If you create your own barcode tags (labels) using 2D barcodes (e.g. QR, Data Matrix or PDF-417) and embed descriptive information in those barcodes, you can use the Response text for status updates.
Database Builder is ideal when you need to directly update your asset or ID validation database. The trade-off is that the app-user can only input text to a single form field.
Also, when using a standard Record Scans service type, you can prompt the app-user for multiple form entries, secondary scans, photos, signatures, GPS locations, etc with each scan. However, this Records Scans data does not update directly to your validation database. Instead, you need to export those scan records. Then, re-import to your database unless you use the Postback option (see below).
