Our A/B Compare feature allows your app users to match two or three barcode or text values. First, the user scans the barcode on a list or asset. Secondly, the user scans the barcode on the target asset(s) to validate the match. If they all match, the app user will see a green valid screen. If they do not match, the app user will see a red invalid screen. If valid, the app user can optionally be prompted to collect associated data to be included in that formal scan record.
A primary scan refers to the scan initiated from the app’s Tap to Scan screen. A question-answer scan refers to a scan made when the app user is prompted to do so after the primary scan. You can collect data with questions through barcode scanning. A question prompt can be a standard question asked after every scan or a session question. Learn how to create a session question here so app users can answer your prompts. A database refers to the database associated with a Validate Scans service type. It includes the barcode value and the intended response after each scan. Learn more about creating and filling a barcode database here.
This technology works when using the built-in camera of iOS and Android OS devices. It also works with dedicated scanners, like those offered by Honeywell and Zebra. When using a dedicated scanner in the keyboard emulation mode with a CR/LF suffix, the app user doesn’t have to tap the screen to sequentially scan or to submit the record. That makes repetitive scanning faster.
