Hi Sergio,
The Object you create in the first Microflow, that you used to fill an Attribute with the scanned value, you can pass on to the next Atrifact. If after the Microflow you open a Page, the Object to pass is the PageParameter. On that Page, you can use that Object as a Parameter in the Microflow that you trigger. Also, that PageParameter can be the source of your Data view so ahow the progress of scanning.
If you call a second Microflow from the first one the Parameter of the Microflow is used to pass the Object.
Go Make It
