What is the difference between id card and ic card?

The difference between id card and ic card: 1. Technical principle; 2. Security; 3. Application fields; 4. Cost and service life; 5. Development trend. Detailed introduction: 1. Technical principle. The full name of ID card is identification card. It is a low-frequency card with an operating frequency of 125KHz. The working principle of the ID card is to induce the magnetic field generated by the inductor coil on the card and the card reader, thereby transmitting Data, the full name of IC card is integrated circuit card. It is a high-frequency card with an operating frequency of 13.56MHz. The IC card has a built-in microchip that can store and process data, etc.

ID cards and IC cards are common cards in our daily lives. They are widely used in various occasions, such as access control, identification, payment, etc. However, there are some obvious differences between the two cards in terms of technical principles, security, application fields, etc.

1. Technical Principles

ID card: ID card is called identity card. It is a low-frequency card with a working frequency of 125KHz. The working principle of an ID card is that the inductor coil on the card induces the magnetic field generated by the card reader to transmit data. Since the ID card can only be read but not written, its security is relatively low.

IC card: The full name of IC card is integrated circuit card. It is a high-frequency card with an operating frequency of 13.56MHz. The IC card has a built-in microchip with the ability to store and process data. Unlike ID cards, IC cards can both read and write data, so they have higher security and flexibility.

2. Security

ID card: Since the ID card can only be read but not written, once the card information is copied, it cannot be changed or canceled. In addition, the ID card number is fixed and cannot be distinguished between different applications, which also increases security risks. Therefore, the security of ID cards is relatively low.

IC card: IC card uses cryptography principles to encrypt and decrypt data, which is highly secure. It can set different passwords and permissions to distinguish different application scenarios, effectively preventing information from being illegally copied and tampered with. In addition, IC cards are also anti-counterfeiting and anti-tampering, which greatly improves their security.

3. Application fields

ID card: Since the security of ID card is low, it is mainly used in some occasions where security requirements are not high, such as Access control, attendance, etc. In these occasions, the ID card only requires simple identification and does not require complex data processing.

IC card: Because IC card has higher security and flexibility, it is widely used in various occasions with high security requirements, such as financial payment, identity authentication, social security, etc. In these occasions, IC cards require complex data processing and security verification to ensure the security and accuracy of transactions.

4. Cost and service life

ID card: The production cost of ID card is relatively low because its structure is relatively simple. However, due to its non-writable nature, once the card information changes or needs to be reconfigured, a new card needs to be replaced, which increases the cost of use and management difficulty. In addition, ID cards have a relatively short service life and are easily damaged or invalidated by external factors.

IC card: The production cost of IC card is relatively high because its structure is relatively complex and it has a built-in microchip. However, due to its read-write characteristics, card information can be updated or reconfigured when needed, reducing usage costs and management difficulty. In addition, IC cards have a relatively long service life and have strong resistance to external interference.

5. Development Trend

With the advancement of science and technology and the improvement of security requirements, IC cards are increasingly used in various fields. In the future, with the rapid development of technologies such as the Internet of Things, cloud computing, and artificial intelligence, IC cards will have broader application prospects in terms of intelligence and personalization. Due to its technical limitations and security issues, ID cards may be gradually eliminated or restricted in use in certain specific fields.

In short, there are obvious differences between ID cards and IC cards in terms of technical principles, security, application fields, cost and service life, and development trends. When choosing which card to use, you need to consider comprehensive considerations based on actual application requirements and cost-effectiveness.
