A/B Barcode Compare for Pick Lists, Packing Lists and More

The purpose of A/B Compare is to compare two barcode scans. For instance, if the second scan matches the first scan, the app will display the Valid response. On the other hand, ff they don’t match, the Invalid response will show up. For this option,  you will need an internet connectivity.

A/B Barcode Compare – Application example

First, the packer scans the barcode on a pick, pack, or delivery list. Secondly, the packer can scan the barcode on the target item to validate they match. If they match, the app user can be optionally prompted to scan each item to be part of that formal scan record.

You can use the built-in camera of iOS and Android devices or other scanning accessories to scan your barcodes. Importantly, while the camera is fast, scanning accessories have the benefit of a ‘pointer’ to target barcodes at a distance. Furthermore, if set up with a carriage return suffix (typically a default setting), then the scan will auto-advance after each scan.

Notably, in some use cases, the first and second barcode scanned may not be exactly alike. For example, they may have different suffixes or prefixes. If that’s the case, you can use our Alter Scan Value to normalize. If you have any questions on Alter Scan or any other aspect of  A/B compare, please email us at support@codereadr.com.

Batch Barcode Scanning – For tracking Inventory and Assets

First, you can complement A/B Barcode Compare with smart, fast, sequential barcode scanning. Please look at our Smart Batch Barcode Scanning article for more information.

If the barcodes you need to scan are very close together, you have several options, including:

  1. Select just the barcode type(s) you want to scan on the Advanced step when creating/editing your Service.
  2. Use our Pattern Validation feature to indicate the validity of the scan to your app users.
  3. Enable the Barcode Preview feature so your app users can pick the target barcode within the camera view.
  4. Enable the app user to resize the decoding area within the camera view.
  5. Use a scanning accessory to point the scanner at the target barcode (see video below).

This video displays Honeywell Captuvo barcode scanning sled with the ‘point and shoot’ targeting. Importantly, it does not use or show A/B Compare. Nevertheless, it will give you an idea of how you can target barcodes.
