쿠폰 및 프로모션용 QR Code

QR Codes for Coupons and Promotions

QR code coupons combine the immediacy of physical distribution with the trackability and fraud prevention of digital systems.

Single-Use vs Multi-Use

Multi-use QR codes: One QR code printed on many flyers, each linking to the same discount page. Simple but no fraud prevention — the code can be shared infinitely.

Single-use QR codes: Each printed piece has a unique QR code linking to a unique coupon code. Provides: - One-time redemption enforcement - Individual tracking - Fraud prevention - Personalised offers

Coupon QR Code Architecture

The typical flow:

1. Generate unique coupon codes in your e-commerce or POS system
2. Create dynamic QR codes or unique static URLs for each code
3. Print QR codes on flyers, direct mail, or packaging
4. Customer scans → enters coupon code (or it auto-applies via URL)
5. System validates: unused, not expired, matches conditions
6. Discount applied at checkout

Expiration Management

• Encode the expiration date in the URL or landing page
• Dynamic QR codes can redirect to an "expired" page after the deadline
• Display "Valid until [date]" alongside the QR code in print
• Server-side validation is the definitive check — never rely on client-side date checking

Fraud Prevention

Distribution Channels

• Direct mail: Highest personalisation, highest cost per piece
• In-store flyers: Grab-and-scan at point of purchase
• Product packaging: Reorder discounts inside the package
• Event handouts: Time-limited offers at trade shows and conferences
• Receipt printing: Post-purchase coupons for return visits

Key Takeaways

• Single-use QR codes prevent unlimited sharing and enable tracking
• Server-side validation is essential for expiration and fraud prevention
• Dynamic QR codes enable post-print expiration and URL management
• Combine QR coupons with account login for strongest fraud prevention
• Always display expiration dates alongside the QR code in print
