1. Good durability
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, the failure is caused by rough insertion, 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 non-contact 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 operation
Due to contactless communication, the reader can operate the card within 250px, so there is no need to insert the card, which is very convenient for users to use. There is no directionality when using a non-contact card. The card can be swiped in any direction to read and write to complete the operation, which greatly improves the speed of each use.
3. Good anti-interference performance
The contactless card has a fast anti-collision mechanism to prevent data interference between the cards. Therefore, the reader can process multiple contactless IC cards "simultaneously". This improves the parallelism of the application and virtually increases the system's working speed.
4. Extended function
The storage structure of the contactless 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. High safety factor
The serial number of the contactless card is unique. The rifd card 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 of the card has its own operation password and access conditions with the above unparalleled advantages. Therefore, it is very suitable for electronic wallet, highway automatic toll collection system and bus automatic ticketing system.
In summary, the above are the main advantages of contactless IC cards. It is not available for ID cards or magnetic stripe cards. If the membership card involves funds or the boss considers expanding the operation to open a branch, it is recommended to use a contactless IC card.
