What is
RFID technology
RFID is
wireless radio frequency identification technology, a non-contact automatic
identification technique that can automatically recognize targets and complete
data exchange without physical contact.
core
principle
It
relies on radio frequency signals to transmit energy via spatial
electromagnetic coupling, enabling the electronic tag attached to the object to
retrieve power and transmit stored unique identification data back to the
reader, thereby achieving target recognition without any manual intervention.
System
Composition
A
complete RFID system consists of three parts: the electronic tag (which stores
item information and is categorized into passive and active types), the reader
(which emits signals and decodes data), and the data processing system.
typical
characteristics
It
features the advantages of batch multi-label simultaneous reading, strong
penetration, resistance to oil stains and dust in harsh environments, and data
encryption/modification capabilities, with an identification range spanning
from a few centimeters to several tens of meters.
