Which frequency RFID tag should be selected for different application scenarios?What are the differences between different frequency bands of RFID electronic tags?Can you distinguish between RFID low frequency, high frequency, and ultra-high frequency electronic tags in different scenarios? Below, with smart card and RFID tag manufacturer RZX Technology to understand the characteristics of RFID electronic tags, to help you quickly select in practical applications.

RFID radio frequency technology is a technology that stores data on an electronic data carrier and communicates wirelessly through a magnetic field or electromagnetic field to achieve the purpose of data exchange.Because RFID electronic tags have the characteristics of anti-harsh environment, high accuracy, flexibility and scalability, and anti-counterfeiting, they can be widely used in major neighborhoods, especially in logistics, express delivery, warehousing and other industries.

Low frequency RFID electronic tags are currently widely used in the field of animal individual tracking and identification at home and abroad, mainly using low frequency identification (frequency below 135KHz) chips, implanted into the animal body, technically very mature, domestic manufacturers have been able to master the corresponding technology.RFID animal tags effectively manage the whole process of animal growth.It can track and trace the breeding stock, epidemic prevention and control, meat quarantine and other situations, timely detect diseases and epidemics and solve them, reduce losses, and improve economic and social benefits.

The frequency bands used by high-frequency electronic tags are: 1MHz~400MHz, the main common specification is 13.56MHz the ISM band, the reading distance of the high-frequency label is about 3-10cm, compared with the low-frequency label, the transmission speed is faster, and the system technology is relatively mature, and the price of the terminal equipment to read is low, which is more common in RFID applications.

High-frequency RFID electronic tags are the mainstream labels of domestic RFID technology products, we are familiar with ISO14443A, ISO15693, etc., which are widely used in all walks of life consumer payment, anti-counterfeiting traceability, unmanned retail, self-service management, etc. Common are high-frequency book labels, NFC labels, consumer electronic labels, high-frequency anti-counterfeiting labels and so on.

Uhf electronic labels use the following frequency bands: 400MHz to 1GHz.Common specifications include 433MHz and 868mhz to 950MHz. The label reading distance is about 1-10m, the transmission rate is fast, the reading distance is long, the information transmission rate is fast, and a large number of labels can be read and identified at the same time, so it is especially suitable for logistics and supply chain management and other fields.Uhf tags have strong confidentiality, are not easy to be cracked, and have a wide range of effects. Today's advanced Internet of Things technology uses UHF electronic tag technology.

The UHF RFID electronic tag protocol is mainly 18000-6B and 18000-6C, which is widely used in logistics, vehicle management, jewelry management, file management, washing management, medical management and other fields. The unique remote reading and multi-label group reading function of UHF tags make it easier to adapt to complex environments.

Of course, different application scenarios in addition to taking into account the frequency of RFID electronic tags, reading distance, storage capacity and the price of supporting equipment, etc., the size of the tag and whether the external environment such as metal resistance and pressure resistance are also very important, only by understanding the situation that may occur in practical applications, can we quickly choose a suitable and practical electronic tag.
