The data can be related to the code of origin, vehicle model, and the product's own bar code. It is formed around the circumference at different positions. The same tooth shape can be combined for each car, and each car has a code. Each car has different widths and widths of different shaped hard bar codes. The difference is calculated in micrometers, and the code can be 8 digits or more. Ten million times or more is not repeated, and it is not common between cars; the special-shaped restriction column or the core special-shaped restriction column that is connected with the steering system linkage can be cylindrical, triangular, pentagonal and corresponding Special-shaped hard bar code sockets are matched with cylindrical, triangular, and pentagonal slots.
