Which technology is associated with tracking items in real time?

The correct answer, RFID (Radio Frequency Identification), is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. These tags contain electronically stored information and can be read by RFID readers without line-of-sight, allowing for real-time tracking of items throughout a supply chain. This capability enhances inventory management, reduces errors, and speeds up processes compared to other methods.

Unlike barcode scanning, which requires a direct line of sight and manual scanning, RFID can capture data from multiple items simultaneously and does not require a physical scan, making it ideal for real-time applications. EDI (Electronic Data Interchange) is more focused on the electronic transfer of data between systems rather than item tracking itself. Manual inventory checks rely on human intervention and are typically less efficient and responsive compared to automated systems like RFID. Therefore, the real-time tracking capabilities of RFID make it a superior choice for modern asset management.
