RTP, FedNow, or Both!

Well, if you’re looking to implement RTP or FedNow services, learning about them all is an important step to undertake.

Real-time payments (RTP) refer to the instant fund transfer and are helpful to businesses to receive and send funds successfully. However, FedNow is an instant payment infrastructure that allows banks and credit unions to allow financial institutions to send and receive money.

In this detailed guide on RTP and FedNow, you can explore the rise of RTP, its working process, implementation steps, and differences.

Hence, without further ado, let’s begin.

The Rise of RTP and FedNow

Before you directly jump into understanding the RTP and FedNow, it’s important to evaluate where it all began.

The clearing house’s real-time payments network was the first payments network in the United States to offer near instant settlement and clearing.

In 1973, Japan’s Zengin system started processing payments in real-time, although it went 24/7 in 2018. It was further followed by Switzerland in 1987; this pace picked up after the turn of the 21st century.

Later, India launched its rapidly growing Unified Payments Interface real-time payments platform in 2016, which had the largest volume of payments with over 129.3 billion transactions.

When it comes to FedNow, these services went live on July 20, 2023, and are available to depository institutions in the United States, which enables businesses and individuals to send instant payments via their depository institution accounts.

The birth of RTP was in 2017, and FedNow steps in 2023; they are considered as two trails, and one evolution.

If you are building a banking app, proceeding with the real-time payments, or FedNow services, and even both, is essential.

Now, let’s get ahead with learning them.

What is RTP (Real-Time Payments)?

Real-time payments are instant funds transfers that provide near-instant money availability via payment networks that do operate around 24/7.

Unlike the traditional payment systems, which can take hours or days to complete a single transaction, the RTP systems can be used to transfer funds from one bank account to another immediately.

It further improves transparency and confidence in payments, helping consumers, banks, and even businesses manage their money. These systems are designed to enhance transactions and are initiated, cleared, and settled within seconds at any time of the day or week, including holidays and weekends.

One of the important roles of RTP is to optimize the complete cash flow, enhance overall liquidity, and then improve the complete customer experience via immediate payment confirmation. This is also a crucial mobile banking app feature that you cannot ignore for your app.

How Does RTP Work?

RTP goes through a complete working procedure, starting from payment initiation, authentication, request routing, interbank communication, and then settlement between the banks.

Let’s learn the complete working process below:

1. Payment Initiation

The first step that RTP takes is payment initiation via the digital banking platform, such as a bank website, and even the payment amount. It includes a transfer request that has been submitted by the payer and received by the bank.

Here, the payer provides details related to the recipient’s bank accounts. This might include the traditional account numbers or even modern aliases such as mobile numbers or email addresses, and even QR codes.

2. Bank Verification

This is the security step undertaken by banks where a financial institution confirms the translation details, account ownership, and even fund availability. Additionally, the bank confirms that the account has sufficient funds for transfer.

It is a process of confirming that a bank account is authentic, active, and even belongs to the person or business claiming ownership. Here, the verification was made via a two-factor authentication system.

3. Network Processing

Network processing in the context of RTP refers to the core infrastructure that enables the instantaneous clearing and settlement of funds directly between institutions.

The key aspects of network processing include real-time credit transfers with enhanced data capabilities. The RTP’s process transactions individually and even continuously, helping the systems to handle transactions.

4. Instant Confirmation

Even after the payment is processed, the payer and the receiver receive a payment confirmation notification or a payment failed notification, based on the RTP’s network processing.

This notification can be received via email, SMS, or even through the push notification from a banking app, depending on how the payment was initiated.

5. Settlement

Settlement is the last step in the RTP process. Unlike in traditional payment systems, which occur at the end of the day, in RTP, settlement happens almost immediately.

Here, the payer’s bank transfers funds to the payee bank, and the money gets immediately available for use in the payee’s account.

Now, if you are a business owner or an investor, thinking of getting ahead with the RTP app, it is the right time. In this guide to RTP and FedNow, we have covered it too.

How to Create an RTP App in 2026?

You can create an RTP app beginning with planning, securing RTP-enabled accounts, integrating payments APIs, and implementing the core technologies, further you need to get ahead with security and testing landscape.

Now, you should proceed with integrating the payment APIs. Here, you should use the financial services APIs to facilitate the bank account linking and verification, and payment routing.

All you need is to select the right API provider, or hire mobile app developers, who can not only build your RTP app, but can also find the right API services for your app.

Step 4: Implementing the Core Technologies

After evaluating APIs, you should examine the fintech app tech stack. These technologies comprises of flutter and react native for the frontend, Java, Python, and Go for the backend.

Along with this, you should use PostgreSQL and MySQL for the relational databases, helpful for handling large volumes of data in networks.

Step 5: Testing and Launch

This is the last step in the process to create an RTP app, which requires simulating the network conditions and validating packet streams via tools for ensuring low-latency delivery. You can proceed with the fintech app testing landscape and can ensure auditing.

Under testing, you get through multiple testing landscapes such as performance testing, compatibility testing, functional testing, and even usability testing. Further, you can launch it on the defined platforms.

After evaluating the RTP, let’s learn about FedNow in this detailed guide on RTP and FedNow.

What is FedNow?

The FedNow service is a new instant payment structure developed by the Federal Reserve that allows eligible depository institutions of diverse sizes across the U.S. to provide real-time payment services.

At the most fundamental level, this service does provide interbank clearing and settlement that enables funds to be transferred from the sender’s account to the receiver’s account in real-time.
