Analysis of the characteristics of RFID low-frequency, high-frequency and ultra-high-frequency cards

Feb. 26, 2024

With the popularization and application of rfid technology, plays an important role in various application areas, widely used in intelligent library management, logistics management, security, animal husbandry, warehousing and logistics, electronic ticketing management, etc., these applications are closely related to our lives, bring great convenience to our work and life, rfid card has different frequency bands, high frequency, low frequency, UHF the three kinds of labels, different Frequency band rfid card and its applications and features are not the same, today with the rfid card manufacturers in Guangzhou, Jiezhong Intelligent Technology to understand:



Typical operating frequencies of low frequency RFID cards are 125 kHz and 134.2 kHz. the main features of this type of RFID card are its smaller data storage capacity, slower reading speed, and usually does not support the write function. the RFID card can be used in a wide range of applications, such as mobile phones, mobile phones, and other devices. The communication distance is limited to 10 centimeters, although it can be extended to 80 centimeters by adding devices such as power amplifiers. Low-frequency RFID cards are low cost and highly resistant to interference.

They are mainly used in communities for ID cards and access cards.



High-frequency RFID card operating frequency of 13.56MHZ, high-frequency card protocol, commonly used system ISO communication protocols are: ISO7816, 14443A, 14443B, 15693, etc., the application of this type of smart card has been very mature, it also has a faster data read/write speed for the 0-10 centimeter requirements close to the communication occasions is very suitable, like the city's bus card, Access cards, NFC business cards and other products are working in this band. With the progress of science and technology, in recent years, with anti-copying and anti-cracking security performance of high-frequency CPU chip RFID card has gradually replaced the M1 chip to become the new favorite high-frequency card, has gained more and more applications.

RFID UHF card generally refers to the card working in the 860 ~ 960M frequency band, the protocol is mainly 18000-6B and 18000-6C, this kind of intelligent UFH card usually has the characteristics of fast reading speed, long distance, conflict-resistant ability, etc. It is widely used in the field of logistics pallet card, turnover box card, warehouse management, etc. The UHF card's unique function of remote reading and group reading makes it easier to adapt to the UHF cards have unique remote reading and group reading functions, making it easier to adapt to complex environments.

Overall, choosing the right RFID card depends on application scenarios and needs. Low-frequency cards have advantages in complex environments, high-frequency cards are suitable for scenarios that require stable transmission, and uhf cards are suitable for applications that require extensive, high-speed identification.
