Main Use Cases
QR codes are actively used for payments in restaurants, stores, and cafes. Also used in e-tickets for events, transportation, museums, and exhibitions.
Payment Code Types
QR payment acceptance requires integration with payment systems. Special standards are used (in Russia — SBP for online payments). The code is generated dynamically for each transaction.
QR Payment Security
Each payment QR code must be one-time use and have limited validity time. Payment data encryption is used. Financial data is not transmitted in the code itself.
Entry Checks
For tickets, the QR code is scanned at event entry. The system checks validity, date, seat, and entry count. Duplicates are blocked automatically.
Tips for Developers
Use high error correction level (ECC Level H). Add a unique identifier to the code. Integrate with ticket and payment management systems via API.
