Preview Multiple Barcodes Simultaneously

Assets with multiple barcodes positioned closely together can be challenging to scan.

Standard options

a) If the target barcode is a different type than the surrounding barcodes, then you can select only that format (or formats) to read. You enable this on the Advanced step when creating/editing a service. Also, you can configure this from the app’s settings.

b) With our standard scan engine (not SD PRO yet), the app user can change the decoding window’s size and shape within the camera view.

c) You can use a barcode scanning accessory with a pointing light that you can position over the target barcode before pulling the scan trigger.

d) Also, you can create a ‘Validate Scans’ service. Here, if you select Pattern Validation, the app users will see a red Invalid screen when they scan wrong barcodes. For example, you could make only a certain number of digits be valid and discard the Invalid scans.

Barcode Preview (AR)

A great alternative to the standard options is our Barcode Preview technology. Within the camera view of our SD PRO scan engine upgrade, app users can preview the values of multiple barcodes simultaneously. Then, they can select the correct barcode to capture and submit to a scan record. Users can use this feature with the standard options to make it even more precise.


To try it, first, sign in to the codeREADr app with SD PRO enabled. Secondly, in the app’s settings select ‘Barcode Preview (AR)’. Thirdly, position the camera over multiple barcodes within the camera view. Then, tap the individual barcode that you want to capture. [If you don’t have SD PRO enabled, follow the link in ‘b’ above to get testing access.]

As the camera and auto-focus technology used on smartphones and tablets continue to advance along with codeREADr’s scanning and decoding technology, we see a future where this preview process, augmented with auto-selection technology, could significantly improve the accuracy and efficiency of asset tracking applications.
