RFIDmerkkejä

RFIDmerkkejä, also known as RFID tags, are small devices that use radio waves to identify and track objects. They consist of a microchip that stores data and an antenna that transmits and receives radio signals. RFID tags come in various forms, including passive tags that draw power from the reader's radio waves and active tags that have their own power source.

The technology works by emitting radio waves from an RFID reader, which powers the tag and triggers it to send back its stored information. This information can include a unique identifier, product details, or other relevant data. The range of RFID communication varies depending on the type of tag and reader, from a few centimeters to several meters.

RFID technology has numerous applications across different industries. In retail, it is used for inventory management, tracking goods from the warehouse to the point of sale, and preventing theft. Logistics and supply chain management benefit from RFID for efficient tracking of shipments and ensuring accurate delivery. Animal tracking and identification utilize RFID tags to monitor livestock and pets. Access control systems commonly employ RFID cards for secure entry. Furthermore, RFID is used in contactless payment systems, library book tracking, and even in manufacturing for quality control and process monitoring. The ability of RFID to uniquely identify and track items without direct line-of-sight makes it a versatile and valuable technology.
