Broadly speaking, an asset tag is any label used to identify one's property (or 'assets'). Most asset labels feature a unique serial number or barcode that can be used distinguish the labelled object from other, similar-looking items.
Asset tags are frequently used by businesses and other organisations as a loss prevention measure. High-value items such as computers, tools, and electrical appliances will each be assigned a unique serial number (or barcode) and marked accordingly using some sort of label or tag. Additionally, it is quite common for a business to print their name and/or logo on their asset labels for extra ease of identification.
