The ServiceNow Agent mobile app allows the user to conduct asset audits by scanning asset barcodes or QR codes1.
The user can perform audits offline when they are in areas without connectivity1.
The app automatically compares the scanned assets against the expected assets based on the inventory records to identify discrepancies1.
The user can also view the audit results and generate reports from the app2. References:

According to the ServiceNow Hardware Asset Management documentation, the Retired state indicates that the asset is no longer in use and is ready for disposal or reuse. The substates of the Retired state are:
* Disposed: The asset has been discarded or recycled.
* Donated: The asset has been given away to a charity or a non-profit organization.
* Vendor Credit: The asset has been returned to the vendor for a credit or a refund.
* Sold: The asset has been sold to a third party.
The substate Pending Disposal is not valid for the Retired state, as it is only available for the states In Stock and In Transit. The substate Destroyed is not valid for the Retired state, as it is only available for the state In Use. References:

* Hardware model normalization is a feature that enables users to normalize the details, such as manufacturer, product, model, and device type, of hardware and consumable models1
* Hardware model normalization uses the data from the models and compares it against the data in the Hardware Model Normalization Content Service, which is a cloud-based service that provides standardized and enriched information about hardware models1
* Hardware model normalization sets the normalized display name for each model record based on three attributes: Name, Manufacturer, and Model number2
* The normalized display name is a combination of these three attributes, separated by a hyphen, for example: Dell-Inc.-OptiPlex 70102
* The normalized display name helps to identify and group models with similar properties and reduce duplicates and inconsistencies in the model catalog and the Configuration Management Database (CMDB)2 s: 1: Hardware Model Normalization - ServiceNow 2: Set the normalized display name - ServiceNow
