I hardly think these are "secret" codes. QR code establishing conditions allowing Russian soldiers to safely surrender to the Ukrainian.

"SCAN TO SURVIVE Bizarre secret codes being handed to fleeing Russian troops on ‘surrender cards’ to help them escape war alive"

From The Sun ^ | 12:55, 14 Sep 2022 | Anthony Blair the tip from Freeper.

"UKRAINE has been handing out 'surrender cards' to Russian soldiers containing secret codes with advice on how they can return home alive, reports have claimed. The cards feature a message in Russian for Vlad's invading forces, as well as a QR code on the back with links to further information on how soldiers can surrender to Ukraine"

Indeed surrendering on the battlefield can be a very risky business. Your adversary may not be in any position for a variety or reasons to take prisoners. Especially you do not want to try to surrender to an armored vehicle of any type. The crew of the vehicle cannot detail one man to guard you and at the same time cannot just let you go. You might might get shot dead on the spot!!
