Whether you offer a 3D or 2D payment gateway to your online store, consumers always want the fastest but most secure transaction.
Customers are always pressing on. So you’ve got to cope with this and try your best to provide the simplest solution.
According to Statista, the total transaction value in the digital payments market is projected to reach US$11.55 trillion in 2024. Various types of online payment gateways will be involved to make this happen.
So in this article, we’ll talk about a 2D payment gateway, exploring its features, benefits, and what makes it different from a 3D payment gateway.
What is a 2D payment gateway?
A 2-Dimensional Secure, also known as 2D Secure payment gateway, is the simplest form of payment authentication that requires the least amount of information to complete any online transaction.
Without any additional security checks or entering any OTP, consumers can pay by inputting their basic card details, like their card number, expiration date, and CVV number.
PayPal, Stripe, PayU, and Braintree are widely popular as both 3D and 2D payment gateways because of the convenience they bring.
Specifically, Authorize.Net is the most popular and considered the best 2D payment gateway in USA.
Benefits of a 2D payment gateway

With seamless checkout experiences and swift transaction processing, a 2D payment gateway empowers businesses to enhance customer satisfaction and boost sales. It eliminates the need for additional authentication and makes payment processing effortless.
Let’s have a look at what it brings to your businesses:
- Enhanced user experience: 2D payment gateways offer a seamless and user-friendly checkout experience for customers, allowing them to complete transactions quickly without the hassle of additional authentication steps.
- Improved conversion rates: Streamlining the payment process and reducing friction during checkout, it can help businesses increase their conversion rates and drive sales.
- Faster transaction processing: With a 2D payment gateway, transactions are processed rapidly, enabling businesses to receive payments promptly and improve cash flow.
- Cost-effective solution: Compared to a 3D payment gateway, which may involve higher transaction fees and additional authentication costs, a 2D payment gateway offers a more cost-effective payment processing solution for businesses of all sizes.
- Global accessibility: If you want to expand your business to worldwide markets, a 2D payment gateway for international payments can make a significant impact. Because it supports transactions in multiple currencies.
Differences between 2D and 3D payment gateways

While both 2D and 3D payment gateway facilitate online transactions, there are some dissimilarities in terms of authentication methods and security features. The key difference is receiving OTP through SMS or email.
Where a 2D payment gateway without OTP allows you to complete your transactions by just inputting the basic card information, in a 3D payment gateway, you’ve got to input the OTP in addition to the card details to make your payment.
A 2D payment gateway company makes the process smoother and faster, whereas 3D payments are also quick, but you may have to wait for a longer period of time, as sometimes the OTP does not arrive in real-time due to network issues.
Which can easily irritate a customer and lead them to abandon the purchase as well.
3D payment gateways are more secure, as they’ve got an extra layer of security, but that doesn’t mean 2D payments are not secure at all. Most of them are PCI-DSS compliant and have end-to-end data encryption systems.
The extra verification of 3D payment systems may provide a less user-friendly experience for users, but they offer peace of mind by protecting them from potential fraudulent activities. Which is applicable for both businesses and customers.
Conversely, with 2D payment gateway sites, the absence of such verification leaves users vulnerable to the risks of fraudulent transactions.

Which can’t be done in any online shop that uses a 3D payment gateway.

- PCI compliance: Ensure that when using a payment gateway, it complies with PCI-DSS requirements to protect cardholder data and maintain the trust of your customers.
