GS1 data integrity
Inspect GS1 codes for both symbol quality and correct data
GS1 compliance is more than obtaining a successful decode. Oxford Vision Systems checks the chosen GS1 data carrier, validates encoded Application Identifiers and compares critical fields with the product or production order.
Application focus
Match the code to the GS1 application
A configured inspection can parse fields such as GTIN, batch or lot, expiry date, serial number and SSCC. It checks mandatory data, field length and format, and can compare values with an approved record from the line controller, MES, ERP, label-management system or database.
Quality requirements depend on the symbol, use case and GS1 Symbol Specification Table. We review the scanning environment and acceptance criteria with your quality team rather than applying a generic pass threshold to every product.

Next generation barcodes
Read the 2D readiness guide Prepare for QR Codes with GS1 Digital Link
Understand the gradual 2027 retail transition and the inspection checks needed for co-located linear and 2D codes.
A proven project route
From sample to a production-ready inspection
We define the pass criteria first, prove the imaging and data logic, then integrate the complete inspection and reject sequence.
Application review
Product, code, substrate, speed, line layout and data requirements.
Sample trials
Optics, lighting, resolution and achievable tolerance tested on real packs.
System integration
Camera, controls, guarding, reject and upstream interfaces engineered together.
Commissioning
Recipes, fault handling, training and agreed acceptance tests completed.
Common questions
What manufacturers ask us
Every line is different. These are the practical questions that shape a dependable barcode verification project.
Ask an engineerDoes a readable barcode mean it is GS1 compliant?+
No. A symbol can decode while containing the wrong identifier, incorrect structure or unsuitable print quality for its intended GS1 application.
Can you validate Application Identifiers?+
Yes. Rules can check that required AIs are present and that their values meet the expected format, length and product data.
Can the system compare a GTIN with the selected SKU?+
Yes. Product and code data can be linked through a recipe, PLC, database or production-order interface.
