T5577 card is also called radio frequency card, radio frequency card is intelligent IC card in a class of cards, is a new technology developed in the world in recent years, it successfully combined radio frequency identification technology and T5577 card technology, to end the passive (no power supply in the card) and no contact this problem, is a major breakthrough in the field of electronic devices.

T5577 RF card standard classification: active card and passive card, low frequency card, medium frequency RF card and high frequency RF card, active RF card and passive RF card, dense coupling card.


What is active card and passive card?


Active refers to the card inside the battery to provide power, its action distance is long, but the life is limited, larger, high cost, and not suitable for work in harsh environment; passive card without battery, it uses beam power technology to convert the received RF energy into DC power for the card circuit power, its action distance is relatively short active card, but the life is long and the working environment requirements are not high.


What is low frequency card?


Medium frequency RF card and high frequency RF card. Low frequency RF card mainly has two kinds of 125kHz and 134.2kHz, medium frequency RF card frequency mainly for 13.56MHz, high frequency RF card mainly for 433MHz, 915MHz, 2.45GHz, 5.8GHz, etc.. Low frequency system is mainly used for short distance, low cost applications active and passive?


What is active RF card and passive RF card?


Active RF card with its own RF energy actively send data to the reader; Passive RF card use modulated scattering way to transmit data, it must use the reader's carrier to modulate its own signal, this kind of technology is suitable for use in access control or traffic applications, because the reader can ensure that only activate the RF card within a certain range. In the case of the obstacle, with the modulation scattering method, the energy of the reader must come and go through the obstacle twice. And the active way the radio frequency card transmits the signal only passes through the obstacle once, therefore the active way works the radio frequency card mainly uses in the application which has the obstacle, the distance is farther (may reach 30 meters).


What is a close coupled card?


Close-coupled cards (acting distance less than 15 cm), sparsely coupled cards (acting distance about 1 m) and long-range cards (acting distance from 1 m to 10 m and even further).


The most important advantage of the radio frequency identification system is non-contact identification, it can penetrate snow, fog, ice, paint, dust and dirt and bar code can not use the harsh environment to read the tag, and read the speed is extremely fast, most cases less than 100 milliseconds. The speed-reading capability of active RFID systems is also an important benefit. It can be used for interactive operations such as process tracking and maintenance tracking.


At present the radio frequency card technology is mainly used in telecommunications, banking, securities, insurance, transportation, industry and commerce,, finance,, real estate, health, logistics, shopping malls and other social sectors preferred products.
