RFIDmerkkinä

RFIDmerkkinä is a Finnish term that translates to "RFID tag" or "RFID marker" in English. It refers to a small, electronic device that uses radio waves to identify and track objects. These tags consist of a microchip, an antenna, and a substrate. The microchip stores information about the item it is attached to, while the antenna transmits and receives radio signals.

RFIDmerkkinä 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, allowing for a longer read range. They are commonly used in applications such as inventory management, access control, supply chain logistics, and animal tracking.

The primary function of an RFIDmerkkinä is to enable contactless identification and data transfer. When an RFID reader emits radio waves, the tag's antenna captures these waves, powers the microchip, and transmits the stored data back to the reader. This allows for quick scanning and efficient data collection without the need for direct line of sight, unlike traditional barcodes. The information stored can range from simple product identification numbers to more complex data sets.
