Field of the Invention The present invention relates to a two-dimensional bar code, and more particularly to a QR code formed on a metal surface and a method of manufacturing the same. [Prior Art] As a new information storage and transmission technology, 2D barcode is widely used in many fields such as commodity identification, security and e-commerce. The two-dimensional bar code uses a certain geometric pattern to record the data symbol information in a black and white pattern distributed in a two-dimensional direction according to a certain rule; in the code preparation, the "0" and "1" which constitute the internal logic foundation of the computer are skillfully utilized in the code preparation. The concept of a bit stream uses a number of geometric shapes corresponding to the binary to represent the literal value information, and is automatically read by the image input device or the photoelectric scanning device to realize automatic information processing. Common international standard 2D barcodes include PDF417, Data Matrix, Maxi Code and QR Code. Among them, Quick Response Cod.e (Q'R Code) is the most widely used. QR code has super high speed. Omni-directional (360 degrees) reading characteristics, can effectively represent Chinese characters, has been widely used in many industries, QR code symbol is a square array composed of a series of small square information blocks, expressed by the gray-scale changes of light and dark “0” or “Γ”, when the QR code is applied to automobile manufacturing, aircraft manufacturing, weapon manufacturing and all mechanical products, it is required to express the QR code on the metal surface or the plastic surface, but the surface is engraved and bright. Compared with the dark pair, the printing surface is low, the QR code is difficult to recognize and is prone to distortion. Therefore, a QR code with high stability, readability and easy identification is urgently needed to overcome the above drawbacks.
