How to Read Multiple Barcodes with IronBarcode: Live Demo Recap

Regan Pun

March 27, 2025

In a recent live session, the Iron Software team demonstrated how to generate and read multiple barcode formats using IronBarcode. Led by Our Sales Engineer Shadman Majid with Craig Beaumont (Sales Lead), the session covered everything from simple barcode generation to advanced reading use cases, showing just how fast and flexible the IronBarcode library is for real-world applications.

Quick Recap of the Webinar: Barcode Generation

Shadman started by walking through how easy it is to generate barcodes with just a few lines of C# code using IronBarcode. The tool supports a wide range of barcode formats and makes it simple to customize output as PNG or PDF. This is ideal for industries needing fast and reliable barcode generation, from manufacturing to logistics.

Reading Multiple Barcode Formats with Craig

After the generation demo, Craig took over for the barcode reading capabilities of IronBarcode.

These features make IronBarcode ideal for complex automation workflows, especially where documents may contain more than one barcode type or when handling bulk data.

Common Use Cases Across Industries

Craig also shared practical use cases where IronBarcode is already making an impact:

Inventory & Asset Management – Track stock and locate products with real-time scanning.
Document Processing – Automate workflows by extracting barcode data from PDFs or scanned files.
Logistics & Supply Chain – Read shipping labels for order tracking and warehouse automation.
Healthcare – Scan patient wristbands, prescriptions, and medical records for accurate recordkeeping.
Payments & Ticketing – Validate QR codes for entry, discounts, and digital transactions.
Manufacturing – Track work orders and ensure quality control with barcode-enabled systems.
Point-of-Sale (POS) – Speed up checkout by instantly scanning product barcodes.
Security & ID Verification – Authenticate users with barcode-based ID and access credentials.

Live Demo: Reading Single and Multiple Barcodes

Shadman returned to demonstrate how IronBarcode handles both single and multiple barcode reads in real time.
