RFID tags are small electronic devices that contain and can transmit information via radio waves. These tags consist of an antenna and a microchip that stores the information. They can be attached to objects, animals or even people to help track, identify and manage these items. RFID tags are used in various applications such as access control, logistics, inventory management and even healthcare.

How do RFID tags work?

RFID tags work by means of radio waves. When an RFID reader is placed close to an RFID tag, the reader emits a signal that activates the tag. The tag then sends information back to the reader via radio waves. The reader decodes this information and can use it for various purposes, such as identifying the object to which the tag is attached or checking a product's inventory levels. RFID tags can be passive or active. Passive tags do not have their own power source and are activated by the signal from the reader. Active tags have their own power source and can actively transmit signals, allowing them to be read at greater distances than passive tags.
