br Philips card has the following advantages
br Philips card has high reliability
br There is no mechanical contact between the Philips card and the reader, which avoids reading and writing due to contact. Various faults may occur, such as rough card insertion, foreign matter inserted into the card, dust or oil, resulting in poor contact, etc. There is no exposed chip on the surface of the proximity card. The microchip is encapsulated with a protective layer. There is no need to worry about chip shedding, static electricity, water immersion, ultraviolet radiation, folding and distortion. This not only facilitates the printing of the card, but also improves the reliability of the card. In addition, the data on the card can be read and written more than 10,000 times, and the storage period can be more than a year.
br Philips card operation is convenient and fast
br Due to non-contact communication, the reader can operate the card within a range of up to centimeters, so there is no need to insert or remove the card, and it is very convenient to use. convenient. The proximity card has no directionality when used. The card can be swiped across the surface of the reader in any direction. The transaction time is no more than seconds, and the operation can be completed, which greatly improves the speed of use.
br Philips card anti-collision
br There is a fast anti-collision mechanism in the proximity card, which can prevent data interference between cards. Therefore, the reader can process multiple cards at the same time. Proximity card, which improves the parallelism of applications and virtually improves the system working speed.
br Can be suitable for a variety of applications
br Proximity cards are usually divided into multiple storage areas such as r. The characteristics of the storage structure make it possible for one card to be used for multiple purposes. It can be applied to different systems, and different passwords and access conditions can be set according to different applications to truly realize an all-in-one card.
br Philips card has good encryption performance
br The serial number of the proximity card is unique. The manufacturer has solidified the serial number before the product leaves the factory and cannot be changed. A two-way verification mechanism is used between the proximity card and the reader/writer, that is, the reader/writer verifies the legitimacy of the card, and at the same time the card also verifies the legitimacy of the reader/writer. The card must conduct mutual authentication with the reader/writer three times before processing, and during the communication process All data in is encrypted. In addition, each area in the card has its own operating password and access conditions.
