With the popularity and application of rfid electronic tags, rfid system in various fields of application plays an important role, which is widely used in intelligent library management, logistics management, security, animal husbandry, warehousing and logistics, electronic ticket management, etc., these applications are closely related to our lives, to our work and life has brought great convenience, rfid tags have different frequency bands, high frequency, Low-frequency, ultra-high-frequency tags of these three, different bands of rfid tags and their applications and characteristics are different, today with the RFID RFID card manufacturers in Guangzhou, Jiezhong Intelligent Technology to understand:
RFID low-frequency radio frequency card
Low-frequency RFID card typical operating frequency of 125 kHz and 134.2 kHz. the main feature of this type of RFID card is its smaller data storage capacity, slower reading speed, usually does not support the write function. The communication distance is limited to 10 centimeters, although it can be expanded to 80 centimeters by adding devices such as power amplifiers. However, they are gradually being phased out in applications such as ID keyfobs and access cards in neighborhoods due to the greater security concerns, such as ease of duplication and cloning. However, the low-frequency RFID card has low cost and strong anti-jamming ability, so it still has some application value in specific areas such as animal tracking.
RFID high-frequency radio frequency card
High-frequency radio frequency card operating frequency is 13.56MHZ, high-frequency card protocols, common system ISO communication protocols are: ISO7816, 14443A, 14443B, 15693, etc., the application of this class of smart cards has been very mature, it also has a faster data read out and write speeds, 0-10 centimeters for the requirements of the proximity of the communication occasions is very suitable, like the second generation ID card, the city, the city, the city of the card. Like everyone's second-generation ID card, the city's bus card, campus card, book tags, NFC tags, consumer electronic tags and other products are working in this band. With the progress of science and technology, in recent years, anti-replication 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.
UHF radio frequency card generally refers to the work in the 860 ~ 960M band electronic tags, protocols mainly 18000-6B and 18000-6C, this class of smart cards and electronic tags are typically characterized by fast read out speed, distance, anti-conflict ability, is widely used in logistics pallet card, turnover box card, warehousing inventory card, RFID vehicle management, jewelry management, file management, laundry Management and other fields, UHF radio frequency card unique long-distance reading and multi-tag group reading function, so that it is easier to adapt to complex environments, can be packaged according to the actual application of cards, printed tags, special tags and other complex forms.
Overall, the selection of the appropriate RF card depends on the application scenario and needs. Low-frequency cards have advantages in complex environments, high-frequency cards are suitable for scenarios that require stable transmission, and ultra-high-frequency cards are suitable for applications that require wide-ranging, high-speed identification.
