Smart tags are small, electronic labels that use technology to provide information about an object or item. They can be attached to products, documents, or even people, allowing for easy tracking and identification. Smart tags often use technologies like RFID (Radio Frequency Identification) or NFC (Near Field Communication) to communicate with devices, making it simple to access data with a smartphone or scanner. These tags can enhance inventory management, improve supply chain efficiency, and streamline processes in various industries. For example, in retail, smart tags help track merchandise, while in healthcare, they can monitor patient information and equipment.
