Final answer:
A tracking system allows staff to quickly notice a missing tool or item by using unique identifiers or barcodes and recording the item's location. It is commonly used in warehouses, retail stores, and libraries.
Step-by-step explanation:
A tracking system allows staff to quickly notice a missing tool or item. By using unique identifiers or barcodes, each tool or item can be tracked and its location recorded. When a tool or item is missing, staff can refer to the tracking system to identify its last known location.
This system is commonly used in warehouses, retail stores, and libraries. For example, in a library, each book can be tagged with a barcode. When a book is checked out, it is scanned and its barcode is recorded in the tracking system. If the book is not returned, library staff can easily identify it as a missing item and take appropriate action.
