In the late eighties, with the rapid development of laser technology, a light weight, easy control and stable operation (time between failures for up to 20,000 hours), excellent beam quality "CO2 RF laser" has successfully entered the commercial phase, and quickly applied to the production line high-speed flow of product identification engraving area. To the late nineties, the developed countries, high-speed line laser marking system has been widely applied to electronic components, automotive, food, chemical, communications equipment and other products of the production line, and its non-polluting, non-consumables , low failure, anti-counterfeiting unparalleled advantages such as large-scale alternative to ink coder. Laser inkjet printer in China, Guangdong, Hong Kong, Taiwan and other regions also known as laser coder.

"FLYMARK (flight code) or laser coder," is a kind of laser marking machine, but its application is not limited to marking on the product name, specification, production date, expiry date, batch number and other functions. Laser marking technique is unique, which can be not altered, anti-fake, thus has strong security features. This function is to combat counterfeiting and protect the interests of consumers, providing another effective means.

Laser marking machine has no material consumption, which not only saves users a lot of materials, when the ink coder expenses (ink coder average annual direct consumption of each ink and solvent less than 25,000 RMB), a decrease of social resources consumption, but also supplies the complete elimination of the use of chemical pollution on the environment.
