Many years of testing

After a lot of tests, it is the only solution to have durable QR-Codes, a maximum duration of 2 years with the other solutions and with in addition a loss of readability.
As a reminder, the Qr-code is placed outside without any protection, it must face extreme conditions, sun, very high temperature difference, humidity, rain, salt and freezes.

The last test which took 18 months at the same place.

Unable to find any solution other than replacing the QR-code systematically after 18 months, one day I came across a small company specializing in laser marking on stainless steel support, Lacier.

For information, authorizations were requested from the Town Hall before for the test of qr-codes at remarkable points of the town.
Since 2019, the test QR-Code in the middle of nowhere has been scanned at least 5 times a day, especially on weekends and in all languages!
