Fiber laser marking is mainly used in mobile phone card marking in the telecommunications industry and IC card marking in urban public utilities. Its specific application areas cover public transportation, rental, rail transit (metro), water supply, heating, gas, garden landscape, A wide range of areas such as digital communities, road and bridge tolls, and parking lot management.
A smart card (IC card), also known as a smart card, a smart card, an integrated circuit card, and an IC card, refers to a portable card plastic that is affixed or embedded with an integrated circuit chip. It is formed by embedding an integrated circuit chip with a microprocessor and a large-capacity memory on a plastic substrate, and its shape is very similar to that of a normal*. Smart cards have emerged with the development of semiconductor technology and the increasing demands of society for information security and storage capacity. Today, smart cards have become a new star in the information society. Common smart cards include telephone IC cards, identity IC cards, and some transportation tickets and memory cards.

China's IC card industry is developing at an alarming rate. Especially in the past two years, China's annual card issuance exceeds 100 million. The application areas of IC cards cover telecommunications, social security, *, banking, tax, public transportation, and highway cards. , fuel cards and many other industries. With the expansion of the scale of IC card applications, the packaging, printing and labeling business of cards has developed into industrial production.
With the development of the IC card industry and the improvement of the requirements for card making, the printing method of the card has gradually shifted from ink printing and thermal transfer to laser printing.
Comparison of fiber laser marking and other card making technologies
Laser marking is replacing traditional card-making technology with more and more applications due to its unmatched advantages such as permanent marking and no consumables. In addition, due to the rapid development of laser technology and the market demand for laser products with high output power, small size and low maintenance, the laser module integrated in the card issuing machine has been pumped from the lamp pumping machine and diode pump. The standard machine gradually developed into a Fiber Laser Marking Machine.
The fiber Laser Marking Machine uses a computer controlled laser to etch characters, patterns or barcodes on the surface of the card, and has the advantages of more beautiful marking, no consumables, and maintenance-free.

Card-making efficiency of fiber laser marking machine
The fiber laser marking machine is integrated on a small card issuing machine. For example, a 10W fiber laser marking machine integrated on the PT3080 can mark up to 750 cards per hour.

Materials for fiber laser marking applications
Fiber laser marking can mark a wide range of materials, including PVC, PC, high temperature plastics, Teslin, ABS, PET, PET-G, PET-F and other materials.
Application examples of fiber laser marking in the IC card industry
Fiber laser marking is mainly used in mobile phone card marking in the telecommunications industry and IC card marking in urban public utilities. Its specific application areas cover public transportation, rental, rail transit (metro), water supply, heating, gas, garden landscape, A wide range of areas such as digital communities, road and bridge tolls, and parking lot management. The following are some specific application areas and marking examples of fiber laser marking.

Figure 4: Mobile phone card marked with a 30W fiber laser marking machine
Figure 4 shows the marking effect on a mobile phone card with a 30W fiber laser marking machine. The mobile phone card laser marking content is mainly 128, 39 barcodes and numbers. Generally, there are certain requirements for the readable level of the barcode. Marked with a 30W fiber laser marking machine, each card uses a marking time of less than 1 second (depending on the material). Of course, for the same marking content, the higher the average output power of the laser, the shorter the time required for marking.

The application of smart cards has covered many fields of today's social economy. According to the survey of international professional organizations, there are currently billions of smart cards being used internationally, and the application of smart cards in large and medium cities in China is becoming more and more popular. In some places, the local government even built the city card or citizen card project as a kind of "people's heart project" to build it. It has also played a very good effect in real life and has played an active role in promoting the overall harmonious society. Promotion. Therefore, with the development of the smart card industry, the application of laser technology will become more and more extensive.
