The technology that utilizes electromagnetic fields to identify and track tags attached to objects is known as Radio Frequency Identification (RFID). RFID systems consist of tags, readers, and a database. The tags, attached to items, emit signals that are captured by the readers. This technology is widely used in various sectors such as retail, logistics, and healthcare for inventory management, asset tracking, and ensuring product authenticity. RFID improves operational efficiency by providing real-time data and reducing human error.
