We are looking for a technological solution for applying datamatrix and QR codes to our products. We are mainly coding the metal zincplated surfaces (galvanized, painted), on which it is necessary to apply the coding in such a way as not to damage the protective layer of the metal and not "expose" it, so that this does not subsequently lead to corrosion due to long-term storage in the open air and under the influence of weather conditions. As far as we know, there are two technologies for applying codes to metals without damaging it: 1) the drop-jet method (including with nano-ink and subsequent coating of the code with a ceramic adhesive layer that strengthens the code and protects it from external influences and aggressive natural conditions; 2) application with a fiber optic laser using a special adhesive paste (TherMark, CerMark).
If you can offer any other technologies for high-quality application of codes to metal surfaces (without damaging it), please let us know and offer options.

We are interested in mobile (portable) systems that can apply codes both to metal surfaces (as indicated above), as well as to other materials such as: Plastic, cardboard, wood, paper, glass, etc.
Mobile (portable) systems are mostly cosidered.

Additionally, we are also interested in:
1) code readers (scanners)
2) printers for printing stickers with data matrix and QR with the function of generating digital codes in graphic

Please let us know if you can offer us any high-tech solutions and equipment according to our requirements...
