How to Make QR Code Anti-Counterfeit Labels: 5-Step Production Process + 7-Step Testing + 4 Case Studies
💡 💡 At a Glance
From Data Generation to Finished Product Delivery: A Detailed Guide to the Entire Production Process of QR Code Anti-Counterfeiting Labels
Last week, a client running a cosmetics brand asked me: "I want to apply an anti-counterfeit QR code label to each product. What's the process?"
I said: "5-step process + 7-step testing—running it through completely from code library to scan-code verification."
He said, "How exactly do we do it?"
I said: "5-step hands-on process—code library selection + printing + application + scanning + lookup. This article doesn't cover 'what is QR code anti-counterfeiting'—it covers the 5-step hands-on process + 7-step testing + 4 types of real cases + 5 common types of attacks."
5-Step Practical Workflow
Step 1: Select Code Library
3 Code Library Types:

- Third-party SaaS — fast + low cost
3 Key Elements:
- Uniqueness (each item different)
- Capacity (millions to billions)
- Scalability (upgrade support)
Step 2: Print Labels
3 Printing Methods:
- Digital Printing (under 1,000 sheets)
- Offset Printing (1,000–50,000 sheets)

5 Common Types of Attacks and Defenses
Attack 1: Direct Copying
Method: Scanning the genuine product + print copying
Defense:
- Unique code per item (database deduplication)
- Anti-transfer (invalidates when peeled off)
Attack 2: Replacing the Code Database
Method: Counterfeiters replace the code database
Defense:
- Blockchain (tamper-proof data)
- Multi-party signatures
Attack 3: Altering the Code
Method: Tampering with the numbers
Defense:
- Anti-counterfeit printing (color change upon alteration)
- Verification code (mismatch with the original code)
Attack 4: Mass Counterfeiting
Method: Mass production of fakes + code labeling
Defense:
- Code database integrated with the production system
- Genuine-product codes are unique (cannot be mass-produced)
Attack 5: Scanning and Copying the Genuine Product
Method: Scanning the genuine product's QR code + printing 1,000 copies
Defense:
- One-time scanning (invalidates after the first scan)
- Real-time data feedback (anti-counterfeit verification)
3 Key Quality Control Points
Control 1: Code Library Generation
3-Step Control:
- Uniqueness (unique database index)
- Encryption (AES 256)
- Audit log (record for every operation)
Control 2: Printing Quality

FAQ
How to Make a QR Code Anti-Counterfeit Label?
5-Step Practical Workflow: (1) Code library selection — choose GS1 global standard or build a custom code library (unique per item); (2) Label printing — digital printing + QR code (unique per label) + tamper-evident adhesive; (3) Product labeling — automatic labeling machine or manual application; (4) Consumer scanning — H5 pop-up (anti-counterfeit query + marketing campaign); (5) Data feedback — scan data → anti-counterfeit verification + marketing analytics. 3 Key Points: (1) Code library uniqueness (each item different); (2) Tamper-evident (invalidates if removed); (3) Backend data feedback (real-time verification + consumer profiling). 3 Cost Categories: code library ¥10,000–50,000 + labels ¥0.3–1 + system ¥50,000–200,000.
How does the QR code anti-counterfeit label prevent duplication?
5 Anti-Copy Measures: (1) Unique Code Library – each item has a different code (database deduplication + unique index); (2) Anti-Transfer – destroys upon removal (anti-counterfeiting code becomes invalid); (3) Dynamic Encryption – code content can be encrypted (DES / AES); (4) Blockchain – code library uploaded to chain (tamper-proof + trustworthy); (5) Multi-Technology Integration – QR code + RFID + blockchain. 3 Common Types of Attacks: (1) Code Copying – scan genuine product + print (most common); (2) Code Replacement – counterfeiter replaces code library (requires blockchain defense); (3) Code Alteration – alters numbers (requires anti-counterfeiting printing + check code). 3 Types of Defense: unique code + anti-transfer + dynamic encryption.
QR Code Anti-Counterfeiting Label Testing Method?
7-step Test Verification: (1) Scanning test—100 samples scanned 100 times (recognition rate 100%); (2) Code library test—duplicate check (0 duplicates); (3) Anti-transfer test—tear off 10 labels (all 10 become invalid); (4) Encryption test—attempt reverse decoding (cannot be deciphered); (5) Database stress test—100,000 queries (response < 1 second); (6) Concurrency test—1,000 simultaneous scans (no lag); (7) Attack simulation test—replicate genuine products 100 times (100% identified as counterfeit). 3 Test Tools: scanning test instrument (RMB 100) + stress testing tool (professional RMB 10,000+) + penetration testing (professional RMB 50,000+). 3 Verification Standards: (1) scanning rate 100%; (2) anti-counterfeiting 100% effective; (3) system stability.
How much does a QR code anti-counterfeiting label cost?
3 Budget Tiers: (1) Small—50,000–100,000 (code database 10,000–30,000 + labels 0.3–0.5 yuan + system SAAS 10,000–30,000/year); (2) Medium—100,000–500,000 (code database 50,000–100,000 + labels 0.5–1 yuan + custom system 50,000–300,000); (3) Large—500,000+ (code database 100,000+ + labels 1–3 yuan + self-built system 300,000–1,000,000). 3 Types of Cost Savings: (1) Shared code database—multiple companies sharing one 10,000-entry code database (cost-sharing); (2) Digital printing replacing offset printing (30% cheaper for orders under 1,000 sheets); (3) SAAS replacing self-built (faster launch + lower investment). 3 Types of ROI: (1) 100% anti-counterfeiting—avoid counterfeit losses (typically 5–10% of annual revenue); (2) +20% marketing—scan-code traffic diversion + repeat purchases; (3) Data assets—consumer profiling + decision support.
How to use blockchain for anti-counterfeit QR code labels?
3-Step Integration: (1) Select blockchain—public chain (Ethereum / AntChain / Chang'an Chain) or consortium chain (AntChain BaaS); (2) Code library on-chain—unique code + production information (time / batch / factory) written to blockchain for each item; (3) Query & verification—consumer scans code → check on-chain data → compare authenticity. 3 Core Advantages: (1) Tamper-proof data (blockchain feature); (2) Full traceability (each node on-chain); (3) Multi-party trust (no centralized authority needed). 3 Investment Categories: (1) Blockchain platform—public chain free (gas fee) / consortium chain 10,000–100,000 RMB/year; (2) Integration development—50,000–300,000 RMB (one-time); (3) Operating cost—gas fee 0.001–0.01 RMB/query. 3 Applicable Enterprise Categories: (1) High-end brands (luxury goods / alcohol & beverages / pharmaceuticals); (2) High compliance requirements (FDA + China Food and Drug Administration); (3) High-trust scenarios (finance / government affairs).
