How the payment system works
The process of processing a payment through an electronic payment system consists of several important stages:
1. Choosing a payment method
The user has the opportunity to choose the most convenient payment method, including a bank card, e-wallet or contactless payments via Apple Pay or Google Pay.
2. Transferring data to the payment system
The system generates a special secure request that contains all the necessary information about the current transaction.
To ensure maximum security, all data is transmitted over a secure connection using the modern TLS encryption protocol version 1.2 or higher.
3. Payment process
After choosing a payment method, the user is automatically redirected to a special secure page to make a payment.
On this page, the user enters the necessary payment data or is authorized through his e-wallet.
For additional transaction security, the system authenticates the user using 3D-Secure technology.
4. Transaction processing
The payment system for the website performs a comprehensive check of the availability of funds on the account and the correctness of the entered data.
Each transaction goes through the anti-fraud monitoring system to identify potential fraudulent activities.
The bank that issued the card conducts the final check and makes a decision to confirm or reject the payment.
5. Payment completion
Immediately after the transaction is completed, the system sends a notification to the user about the status of his payment.
The online store receives an automatic confirmation of the successful transaction.
The system automatically generates an electronic receipt and stores detailed information about the payment in the transaction history.
When choosing electronic payment systems in Ukraine, it is necessary to take into account not only the technical aspects of integration, but also the convenience of the interface for users, fast Particular attention should be paid to data security and availability of round-the-clock technical support.
