As a result, the active growth of digital payment methods opens up new opportunities for businesses to attract users and increase profits. Using innovative technologies you can create a financial application to meet customers’ and business needs. In this article, we highlight the modern payments stack that is driving the development of the financial industry and improving business efficiency.
What is a payment stack?
Payments stack is a set of technologies that are utilized to build payments software. It is a complex of programming languages, frameworks, and tools used to create a seamless commerce experience for businesses, financial institutions, and customers.
The finance stack describes the combination of all the technical infrastructure you need to develop payment solutions. These technologies allow making payment requests, offer P2P transfers, managing transactions, and currency exchanges.
Every step of a consumer’s purchasing process is covered by a payment stack, including the types of payments that are accepted and where transactions are sent for validation, processing, and settlement. Companies using new technologies accelerate financial operations, such as annual planning, accounting, reporting, and analytics, which are managed through automation capabilities.
Technology trends that are driving the payment industry
The payments industry is growing considerably and 2023 will be a year of launching a new fintech stack. Users need flexible cashless services, including digital wallets, real-time payments, and mobile banking versions. According to Statista, the largest fintech market segment is digital payments. It generated a transaction value of $4.4 million in 2020, an amount that is likely to double by 2024.
Therefore, the demand for digital transactions affects the spreading of the modern payment tech stack. There are several technology trends driving the financial business: artificial intelligence, machine learning, payment APIs, cloud computing, and robotic process automation.
In the financial sector, it is extremely important to provide a high level of security for all payments and banking services. To provide fraud prevention companies use AI and ML algorithms to analyze millions of data points, transaction parameters, and consumer behavior patterns in real time. It allows the detection of security threats and potential fraud cases.
Machine Learning can be applied to payments to respond rapidly to known and emerging patterns of fraud, and to detect patterns of fraud that may not otherwise be identified.
Artificial Intelligence and Machine Learning
Artificial intelligence and machine learning are also used to perform high-volume transactions and anticipate online payment frauds. By processing multiple data sources in real-time, these technologies can allocate traffic to the best-performing combination of variables at any point in time. As a result, it helps PSPs optimize payment routing based on multiple parameters, such as performance, functionality, or pricing.
By using ML and AI algorithms for biometric authentication you can prevent identity theft. This tech trend allows you to improve business effectiveness and make performance more automated. For instance, the Japanese bank is going to cut about 19 thousand jobs by 2026 and replace them with AI technologies to be more efficient than its competitors and gain higher profits. It also helps to improve user satisfaction rate, providing better customer support service.
