What are the advantages of IC cards over magnetic cards?

The non-contact IC card replaces the magnetic card is the development trend of the smart card industry. Why can IC cards gradually replace magnetic cards? What are the advantages of IC cards compared with magnetic cards? IC cards have unique advantages in terms of storage capacity, security, and convenience. The following are the details of the advantages of Dejian Intelligent Technology compared with IC cards and magnetic cards.

What are the advantages of IC cards over magnetic cards?

1. In terms of storage capacity:

The IC card can store megabytes, and the magnetic card can only store a few hundred bytes. The IC card has internal memory such as RAM, ROM, and EEPROM, which can store various information such as text, sound, graphics, and images, and the storage area can be divided. There are different levels of access.

2. In terms of encryption:

IC cards can be encrypted, magnetic cards cannot be encrypted. The magnetic card has no control circuit, so its internal data reading and writing cannot be safely controlled. The reading technology is also sequential and mechanical. The IC card can control the circuit to read and write its internal data. The erasure control and reading technology are random. . The encrypted IC card itself has a secure password. If you attempt to access the data illegally, the card will self-destruct and cannot be read or written.

3. Dependence on the network:

IC cards can be used offline, magnetic cards cannot be used offline. When using a magnetic card, ensure the strong real-time nature between the terminal and the host. Once the host or network fails, the entire system will be paralyzed. The IC card can store a large amount of data and is controlled by logic circuits. All operations are all performed during use. It is completed independently by the terminal, which reduces the real-time and sensitivity requirements of the computer network in the application environment.

What are the advantages of IC cards over magnetic cards?

4. In terms of service life:

The magnetic card has a short service life, and generally has a life span of one to five years, while the IC card can reach more than ten years.

5. Anti-interference:

Magnetic cards are inferior in anti-magnetism, anti-static, waterproof, etc., and the magnetic strip cannot be rubbed randomly, while IC cards are strong in these aspects, as long as the chip should be kept clean.

6. Anti-counterfeiting aspects:

Magnetic cards are easy to counterfeit, while IC cards themselves have extremely strong logic encryption, making forgery difficult.

7. Convenience of use:

IC card reading and writing equipment is simpler and more reliable than magnetic card reading and writing equipment, cheaper to build, easier to promote, and easier to maintain.
