The existing anti-counterfeiting mark is usually printed or pasted with an anti-counterfeiting image, a code, a bar code or characters, such as a complex and beautiful holographic laser anti-counterfeiting label, on a required medium. However, the printing mark depends on a printing master (such as a printing head) which is made in advance, the finished anti-counterfeiting mark object for sticking needs to be prepared in advance when the mark is stuck, the information content of the anti-counterfeiting mark cannot be flexibly changed in the two modes, and the anti-counterfeiting mark is easy to forge and is easy to wear or damage.
