RFIDtähiseid

RFIDtähiseid, commonly known as RFID tags, are small electronic devices that store and transmit data wirelessly. They are a key component of Radio-Frequency Identification (RFID) technology, which allows for the automatic identification and tracking of objects. An RFID tag typically consists of a microchip, an antenna, and a substrate. The microchip stores the data, while the antenna transmits and receives radio waves. The substrate holds these components together.

There are two main types of RFID tags: passive and active. Passive tags do not have their own power source and are powered by the radio waves emitted by an RFID reader. They are generally less expensive and have a shorter read range. Active tags, on the other hand, contain a battery, which allows them to transmit signals over longer distances and more frequently. This also makes them more expensive.

RFID tags operate by responding to signals from an RFID reader. When a reader's radio waves interact with an RFID tag's antenna, the tag is energized (if passive) or its existing power source is used (if active). The tag then transmits its stored data back to the reader. This data can include unique identification numbers, product information, or other relevant details.

The applications of RFIDtähiseid are widespread. They are used in inventory management, supply chain logistics, access control systems, payment systems (like contactless credit cards), animal tracking, and even for identifying and tracking library books. Their ability to be read without direct line-of-sight makes them highly versatile for automated data capture and management across various industries.
