What Is a 2D Payment Gateway?

A 2D payment gateway is an interface for online clients to accept payments by securely entering their basic card information. This includes details such as the card number, expiration date, and the CVV (Card Verification Value) code provided by the card issuer or issuing bank. The CVV acts as an additional security measure to ensure that the cardholder has the physical card. Once the customer inputs the required information, the 2D gateway initiates the payment process instantaneously. It securely transmits the transaction details to the respective card networks and acquires banks for authorisation. The card networks communicate with the customer’s issuing bank to verify the transaction and ensure there are sufficient funds.

If the transaction is approved, the funds are immediately debited from the customer’s bank account, completing the payment process. The 2D payment gateway plays a crucial role in facilitating this seamless and secure transfer of funds between the customer’s bank account and the merchant’s account. By providing a simple and intuitive interface and incorporating robust security measures, the 2D payment gateway offers a convenient and reliable payment solution for online businesses. It enables customers to make payments quickly and efficiently while ensuring the confidentiality and integrity of their sensitive card information.

How 2D Payment Gateways Work?

Here is a comprehensive explanation of how 2D payment gateways work:

  1. Customer Initiates the Payment: Customers visit the merchant’s website or app and select the products or services they wish to purchase.
  2. Payment Details Entered: At the checkout page, the customer enters their payment information, including the card number, expiration date, and CVV code. Some gateways may require additional information, like the cardholder’s name and billing address.
  3. Encryption and Data Transmission: The payment gateway uses encryption technology, typically SSL (Secure Sockets Layer) or TLS (Transport Layer Security), to secure the customer’s payment information. This ensures that the data is transmitted securely between the customer’s device and the gateway’s servers, protecting it from unauthorized access.
  4. Authorisation Request: Once the customer submits the payment information, the payment gateway sends an authorisation request to the acquiring bank or payment processor. The request includes the transaction details, such as the amount, merchant information, and customer payment information.
  5. Verification Process: The acquiring bank or payment processor forwards the authorisation request to the respective card network (such as Visa, Mastercard, etc.). The card network then routes the request to the customer’s issuing bank for verification.
  6. Issuing Bank Response: The customer’s issuing bank receives the authorisation request, verifies the card details, and checks for available funds or credit limit. The bank performs various security checks to detect any suspicious activity or fraud. The bank sends an authorisation response back to the payment gateway via the card network based on the verification results.
  7. Transaction Approval or Decline: Upon receiving the authorisation response from the issuing bank, the payment gateway determines whether the transaction is approved or declined. The transaction is approved if the customer has sufficient funds or credit available and the card details are valid. Otherwise, it is declined.
  8. Payment Completion: If the transaction is approved, the payment gateway notifies the merchant, allowing them to proceed with order fulfilment. The customer’s funds are reserved or marked for capture, meaning they will be deducted from their account once the settlement begins.
  9. Settlement and Funds Transfer: The payment gateway initiates the settlement process, where the funds are transferred from the customer’s bank account to the merchant’s account. Settlement may take place within a specified timeframe, depending on the agreement between the merchant and the payment gateway. The settlement process involves the movement of funds between various banks and financial institutions.
  10. Transaction Record-keeping: The payment gateway records all transactions processed through its system. This includes storing transaction details, authorisation codes, timestamps, and other relevant information. The transaction records are valuable for both the merchant and the customer, as they provide a reference for order tracking, reconciliation, and dispute resolution if needed.

Throughout the entire process, 2D secure payment gateways prioritise security by using encryption, tokenization, and compliance with industry standards such as PCI DSS (Payment Card Industry Data Security Standard). These measures protect the customer’s payment information from unauthorized access and fraud.

Which Is Better 2D Payment Gateway or 3D Payment Gateway?

A 2D payment gateway offers simplicity and convenience. It allows customers to make payments by manually entering their card information, resulting in faster transactions. This type of gateway is widely accepted and easy to implement. However, it may be more susceptible to fraudulent activities since it lacks an additional layer of authentication. Merchants using a 2D payment gateway bear the responsibility for chargebacks and fraud.
On the other hand, a 3D payment gateway prioritizes security and customer trust. It incorporates an extra layer of authentication, such as one-time passwords (OTP) or password-based authentication, reducing the risk of fraudulent transactions. With a 3D payment gateway, liability for authorized transactions shifts to the card issuer, alleviating the merchant’s burden. However, the payment process may take slightly longer due to the authentication step.

Ultimately, the choice between the two depends on the level of security, risk tolerance, and customer experience you prioritize. If you value simplicity and faster transactions, a 2D payment gateway may suffice. But if you prioritize security and customer trust, a 3D payment gateway is the better option.


In conclusion, 2D payment gateways have revolutionised the world of online transactions, offering a range of benefits for businesses and customers alike. With their user-friendly interface and simplified payment process, they ensure seamless and secure transactions, saving time and effort for both parties. Businesses can expand their customer base and enhance customer satisfaction by providing a convenient platform to accept payments. Moreover, the robust security measures of 2D payment gateways instill confidence in customers, mitigating the risk of fraudulent activities.
