QR-код должен быть с одноразовой проверкой на подлинность. Это разве трудно сделать ? Тогда подделки исчезнут сами собой.

The significant differences between fake spark plugs (in my case, this is DENSO SC20HR11 IRIDIUM) from the original are as follows. The central electrode did not have a laser-welded iridium washer/cylinder, and the side electrode had a stamped imitation of a "welded" resistance welding disk. These differences between the fake spark plugs and the genue spark plugs can only be seen using a binocular microscope.
