AssetScan

AssetScan allows you to display scannable barcodes or QR codes on your iOS/iPadOS device for any information you want.
Designed primarily to allow scanning of Serial Number, Asset Tag and Owner information. These can be set manually, however the true power is when managing many devices in an organisation with an MDM and using Apple's Apps & Books (formally VPP) where you can push down automatically an App Config detailing what you want to display.

Any MDM that supports Mobile App Config may be used, however AssetScan has been optimised for Jamf Pro and our help documentation is tailored for use with it.

WARNING! Only enrol your device in an MDM that you trust completely. An MDM can control or erase your device and potentially allow the owner to see your data.
