FAQ

chker is a mobile app that uses AI and blockchain to verify the authenticity of products. By scanning a QR-style code on a product, users can instantly check if it’s genuine or counterfeit.

chker is solving the growing problem of product counterfeiting, which causes over $500 billion in global losses annually and poses serious health risks to consumers. From fake cosmetics and food to counterfeit medicines, these products lead to illness, mistrust, and brand damage. chker uses blockchain and AI to ensure every product can be verified instantly — protecting both brands and buyers.

chker is a next-generation product authentication system that combines tamper-proof blockchain identity, AI-powered packaging analysis, and end-to-end supply chain tracking to stop counterfeits, including refill fraud and repackaging.

Each product is assigned a unique blockchain code at the factory — a digital fingerprint that is unforgeable and permanently logged. This code is embedded into a secure QR-style label and scanned at every stage of the product's journey:

• Manufacturing: Original product state is recorded (e.g., batch ID, factory, date)

• Logistics: Every checkpoint (customs, warehouse, distributor) adds to the blockchain record

• Retail: The product’s scan confirms if it followed a trusted path

• Customer: Final scan verifies authenticity and packaging condition using AI

Refill & Reuse Protection

chker detects refilled or repackaged items by flagging codes that have already been scanned. If a used container is resold with fake contents, our blockchain will show its prior lifecycle, and AI will inspect for tampering, like broken seals or worn print.

AI at Every Stage — Going Beyond Scanning

Our unique AI models go far beyond visual checks:

1. Packaging Defect Detection: Detects faded print, missing seals, or font mismatches — even before products leave the factory.

2. Refill/Reuse Fraud Analysis: Identifies reused packaging and inconsistent scan behavior across regions.

3. Tamper Detection: Analyses cap tightness, ink wear, or glue residue to estimate tampering likelihood.

4. Predictive Risk Alerts: AI analyses scan patterns and logistics data to predict regions or vendors where counterfeit activity is emerging.

5. Fake Web & Marketplace Monitoring: Detects and alerts brands to unauthorized e-commerce or social media resellers using your name.

6. Consumer Behavior Insights: Brands see where, when, and how users are scanning their products — unlocking market intelligence.

7. Voice-Based Verification (Accessibility): Enables visually impaired users to verify authenticity using voice feedback.

8. Sustainability & Lifecycle Scores: AI estimates environmental footprint and flags “reused” or “eco-packaged” products for consumer awareness.

9. Counterfeit Deterrence Messaging: If a fake is scanned, chker generates dynamic legal or warning messages in local languages to deter fraud.

10. Brand Agent Assistant: An AI co-pilot that alerts brands to fraud spikes, suggests actions, and generates reports.

In short, chker ensures that every product scan is backed by verified origin, traceable movement, and intelligent AI protection.
