# Redeemption
It allows customers to redeem vouchers seamlessly while ensuring that merchants can validate and confirm transactions in real-time. Below is a step-by-step guide and a detailed summary of the process.
### **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.
