Asset tagging is the process of labeling or marking physical assets with a unique identifier, such as a barcode or RFID tag, to track and manage those assets. 

Asset tagging is commonly used in businesses and organizations to keep track of equipment, tools, and other physical assets. 

The unique identifier on the asset tag can be used to link the physical asset to a digital record in a database, allowing businesses to track the location, condition, and other important information about the asset. 

Asset tagging can help businesses to improve asset management, reduce loss and theft, and improve overall efficiency. Some common applications of asset tagging include tracking IT equipment, tools and machinery, vehicles, and office furniture.
