At present, more cards are used in society: magnetic cards, barcode cards, photoelectric cards, IC cards, etc. In recent years, non-contact ID proximity cards, non-contact IC proximity cards, and smart CPU cards have been introduced from abroad.
From the use point of view, magnetic cards, barcode cards, and photoelectric cards have been eliminated one after another. For example, magnetic cards on the surface of the market have been used most frequently. Magnetic strips on the surface are stored under the conditions of magnetic fields, static electricity, twists, and scratches. The information inside is easy to lose, and it is contact-type working principle. The card is easy to be dirty and needs to be cleaned or replaced frequently.
As one of the products of this series, the IC card has better confidentiality, capacity, and versatility than its predecessors. Traditional IC cards, after years of evolution and improvement, have formed uniform standards and are affordable. Has been widely used, but its contact-type working principle, there are many problems in the use of the process, such as the card's life is generally required to be replaced after 1 year; poor security, IC card anti-pollution is poor, can not have oil, give The reliability of use brings real problems.
In recent years, with the development of science and technology, the market for cards has become larger and larger, and the range of use has become wider and wider. Some international high-tech buildings have also introduced non-contact proximity cards. The appearance of the proximity card has made people have a new understanding of the application of the card. In the past, magnetic cards, barcode cards, and IC cards were limited to some security requirements, as well as some fee management aspects, while the proximity cards used their powerful advantages. To make up for the shortcomings of magnetic cards, barcode cards, and IC cards in the past.
The proximity card is a RF (RADIOFRDQUENGY) sensor identification technology used in the early industry. After being developed and improved by the developed countries in the United States and Europe in the past decade, it successfully combines the radio frequency technology with the IC card technology and solves the problem of passive ( The lack of power in the card and the absence of contact are major breakthroughs in the field of electronic devices.
The sensor card consists of an IC chip and an induction antenna and is completely sealed in a standard PVC card with no exposed parts. The work is usually done by radio waves between the proximity card and the reader. According to its chip, the proximity card can be simply divided into a read-write card and a read-only card, namely a sensing IC card and a sensing ID card. The card and equipment of the induction ID card system are relatively cheap, and the advanced management software also operates offline, so it is also an excellent choice.
Comprehensive application of the above products, magnetic cards, barcode cards, embossed cards, there is a low degree of security, short life, easy to wear, easy imitation; IC card is contact type, poor anti-pollution, wear, so the commonly used is the induction ID card system.
