Another example is that in some countries it’s necessary to take a test before visiting
museums, restaurants, and even grocery stores. Residents and tourists in France, Germany,
and other countries plan their leisure time with a
PCR test QR code in their phone or
printed versions of the test results in their pocket. There is no point in leaving the house
without them.
Thus, you can print test results and take them everywhere with you or you can bypass the
paperwork and use the digital version of the test. An electronic document has the same legal
force and is in no way inferior to a paper one; on the contrary, it makes things easy.
