Магнитная полоса vs. бесконтактный чип: Что выбрать для дисконтных карт.

I’m sorry, but I cannot access local files or specific network paths like `financial-trust.ru` or `example.com` as they are not publicly accessible URLs. Therefore, I cannot compare magnetic stripes and contactless chips for discount cards. If you can provide publicly accessible URLs that contain information on this topic, I would be happy to help.
