General Use Cases​

Example app

The following use cases have been compiled into a dedicated example app. If you want to see more than just code snippets, check out the example app on GitHub.

Scanning Single Barcodes​

The Scanbot Barcode Scanner SDK is quick and easy to integrate by design. Even in its default configuration, the Scanbot SDK scans barcodes rapidly and reliably in challenging conditions. Notably, all scanning operations are performed offline, on-device only, which ensures high speed and data privacy.

Yet, there are specific use cases where tweaking the configuration can significantly improve the user experience and scanning performance, such as when you want to enable the scanning of multiple codes at once or tiny or distant barcodes.

Scanning Multiple Barcodes​

If you need to scan multiple barcodes simultaneously, you can configure the SDK to detect and extract all barcodes visible in the live view. If desired, this functionality can be enriched with an AR Overlay, which lets you visually highlight the barcodes in view.

Batch Scanning​

Batch scanning, like multiple barcode scanning, allows users to scan multiple unique barcodes within a single session. A viewfinder added to the live view helps users target only the desired codes, improving their scan experience and control.

Scanning Tiny Barcodes​

Are you dealing with exceptionally small barcodes, like those typically found on electrical components? For this case, you can explicitly set a short focus distance for the camera. This adjustment allows the device to be moved very close to the small barcodes, improving image sharpness and scanning performance.

Scanning Distant Barcodes​

In scenarios where barcodes are positioned in hard-to-reach locations, you can drastically improve the scanning experience by leveraging the camera’s optical zoom functionality. The Scanbot SDK allows you to enable and control the optical and digital zoom. This ensures a suitable image crop of distant barcodes.

Detecting Barcodes on Still Images​

The Scanbot Barcode Scanner SDK offers advanced capabilities for reading barcodes from static images, such as photos or PDFs, imported from the gallery or the device’s storage.

AR Overlay Use Cases​

Displaying an extra layer of information in the live view is useful in a range of scanning use cases. With the Barcode AR Overlay, you can highlight barcodes to provide feedback on scanned barcodes or locate specific items. Alternatively, AR Overlay can display additional information based on the code’s content, like the amount in stock or product details.

Here is an overview of AR-enhanced use cases:

  • AR-MultiScan: Quickly scan multiple barcodes in one go, highlighting scanned codes.
  • AR-SelectScan: Selectively capture barcodes by tapping them.
  • AR-FindAndPick: Locate specific items with a pre-defined barcode value in a large inventory.
  • AR-ScanAndCount: Count items by scanning their barcodes.
  • AR-BarcodeVision: View additional information about scanned items, such as product or stock details, reviews, or video demos.
