How Dynamsoft's Bulk Barcode Scanner Achieves Near 100% Accuracy

Accurately scanning 20+ barcodes simultaneously can be challenging. Blurry images, skewed barcodes, and duplicates often result in scanning inaccuracies and costly operational delays. Dynamsoft’s Batch Barcode Scanner addresses these challenges head-on by leveraging advanced multi-frame imaging, intelligent data validation, and innovative AR-based duplication detection. In this post, we’ll explore how Dynamsoft’s cutting-edge batch barcode scanning technology achieves near 100% accuracy—transforming your bulk barcode scanning into a fast, reliable, and hassle-free process.

How Batch Barcode Scanner Achieves Near 100% Accuracy

  1. Stitch Close-up Frames into One Panoramic Image

    When multiple barcodes are captured in one frame, barcodes often become small, blurry, or skewed—particularly at the edges. To overcome this, the bulk barcode scanner captures multiple frames, each clearly focusing on just a portion of the barcode area from different angles and distances. These partial frames are seamlessly stitched together into a panoramic view, ensuring every barcode – whether it’s a linear barcode, QR code, Data Matrix or any other 2D barcode – is sharp, properly sized, and accurately decoded.

  2. Overlapping & Cross-validation

    The bulk barcode scanner uses overlapping image-capture techniques, scanning each barcode multiple times. Barcode results from different frames are cross-validated, significantly increasing result confidence. Barcodes that fail the cross-verification step are marked as questionable for further review.

  3. Real-Time Interaction via On-screen Overlay

    The bulk barcode scanner continuously displays real-time scanning results as visual overlays directly on the device’s screen. Immediate feedback enables users to intuitively adjust the device’s angle, distance, or lighting conditions on the spot, facilitating optimal barcode scanning and improved accuracy.

  4. Pattern Inference & Export into CSV

    When barcodes are arranged in structured layouts—such as grids or lines—the bulk barcode scanner uses pattern-inference algorithms to intelligently anticipate barcode positions. This works whether it’s a neatly aligned grid or a row-by-row layout with uneven spacing.

  5. Flexible Camera Mode for Your Needs (iOS Only)

    Our Batch Barcode Scanner supports both the AR Camera and the native camera, giving users the flexibility to choose the best tool for the task.

    Flexible Camera Mode for Your Needs

    AR Camera – Best for Duplicate Detection

    Powered by iOS augmented reality (AR) technology, the AR Camera brings spatial awareness to barcode scanning. It tracks the physical location of each barcode, allowing the system to associate each code with a specific item. This mode is ideal for scenarios where many of the barcodes are duplicates—such as when counting multiple units of the same item.

    Native Camera – Best for Camera Control

    The native camera mode offers greater control over camera settings, including zoom, camera selection (front or rear), and support for ultra-close scanning. This mode is perfect when precise camera handling is needed.

  6. Manual Review and Editing Before Export

    Before exporting the final results, users have the option to manually add, delete, or update any barcode on the generated panoramic image.

Dynamsoft Barcode Reader vs. Batch Barcode Scanner: Which Should You Choose?

Dynamsoft’s Batch Barcode Scanner is powered by its core Dynamsoft Barcode Reader SDK. While the SDK efficiently handles multiple barcode scans, the Batch Barcode Scanner elevates performance to the next level. Here’s a comparison:

Feature Dynamsoft Barcode Reader Batch Barcode Scanner
Barcode Reading Method Reads from single camera frames without overlapping or stitching. Results can be exported as a plain text list. Reads from multiple frames and stitches them into a single panoramic image.
Reading Rate Dependent on image clarity. May not consistently achieve high accuracy. Consistently achieves a near 100% reading rate through combining frames and advanced processing.
Number of Barcodes Supported Limited; Capable of reading multiple barcodes, however, recommended for scenarios with fewer than 10 barcodes per frame. Suitable for light to moderate multi-barcode tasks Unlimited; effectively handles many barcodes using overlapping and panorama technologies. Suitable for high-volume barcode scanning
Augmented Reality (AR) Support No AR support. AR support available (iOS only).
Handling Duplicate Barcode Values Struggles to distinguish Accurately identifies duplicates with ARCamera
Supported Platforms Web Browser, iOS, Android, Windows, Linux, macOS iOS, Windows, Linux (Android or Web support is yet to come).
Ideal Usage Scenario Small-scale applications with fewer barcodes per image, suitable for simpler barcode reading tasks. Large-scale or complex barcode applications, ideal for scenarios requiring higher reliability and accuracy
