Scan Multiple Barcodes and QR Codes at Once
Multiple barcode scanning is time-efficient in various scenarios, such as shipping labels, supermarket price tags, inventory counting, etc. It greatly speeds up the barcode scanning process and streamlines the workflow.
Depending on different use cases, the count of barcodes in one image can vary from a few to dozens. And the barcodes can vary in symbologies (1D, QR code, MaxiCode, etc.) and sizes. As to the layout, the barcodes can be neatly placed in a matrix or randomly scattered.
ONLINE BARCODE AND QR CODE SCANNER
If You Are a Software Developer
In this article, we are going to examine how Dynamsoft’s barcode SDK performs in multiple barcode scanning situations.
Bulk Scan Barcodes and MaxiCode on Shipping Labels
Take a UPS shipping label for example, there are two linear barcodes and one MaxiCode printed. To make use of the contextual information, we can specify the barcode type as following:
Below is the Python code snippet to set barcode format and count to read:
settings = reader.get_runtime_settings()
settings.barcode_format_ids = EnumBarcodeFormat.BF_ALL | BF_MAXICODE
settings.excepted_barcodes_count = 32
reader.update_runtime_settings(settings)
Here is the returned result:
Cost 78 ms.
Found 3 barcode(s) in this file.
Scan Barcodes for Inventory Counting
Another example is multiple barcodes printed on the product packaging. This is often seen in inventory counting. This image contains 3 identical UPC-A codes and 3 identical Code 39 Extended. Here is the returned result:
Cost 281 ms.
Found 6 barcode(s) in this file.
To expedite the counting procedure, Dynamsoft Barcode Reader is optimized for scanning dozens of codes at once. For example, the following image contains 32 barcodes. Dynamsoft’s barcode scanner can scan them all successfully in 796ms.
The following is an example of 70 UPC-A codes in one image.
Codes of Various Barcode Formats in Random Placement
Dynamsoft’s barcode and QR code SDK is capable of recognizing barcodes in different angles and in different sizes. Its proprietary algorithm ensures that scanning multiple codes only takes a fraction longer compared with scanning a single barcode.
Need to Scan Dozens of Barcodes?
In some cases, you may need to scan dozens of barcodes in one batch. For example,
- Inventory managers take a picture of dozens of products and run stock counting and audit.
- Retail stores deploy aisle-scanning robots to monitor product availability and misplacements.
We have a high-end product - Dynamsoft Panorama - customized for demanding scenarios like these. Discuss with our friendly and helpful support staff today if you have interest.
