Step-by-Step Process:

1. User Action: The customer opens the Blerify app and scans the merchant’s QR code.
2. Merchant System: The cashier registers the transaction amount in their POS system.
3. Voucher Selection: The user selects the desired voucher and submits the payment request.
4. Code Generation: The app generates a unique 6-digit code for the transaction.
5. Merchant Validation: The cashier enters the code in their system and triggers a call to the Blerify API.
6. API Verification:
   • The API checks the validity of the code, ensuring the transaction is in a pending state.
   • If valid, the API confirms the transaction and marks the voucher as redeemed.
7. Final Notification: Both the customer and merchant are notified of the successful transaction.
