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.

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.

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.

AR - MultiScan

The MultiScan functionality allows users to hover over multiple barcodes in live view. As each barcode comes into view, it is instantly detected, highlighted with a floating AR overlay, and scanned. This feature is especially useful in scenarios where users must quickly scan multiple barcodes without manually selecting each one.

For example, in a warehouse setting where an employee needs to scan a variety of items in quick succession, MultiScan can speed up the process. The worker simply points their device at the products, and each barcode is automatically detected and scanned, with the AR overlay providing visual feedback and confirming successful scans.

AR - SelectScan

The SelectScan feature allows the user to hover over multiple barcodes in live view, detecting and marking each with an AR overlay. However, instead of automatically scanning every barcode, users must tap the marked barcodes to scan them selectively. Scanned barcodes are highlighted (i.e., with a contour box in a different color) and marked as scanned. SelectScan is handy when you want to enable users to pick specific barcodes from a group of items.

For example, consider a delivery driver with multiple packages on his truck but needs to scan and deliver only one or a few specific packages to a customer. All barcodes on the packages are detected and marked when they come into the live view, but only the manually selected ones are actually scanned.
