Barcode Verification
Harford’s Barcode Verification solution automatically verifies 1D, 2D and QR codes during production, ensuring the barcodes are readable and matched to the correct product, packaging or component.
Improve accuracy, traceability and compliance while reducing errors, waste and recall risk.
Automated Barcode Verification for Production Lines
Harford’s barcode verification system automatically checks 1D, 2D and QR codes at key points throughout the production line, ensuring the correct codes are matched to the right products, packaging and components.
Barcode verification can be carried out across different production zones, helping manufacturers identify incorrect or unreadable codes before products progress further. Automated checks reduce reliance on manual inspection, minimising human error, rework and waste while maintaining accuracy at production line speeds.
Prevent Barcode Errors Before Products Reach Customers
Even a small barcode error can lead to incorrect products, compliance issues or costly recalls. Harford’s Barcode Verification solution automatically checks that barcodes are correct and readable, and that the right components are matched to the right products.
Incorrect, unreadable or mismatched codes can be automatically flagged and rejected, preventing non conforming products from progressing further. This helps manufacturers reduce risk, improve efficiency and maintain accurate, compliant production.
Ensure Barcode Readability, Data Matching and Compliance
Harford Barcode Verification solutions protect your business against costly supermarket rejections by verifying whether the barcode itself is good enough to read while validating the barcode against the products on your line. Operating as an integral component of our wider inline inspection suite, the system uses inline scanners and vision technology to perform standard verification, grading print quality from A to F, alongside full inspection to match complex 1D and 2D codes (such as ERP codes and version numbers) directly to product specifications with 99.9% accuracy. Fully aligned with strict supermarket codes of practice, Harford provides real-time visibility, performance reporting, and automated line-stop capability to halt production the moment a bad or mismatched barcode is detected.
Multi-Point Barcode Inspection & Verification
Harford’s Barcode Verification solution combines real-time inspection and quality verification at every stage of your production line to ensure 100% packaging accuracy and strict GS1 compliance. Positioned right from the start of the line, multi-point scanner networks independently validate both standard 1D barcodes for end customers and advanced 2D internal codes for supplier traceability, checking critical data such as ERP codes, artwork versions, material codes, product descriptions, etc.
From individual products to final cases, the system continuously monitors code position, type, and print quality in real time; if any detail fails to align, it immediately alerts the operator, rejects the faulty item to a bin, or halts the line to prevent non-compliant product from leaving your facility.
1D, 2D, EAN & QR Code Verification
Harford supports verification of multiple barcode formats, including 1D barcodes such as EAN 8 and EAN 13, and 2D barcodes including Data Matrix and QR codes.
While traditional 1D barcodes contain a relatively limited amount of data, 2D codes such as Data Matrix can store significantly more information within a smaller area. This makes them suitable for applications requiring greater product, component or traceability data. For reliable verification at production line speeds, barcode size, quality and the amount of encoded information should be considered.
Real-Time Reject Tracking & Customisable Line Control
Harford’s system captures every good read, bad read, or no-read in real time, delivering total visibility across your entire production run. Some factories would deliberately trigger consecutive “no reads” to force an automated line stop for mandatory operator inspection. Harford’s system offers fully flexible control parameters tailored to your factory’s specific needs, allowing you to easily customise thresholds like the standard 3-no-read limit or other limits enforced by major supermarkets.
By logging image captures, operator comments, and exact failure types, the system delivers complete product ID traceability for every reject, giving you the precise data needed to pinpoint quality issues, understand failure reasons, and satisfy strict retailer standards.
Barcode Verification for Manufacturing Compliance
Accurate barcode verification is particularly important in industries where product identification, traceability and compliance are critical. Harford supports manufacturers across Food & Beverage, Pharmaceutical, Health & Beauty, Chemical and FMCG industries, helping ensure the correct barcodes, packaging and components are used throughout production.
Automated verification helps manufacturers reduce barcode related errors, support supply chain integrity and minimise the risk of non compliant products reaching customers.
High Information Density 2D or QR Codes
Store more information within a small area, including packaging component and version control data.
Digital Information Encoding
Encode more complex product and traceability information than conventional 1D barcodes.
Omni Directional Reading
Read codes in different orientations, supporting reliable barcode scanning at production line speeds.
Integrated Error Correction
Maintain readability even when part of a barcode is damaged or obscured, depending on the extent of the damage.
Scalable & Printable
Print and read codes at different sizes and levels of magnification, subject to resolution and production line speed.
