Contactless IC card, also known as radio frequency card, is a new technology developed in recent years. It combines radio frequency identification technology and IC card technology to solve passive (no power in the card) and contactless technology. question.
Compared with contact IC cards, non-contact IC cards have the following characteristics:
(1) High reliability. Because there is no mechanical contact between reading and writing, various failures caused by contact reading and writing are avoided; and there is no exposed chip on the surface of the non-contact IC card, and there is no worry about chip falling off, electrostatic breakdown, and bending damage.
(2) Easy to operate. Contactless communication enables the reader to operate the card within a range of 10 cm, and the non-contact IC card is non-directional when in use, the card can be swept across the surface of the reader in any direction to complete the operation, which is convenient and Increased speed.
(3) Anti-collision. The contactless IC card has a fast anti-collision mechanism, which can prevent data interference between cards, and the reader can process multiple contactless IC cards "simultaneously".
(4) Can be adapted to a variety of applications. The characteristics of the non-contact Ic card memory structure make it suitable for a multi-purpose card, and different passwords and access conditions can be set according to different applications.
(5) The encryption performance is good. The serial number of the contactless IC card is unique, it has been solidified before leaving the factory, and there is a two-way verification mechanism between it and the reader.
