MDM-12 plays an important role in many industrial and commercial fields, and it has become one of the most widely used technologies in recent years. This article describes the application field and working principle of MDM-12.

What is MDM-12?

MDM-12 is a type of magnetic card reader that can be used to read and write information stored on magnetic cards. It was developed by the company Metrologic Data Systems (MDS) and was first introduced in the late 1990s. MDM-12 can read and write magnetic cards that are encoded with ISO7816-2 standards, as well as some proprietary formats. MDM-12 is also capable of reading and writing EMV (Europay, Mastercard, and Visa) cards that comply with the EMV standards.

Application Field of MDM-12

Because of its small size, ease of use, and compatibility with a wide range of card formats, MDM-12 is used in a variety of applications. Commonly, these include access control, point of sale, loyalty programs, financial transactions, and many more. The most popular applications of MDM-12 are card-based security systems, which can be used in a variety of buildings such as office buildings, airports, hospitals, and more. MDM-12 is also used in businesses to track and monitor employee time and attendance. Additionally, MDM-12 is commonly integrated with self-service checkout systems in supermarkets and other retail stores.

Working Principle of MDM-12

The principle of operation of MDM-12 is based on the magnetic stripe. When a card is inserted into the MDM-12 card reader, the magnetic stripes on the back of the card interact with small magnets in the reader. The reader then converts the magnetic signals into electrical signals, which are then sent to the system\'s processor. The processor then interprets the information in the magnetic signal and stores it in a database. The information stored in the database is then used to control access to the system, or to validate the transactions.

MDM-12 card readers are relatively easy to install and use, making them popular for a variety of applications. In addition, they are also relatively inexpensive compared to other types of card readers, which makes them a popular choice for many businesses. Furthermore, MDM-12 card readers also feature advanced security measures such as encryption and authentication. This makes them suitable for applications where security is of paramount importance.

Conclusion

In conclusion, MDM-12 is a versatile and secure magnetic card reader that is used in a variety of applications. It is capable of reading and writing many different card formats, and its small size and ease of use make it attractive for many different applications. Additionally, its advanced security measures make it ideal for secure applications. As such, MDM-12 is an important technology in many different industrial and commercial fields.
