RFID Transponders, Tags

Radio Frequency Identification (RFID) transponders, tags and systems are electronic devices used to track and identify objects. A typical RFID device, known as a transponder, typically consists of an integrated circuit or microchip, an antenna, and a reader. The microchip stores a unique identifier, or code, which is used to identify the device to its user. The antenna enables the device to communicate with a reader device, which is placed near the object, usually a few meters away. When the device is in range of the reader, the reader "listens" for the code and then returns the code to the user.

RFID transponders and tags are used in many different applications, ranging from inventory control to asset tracking. In the case of inventory control, RFID tags can be used to track inventory levels, product availability, and product shelf life. RFID tags can also be used to identify, or "tag," different parts of a product, allowing for more efficient tracking of different aspects of production and delivery. It can also be used in asset tracking - RFID tags can be used to track the location of large objects such as furniture, appliances, or other equipment.

The working principle of RFID transponders and tags is relatively straightforward. The tag is placed near a reader device and the reader accesses the tag\'s stored code. The code is sent back to the reader device, allowing the user to identify the object tagged. The tag itself does not contain any information, so the reader must be configured to interpret the code it receives from the tag. In some cases, the reader may even be connected to a computer, allowing the user to access a database of information related to the tag\'s code.

RFID transponders, tags and systems have been around for many years, but their popularity and usefulness continues to grow. With their proven track record and widespread availability, RFID tags are becoming increasingly prevalent in many industries, ranging from retail to healthcare. The simple working principle of RFID tags, coupled with their practical applications, makes them a valuable tool for many industries today.
