Barcode Verification Capabilities

Label Anti-Mixup Validation

Compares decoded barcode or DataMatrix content against master job values, SQL whitelists, or approved Excel imports.

Multiple 1D & 2D Symbologies

Supports DataMatrix and GS1 DataMatrix, QR Code, Code 128, EAN, Code 39, Code 93, Aztec, Codabar, PDF417, Pharmacode, and other configured formats.

Rotation & Inverted Code Options

Selected decoder backends can search rotated symbols and light-on-dark codes when these options are enabled in the inspection recipe.

Combined Barcode & Printed Text Matching

Simultaneously scans 2D DataMatrix and verifies adjacent printed human-readable text strings.

Single-Use & Usage-Limited Control

Tracks single-use serial numbers to block duplicate labels and trigger instant line rejection.

PLC Rejection & Line Interlocking

Sends pass/fail output signals to PLC rejection valves and automatically stops conveyor on repeated errors.

Barcode Verification FAQs

How does the Barcode Verification System prevent label mix-ups?

The camera scans passing carton or leaflet barcodes and compares decoded content against expected master values or SQL whitelists. If an incorrect label from a different batch is detected, the system fires the rejection valve or stops the conveyor.

Does it read rotated or inverted barcodes?

Supported decoder backends can be configured to search rotated and inverted symbols. Final performance depends on code quality, optics, lighting, resolution, and line speed.
