Magnetic card

A magnetic card is a card-like magnetic recording medium that uses magnetic carriers to record characters and digital information for identification purposes or other purposes. The magnetic card is made of high-strength, high-temperature-resistant plastic or paper-coated plastic, and can be damp-proof, wear-resistant and have certain flexibility. It is easy to carry and uses more stable and reliable. For example, the bank card we use is the most common type of magnetic stripe card.

Magnetic cards are easy to use, cheap, and widely used. They can be used to make credit cards, bank cards, subway cards, bus cards, ticket cards, and telephone cards; electronic game cards, tickets, air tickets, and various transportation charge cards. Today, on many occasions, we use magnetic cards, such as eating in the cafeteria, shopping in the mall, making bus calls, making phone calls, entering controlled areas, and so forth.

From May 1, 2017, the bank will fully close the magnetic stripe transaction on the chip magnetic stripe composite card.


The difference between magnetic card and IC card

Magnetic cards and IC cards are the two most commonly used card types in the current information society, and they are "regular customers" in our wallets. China's annual issuance volume has exceeded 200 million. What is the difference between the magnetic stripe card and the IC card? See Table 8 for comparison instructions.

Card Description Advantages Disadvantages

Magnetic stripe card The core part of the magnetic stripe card is the magnetic stripe stuck on the card. The typical magnetic stripe card is the widely used bank card. The biggest advantage of magnetic stripe cards is that they are easy to read and write, low in cost, and easy to promote. The disadvantage is that it is easily worn out and interfered with by other magnetic fields. As a bank card, its security is relatively poor. Many people in life have encountered the problems of magnetic stripe failure after repeated use or being scratched by a hard object such as a key.

IC Card The IC card is an IC chip that is first packaged in a small piece of copper and then embedded in a plastic card. The typical IC card is our social security card. The information of the IC card is stored in the chip, which is not susceptible to interference and damage, and has high safety and long service life. On the other hand, the IC card has a large capacity of information, much higher than the magnetic stripe card, and it is easier to store personal data and information. However, compared with magnetic stripe cards, IC cards have high costs and are not easily replaced after being damaged or lost.

The magnetic stripe card is a veteran in the card industry. It has the longest use time and the largest number of uses. With the development of informatization and electronic technology, magnetic stripe cards have gradually faded out of the stage of history due to the disadvantages described above.

A magnetic card is a magnetic recording medium card. It is made of high-strength, high-temperature resistant plastic or paper-coated plastic, which is moisture-proof, wear-resistant and has a certain degree of flexibility. It is easy to carry and uses more stable and reliable. Typically, one side of the magnetic card is printed with explanatory information, such as the direction of the card insertion; the other side is provided with a magnetic layer or magnetic stripe, with 2-3 tracks to record the relevant information data.

Magnetic stripe track

There are 3 tracks on the magnetic stripe. Track 1, track 2, and track 3 are read and write tracks and can be read or written during use.

Track 1 can record numbers (0-9), letters (A-Z), and other symbols (such as brackets, separators, etc.), and can record up to 79 numbers or letters.

The characters recorded on tracks 2 and 3 can only be numbers (0-9). Track 2 can record up to 40 characters, and Track 3 can record up to 107 characters.

The magnetic strip is a thin layer of material (also called a pigment) composed of aligned and oriented iron oxide particles. The resin adhesive is tightly bonded together and adhered to a non-magnetic substrate medium such as paper or plastic.

Magnetic strips are essentially the same as tapes or disks used in computers. They can be used to record letters, characters, and numbers. The magnetic card is formed by firmly integrating the plastic or paper by adhesion or heat sealing. The information contained in the magnetic stripe is generally larger than the long bar code. The magnetic strip can be divided into three independent tracks, called TK1, TK2, TK3, TK1 can write up to 79 letters or characters; TK2 can write up to 40 characters; TK3 can write up to 107 characters. Because magnetic cards are low-cost, easy to use, easy to manage, and have certain security features, their development has been supported by many world-famous companies, especially national government departments for decades, making the application of magnetic cards very popular and widespread in national life. All aspects. It is worth mentioning that the widespread use of the banking system for decades has led to a great development in the popularity of magnetic cards.
