ID wristband built-in chip is attached to the trackable item of the product electronic code (EPC) physical carrier can be transmitted and identified, read and written globally. RFID as the construction (radio frequency identification) technology "Internet of things" in recent years, the key technology has attracted attention.
RFID is widely introduced to use
Radio frequency identification (RFID) it is a wireless communication technology, without mechanical or optical contact between the identification system and a specific target, can identify a specific target, and read and write the relevant data through radio signals. ID wristband RFID technology is based on a transformer coupling model in the low frequency range (energy transfer and signal transmission between the primary and secondary) and a spatial coupling model for radar detection of targets in the high frequency range. The radar emits electromagnetic signals and then transmits the target information back to the radar after hitting the target. (Receiver).
The radio signals are transmitted through the RF electromagnetic field and tags attached to the items to automatically identify and track the items. During the identification process, some tags receive energy from the electromagnetic field emitted by the identifier and do not require batteries. Alternatively, the tags themselves have a power source and can actively emit radio waves (electromagnetic fields tuned to radio frequencies). The tag contains electronically stored information that can be identified within meters. Unlike bar codes, the ID wristband built-in chip does not need to be located within sight of the identifier, but can also be embedded in the tracking object.
By communicating wirelessly with the RFID tag through an antenna, the RFID tag reader can read or write the tag identification code and store the data. ID wristband RFID technology can simultaneously identify high-speed moving objects and multiple tags. Operation is fast and easy.
