With the popularization of smart phones, SIM cards, or phone cards, are used more and more as the core component of mobile phones. In addition, the current mobile phone supports dual-card dual-standby. Although it provides convenience for users, there is always a security risk when a person has multiple calling cards. Therefore, the state has introduced relevant policies to require the real-name system of SIM cards to regulate the market order. And, if you look closely, you will find that there will be a long string of numbers and letters on the back of each SIM card, that is, the ICCID integrated circuit card identification code of the mobile phone card, which is the "identity card" of the phone card.

So how are these numbers marked? I will introduce it to you in detail today. The traditional SIM card mark is printed by ink jet printer, but because the ink is easily worn on the surface of the SIK card, the identity information is easy to lose, which brings trouble to the traceability of the SIM card. Therefore, due to the improvement of the process, a laser marking process was introduced in the production process of the SIM card, and a laser marking machine was used to mark the SIM card.

SIM card laser marking machine, also known as CCD identification marking machine, is a highly intelligent, automatic identification positioning and marking model, which can optimize the production process, reduce manual placement time, and have high marking efficiency. It is widely used in the fine marking of 3C electronics, medical industry, communication industry and other products
