How 58kHz insertable label works

58kHz insertable label usually refers to a radio frequency identification tag that uses a 58kHz high frequency signal. 58kHz is a common low-frequency RFID frequency, which is widely used in animal identification, access control systems, asset tracking and other scenarios.

Working principle

Radio frequency identification technology:

58kHz insertable label is a type of low-frequency RFID technology, usually composed of a tag and a reader. The RFID tag has a small chip and antenna built in, and the chip stores unique identification information.

Tag working:

58kHz RFID tag is a passive tag, which means it does not require its own power supply to work. Its working principle depends on the exchange of radio signals with the RFID reader.

When the tag is close to a reader with a 58kHz frequency, the reader emits a strong 58kHz electromagnetic signal. This signal is transmitted to the circuit inside the tag through the tag's antenna to power the tag.

Information exchange:

After receiving the electromagnetic signal, the tag activates its internal circuit and returns the unique ID number or other data stored in the tag. This return signal is a reverse radio signal, which is transmitted back to the reader by the tag's antenna.

After receiving this signal, the reader will decode and process it to obtain the tag's identification information and perform subsequent processing, such as verifying identity, recording information or triggering certain operations.

Operating frequency:

58kHz is a low-frequency (LF) RFID technology operating frequency with good penetration and long identification distance, and can usually identify thicker objects or materials. However, the storage capacity and data transmission speed of low-frequency RFID tags are usually not as good as high-frequency or ultra-high-frequency RFID tags.

In 58kHz RFID systems, the read and write distance is usually a few centimeters to a few meters, depending on the quality of the tag, the power of the reader and environmental factors.

Main applications:

Animal management: used for the identification of animals such as livestock and pets, which is convenient for tracking and management.

Access control system: In low-frequency RFID technology, 58kHz tags are used as access control cards, which can enter specific areas.

Asset management: It can be used for asset tags to track items, equipment, etc.

Book management: It is sometimes also used in the library's book management system to identify each book through tags.

Summary: 58kHz insertable labels are low-frequency RFID tags that work under the stimulation of electromagnetic waves from the reader through radio frequency identification technology. They do not require batteries, but are powered by electromagnetic signals received from the reader, which in turn return the stored information. They have a wide range of applications, especially in areas such as animal identification, access control and asset tracking.
