A dog tag is an informal name of a metal piece used in military forces for identification of soldiers. Nowadays they can be used for recognizing company by placing its name, product, photo, etc. Dog tags are made from the highest quality materials – stainless steel or, in a cheaper version, iron covered with copper and later an optional plating (nickel, silver, brass, gold) or aluminium. As a marking technique we use engraving, laser, printing and embossing with or without colour. Ball chains of any length or metal chains with rings are also available.
