How to Correctly Incorporate a Mobile Payment Gateway into an E-Commerce App

In 2023, approximately 73% of individuals completed online purchases using their mobile devices, according to Statista. Additionally, just 6.5% of the value of all e-commerce transactions in 2019 were made using mobile devices. However, by 2023, 44.5% more people were using mobile payment gateways!

Nowadays, in-app payments are available in practically all apps. Why? Because clients value how easy it is to make a purchase without having to log into their bank accounts or enter their credit card details.

However, while the majority of us are aware of how to use an app for payments, few of us are likely aware of how these apps function technically or what’s required to incorporate them. Do you too have that question in your mind? You’ve come to the correct place because in this article we’ll discuss adding a payment gateway to an app and why you should.

A Mobile Payment Gateway: What is it?

Mobile payment gateways enable both sellers and buyers to embrace online payments for transactions made through an app. Transaction information from the consumer is received, processed, encrypted, verified, and transferred from the gateway to the merchant. Fundamentally, the payment gateway software serves as a conduit for financial transactions between customers and retailers.

The general flow of the payment process is as follows:

  • An online shopper selects the item they wish to buy and puts it in their cart.
  • The consumer selects their preferred payment option during the checkout, such as a bank app code or credit card. They are then forwarded to a gateway webpage, such as PayPal (but there are numerous others; we’ll mention those later).
  • The gateway sends the bank the user-added information.
  • The issuing bank verifies the validity of the transaction and confirms that the buyer has sufficient funds in their accounts to complete the transaction.
  • The payment confirmation is returned to the app via a payment gateway if the validation is successful.
  • The seller then learns that an order has been placed and paid for.
  • Finally, a payment settlement is started by the gateway, and the merchant then sees the funds in his account.

Is it surprising that fewer individuals are utilizing actual currency or banknotes given that it just requires a few seconds for the payment to be completed, even if it may feel like a lengthy and onerous process? Only 9% of individuals in the Asia-Pacific area used physical money in 2019, and that percentage is projected to drop to 1.6% by 2024.

By 2025, it’s anticipated that, say, Poland’s mobile payment market would be worth US$26,893.9 million. The BLIK service, which enables clients to pay for their purchases and make withdrawals using only their mobile banking app and a special 6-digit code issued during each transaction, is mostly deserved for this.

What Advantages Do Mobile Payment Gateways Offer?

If you currently have or want to develop a mobile application, you’re undoubtedly aware of the fierce competition in the market and the challenges of retaining users. Your app can be largely superseded by another one if you don’t stay on top of the most recent developments in the market. Digital wallets are already by far the most popular means of payment in the Asia-Pacific region, in which it’s anticipated that they’ll account for 47.9% of POS transactions in 2024. Mobile payments are one of these developments.

But why are they worth so much? Mobile transactions are tremendously convenient, to start with. Customers can make purchases even from a distance without having to carry currency or worry about finding change (such as paying for a takeaway as they are leaving their workplace).

For companies, this means:

  • Increased consumer satisfaction as a result of a payment process that’s considerably more convenient and the availability of items and services around-the-clock.
  • Increased customer loyalty and retention as customers are pleased with their shopping.
  • Much safer transactions since data is encrypted and put via fraud prevention software as it flows between gateways. Digital wallets also offer additional biometric identification layers, such as fingerprint and/or facial recognition scans, to help businesses make sure that payments are legitimate.
  • A chance to expand your company internationally since payment gateways make it possible for customers from all around the world to purchase your goods or services.
  • Transactions that are declined are automatically allowed or denied, so there’s no need for you to manage them yourself.

The fact that payment gateways lower the risk of fraud should pique your interest as a business owner:

  • Only the consumer and their issuing bank have access to the full number because it is encrypted as it is sent from the customer’s card or bank to the payment gateway.
  • To ensure the privacy of your clients’ card information, a payment processor must be compatible with PCI DSS requirements, which implies it must adhere to particular security criteria.
  • For each card a consumer uses to make an online purchase, card services offer the 3-D Secure extra security protocol, which necessitates the usage of a one-time password.

The final advantage is that including a mobile payment gateway in your new app can greatly increase your revenue. According to Statista, the transfer value generated by smartphone payment apps will hit around $14 trillion by 2023; if you want a piece of that enormous revenue, setting up a mobile payment processor is an absolute must.

But, now they’ve realized that was wrong they race against each other in agreeing to collaborate with serious online sportsbooks, like those at Bookmaker-Expert.com, and casinos.

  • How many nations does the provider service? (and can it accept foreign currencies).

  • Offered integrations.
  • PCI DSS and PSD2 standards adherence.
  • Accessible customer service.

  • Integrate client- and server-side SDKs.
  • Join the API.
  • Get a certificate for payment security.

This final step is very important because your server processes payment information directly and as a result must also adhere to PCI-DSS regulations. You need to complete two steps in order to get this certificate. In this situation, you must first analyze all of your information systems that retain card data and address any issues that are discovered. Following an assessment by one of the PCI Security Standards Council businesses, your business will receive certification and be able to start accepting payments.
