial information
Special care must be taken if at any time financial information is requested from us through the QR. It is advisable to distrust and validate the legitimacy of the page before offering any sensitive data.
Check the status of the QR code
Another useful tip is to inspect the physical QR for signs of tampering. If we observe that the code has been altered or replaced, it is preferable not to scan it.
Prevent app installations
It is never a good idea to install applications via a QR code, as they could contain malicious software. It is always better to download applications from official stores.
It is important to follow these simple precautions to enjoy the summer without a malicious QR ruining your vacation. A little attention will allow us to avoid problems and enjoy the specialties that the new establishments offer us.
