RFID (Radio Frequency Identification) is a technology that uses radio waves to identify and track objects. RFID consists of two main components: a tag and a reader. A tag is a small device that contains a chip and an antenna that can store and transmit data. A reader is a device that can communicate with the tag and read or write data to it.

There are different types of RFID tags and readers, depending on their frequency, memory capacity, data protection, and compatibility. One of the most common types of RFID is 125khz RFID, which operates at a low frequency of 125 kilohertz. 125khz RFID tags and readers are widely used for various applications, such as access control, security, identification, etc.

125khz RFID reader writer use for read and write 125khz RFID card and tag .

Radio-frequency identification(RFID) is a technology that uses communication via radio waves to exchange data between a reader and an electronic tag attached to an object, for the purpose of identification and tracking. Now there is a growing number of applications in the area of security.

There are normally three ranges of RFID frequency: Low Frequency (LF), High Frequency (HF), and Ultra-high Frequency (UHF). The different class covers a different range of frequency, one most important of the frequency is that determines the reading distance of tags and this distance directly determine the application of the frequency to certain applications.

Most of RFID 125Khz RFID card or tag is read-only, can not write or program. Some customer use 125Khz RFID reader writer copier or cloner.
