RFID stands for Radio Frequency Identification. It is a wireless communication technology that uses radio waves to identify and track tags attached to objects.
An RFID system consists of three main components: a reader, an antenna, and RFID tags. The reader emits radio signals that activate the tag, which then responds by transmitting its data back to the reader. This allows the tag’s identity and other information to be read wirelessly.
RFID technology is widely used in applications such as supply chain management, asset tracking, electronic payment systems, access control, vehicle identification, and many other areas where wireless data transfer is useful.
RFID是無線射頻識別(Radio Frequency Identification)技術的簡稱。這是一種無線通訊技術,可以透過無線電波來識別標籤或物品上的資訊。
RFID是一種自動識別和數據獲取技術,主要由三部分組成:讀寫器、天線和電子標籤。讀寫器發出無線電波,與電子標籤進行無線通訊,從而識別該標籤並讀取或寫入標籤內的數據。
RFID技術廣泛應用於物流管理、資產跟蹤、電子支付、門禁控制、車輛識別等領域,為無線數據傳輸提供了便利。
