So, we only have 1D asset tags, will that work with Manifest?

No. Manifest does not support 1D asset tags.  Because Manifest work instructions are often augmented with 3D content that needs to be spatially anchored to physical equipment, QR codes are required. 1D asset tags do not contain enough information.  However, data from 1D asset tags can be imported into Manifest as part of an Asset import process. The imported data can then be used to complete the Manifest Asset Tag ID which is how Manifest identifies Assets (equipment) in the system. The Manifest Asset Tag is a QR code that can also be used to spatially anchor 3D content associated with Manifest work instructions.
