What are the Advantages of Contactless IC Cards Compared with Contact IC Cards?

The contactless IC card is a new type of smart card with the same functions as the contact ID card and IC card. It only needs no power supply, and the receiving antenna draws power from the magnetic field of the reader, and calculates the data and feeds it back to the reader. So what are the advantages of contactless IC card compared with contact IC card?

Compared with contact IC cards, contactless cards have the following advantages:

1. High reliability

There is no mechanical contact between the contactless IC card and the reader, which avoids various failures caused by contact reading and writing. For example, failures caused by rough insertion of cards, insertion of non-card foreign objects, and poor contact due to dust or oil. In addition, there is no exposed chip on the surface of the contactless card, and there is no need to worry about the chip falling off, electrostatic breakdown, and bending damage. It not only facilitates the printing of cards, but also improves the reliability of the cards.

2. Easy to operate and fast

Due to contactless communication, the reader can operate the card within 250px, so there is no need to insert the card, which is very user-friendly. There is no directionality when using a non-contact card. The card can be read and written in any direction to complete the operation, which greatly improves the speed of each use.

3. Anti-collision

The contactless card has a quick anti-collision mechanism to prevent data interference between the cards. Therefore, the reader can process multiple non-contact IC cards simultaneously. This improves the parallelism of the application and virtually increases the system's working speed.

4. It can be applied to multiple applications

The storage structure of the non-contact card makes it multi-purpose for one card and can be applied to different systems. Users can set different passwords and access conditions according to different applications.

5. Good encryption performance

The serial number of the contactless card is unique. The manufacturer has cured this serial number before the product leaves the factory and cannot be changed. A two-way authentication mechanism is used between the contactless card and the reader. That is, the reader verifies the legitimacy of the IC card, and the IC card also verifies the legitimacy of the reader. The contactless card must be authenticated with the reader three times before processing, and all data is encrypted during the communication. In addition, each sector in the card has its own operation password and access conditions, so it is very suitable for use in electronic wallets, highway automatic toll collection systems and bus automatic ticketing systems.
