From Lot to Individual: Complete Traceability with GAZIRU.eye and GAZIRU.z
The "norm" of quality control in manufacturing is about to change. Complete traceability at the individual product level—impossible with conventional lot management—is now achievable through the integration of GAZIRU.eye and GAZIRU.z.
1. The "Invisible Wall" of Lot Management
When a recall occurs, can you accurately identify which products are actually defective?
Most manufacturers have no choice but to answer "NO" to this question.
Traditional manufacturing has managed products by lot. A single lot contains hundreds to thousands of products. However, even when defects are found in some products, identifying exactly which products within the lot are defective is extremely difficult.
As a result, recalls require retrieving the entire lot—including products with no actual problems—leading to enormous costs and loss of customer trust.
Even more serious is the inability to determine "why defects occurred." Since quality data is only aggregated at the lot level, detailed analysis at the individual product level is impossible, making root cause identification and process improvement extremely challenging.
2. When Two Technologies Meet
The solution to this challenge lies in the integration of GAZIRU.eye (anomaly detection) and GAZIRU.z (individual identification).
GAZIRU.eye: AI That "Detects" Anomalies
GAZIRU.eye is an AI anomaly detection software. Its greatest feature is the ability to learn from just a few dozen normal images. While conventional AI inspection requires thousands to tens of thousands of defect images, GAZIRU.eye can be rapidly deployed even in high-mix, low-volume production environments.
Detected anomalies are visualized as heatmaps, clearly showing "where" and "what kind of" anomalies exist.
GAZIRU.z: Technology That "Remembers" Products
Meanwhile, GAZIRU.z (individual identification) reads a product's "fingerprint" from the micrometer (μm) level micro-patterns that naturally exist on product surfaces.
No tags or engravings required. Products can be identified without compromising aesthetics, even for ultra-small components.
3. Three Innovations Created by Integration
What happens when these two technologies are integrated?
✅ 1. Complete Traceability at the Individual Level
By linking inspection results to individual products, records like "Product A-12345: 0.3mm scratch detected on surface at 14:23 on December 18, 2025" are maintained.
During recalls, only the problematic products can be precisely identified. No more retrieving entire lots.
✅ 2. Data-Driven Process Improvement
By accumulating quality data for each individual product, previously invisible patterns emerge.
- "Products manufactured on Friday afternoons tend to have slight coating irregularities"
- "Parts processed on specific equipment have higher rates of micro-scratches"
Truths invisible at the lot level become clear from individual data.
✅ 3. Transparent Quality Assurance for Customers
"Can you show me the inspection results for this product?"
You can respond to this customer request immediately. Anomaly detection data at shipment, inspection date and time, inspector—everything is stored linked to the individual product.
Transparency in quality assurance strengthens trust relationships with customers.
4. Made Possible Because It's Tagless
The strength of this integrated solution lies in the fact that both technologies are tagless.
QR codes and RFID tags cannot be applied to small components. They compromise aesthetics on luxury goods. They cannot be used on food products.
Both GAZIRU.eye and GAZIRU.z require no physical modification to products. Anomaly detection and individual identification are completed simply by "looking."
Individual-level traceability is now achievable in previously impossible domains—ultra-small components, luxury goods, and food products.
5. Why Only GAZIRU Can Provide This
"Why not just combine an anomaly detection system with an individual identification system?"
Theoretically possible. But in reality, integrating systems from different vendors requires enormous cost and time. Different data formats, complex API integration, duplicated maintenance—the challenges are endless.
GAZIRU's solution is designed so that both functions seamlessly integrate. Deployment and operation are simple.
Companies possessing both technologies are limited worldwide. GAZIRU is one of those few.
6. The Future of Manufacturing Begins with the Individual
As global competition intensifies and quality requirements become more sophisticated, DX in manufacturing is unavoidable.
However, DX is not mere digitization. It's about leveraging data to transform business.
From lot-level quality control to individual-level quality control—this transition will determine manufacturing competitiveness.
Expected Benefits
- Dramatic reduction in recall costs
- Continuous quality improvement
- Enhanced customer trust
- Readiness for the EU's Digital Product Passport (DPP)
Everything begins with individual-level traceability.
The integration of GAZIRU.eye and GAZIRU.z is not just a combination of technologies. It is a next-generation solution that transforms the very nature of quality assurance in manufacturing.
