Advantage Analysis of RFID Card

The RFID card is in a non-contact operation state when reading and writing, which avoids the misoperation of reading and writing caused by poor contact, and avoids the influence of dirt, oil pollution and other adverse external environment on reading and writing card.

Easy to operate, fast - RFID cards adopts wireless communication mode, and there is no direction requirement in use, so it is very convenient to use.

Anti-collision - there is a fast anti-collision mechanism in the RFID card, which can prevent data interference between cards, so the terminal can process multiple cards at the same time.

Convenient for multi-use in one card: There are many partitions in the RFID card, and each partition has its own password, so different partitions can be used for different applications to achieve multi-use in one card.

Compared with contact IC card, RFID card has the following advantages:

High reliability - there is no mechanical contact between the card and the reader, avoiding various faults caused by contact reading and writing. For example: malfunction caused by rough card insertion, insertion of non-card objects, dust, oil pollution, etc.

There is no bare chip on the card surface, and there is no need to worry about falling off, electrostatic breakdown, bending damage and other issues of the chip.

Easy and fast operation - Because of non-contact communication, the reader can operate the card in the range of 1cm-10cm, so it does not need to do the plug-and-play work like IC card. When using the non-contact card, there is no directionality, and the card can skim over the reader's surface in any direction, which greatly improves the speed of each use.

Anti-collision - there is a fast anti-collision mechanism in the RFID card, which can prevent data interference between the cards, so the reader can process several contactless RFID cards at the same time.

The application range is wide-- the memory structure of RFID card makes it have multi-purpose in one card. It can be used in different systems and users can set different passwords and access conditions according to different applications.

Encryption performance is good - the serial number of the RFID card is unique. The manufacturer solidifies the serial number before the product leaves the factory and it can not be changed any more.

The two-way verification mechanism is used between the RFID card and the reader, that is, the reader verifies the validity of the RFID card, and the RF card also verifies the validity of the reader. Before processing, the card and the reader should authenticate each other three times, and all data in the communication process are encrypted. In addition, each sector of the card has its own operating password and access conditions.
