The technology commonly used for automatic inventory tracking is known as barcode scanning and RFID (Radio Frequency Identification). These systems allow businesses to efficiently monitor stock levels and movements in real time. Barcode scanning uses printed labels that can be quickly identified by handheld devices, while RFID employs electromagnetic fields to automatically identify and track tags attached to items. Together, these technologies minimize human error, enhance inventory management, and significantly reduce the time needed for stocktaking processes.
