Digital Coupon

Digital coupons replace paper coupons with smartphone-based electronic data. They offer zero printing costs, unlimited distribution, real-time usage tracking, and easy expiration management.

QR codes participate in the entire digital coupon lifecycle: distribution (scanning poster/flyer/social media QR codes to acquire coupons), presentation (showing coupon QR codes at checkout), and redemption (store scanning to mark as used, preventing double-use).

Dynamic QR codes enable time-based coupon variation - weekday 20% off, weekend 10% off, rainy day specials - without reprinting. Anti-fraud measures include one-time tokens verified server-side and dynamically refreshing QR codes that prevent screenshot forwarding.
