The financial landscape has changed drastically in our fast-paced digital age. We are no longer constrained by physical currencies or unwieldy checkbooks. The age of electronic payment systems, or e-payment systems, has arrived.

In this guide, you’ll learn how electronic payment systems work and the different types that exist. We start with the basics and then go into detail.

What is an electronic payment system?

An electronic payment system is a digital platform or mechanism that facilitates the transfer of money or funds between parties electronically. It allows individuals, businesses, and organizations to make and receive payments using electronic devices such as computers, smartphones, or tablets, instead of traditional cash or checks. 

Electronic payment systems encompass a wide range of payment methods, including credit card payments, bank transfers, mobile wallets, peer-to-peer transfers, and online payment gateways, providing convenient, secure, and efficient alternatives to traditional payment methods.

The popularity of electronic payment services

E-payment systems are indispensable in today’s digital economy, driving efficiency, security, and innovation across various sectors. From online shopping to international commerce, these various online payment systems enable seamless transactions, foster economic growth, and promote financial inclusion on a global scale.

• According to estimates, the total transaction value in the digital payments segment is set to reach $9.46 trillion by 2023. 
• It is expected that the digital payments market will continue to grow and will reach a value of $14.78 trillion by 2027. 
• The digital commerce segment is currently the largest in the digital payments market

How do electronic payment services work?

The electronic payment system (EPS) is a series of interconnected payment processes that allow for the electronic transfer of funds between parties. Here’s how it typically works:

1. Initiation

The payment process starts when a payer authorizes a transaction. This can be done online, by swiping a card at a point-of-sale terminal, or through other means like mobile apps or digital wallets.

2. Authorization

Once the payment is initiated, the EPS verifies the payer’s identity and ensures that they have enough funds or credit available to complete the transaction. This step may involve authentication measures like passwords, PINs, biometrics, or two-factor authentication for added security.

3. Transmission

After authorization, the payment details are transmitted securely from the payer’s device or card terminal to the payment processor or acquirer. The payment processor then acts as an intermediary between the payer’s bank (issuing bank) and the payee’s bank (acquiring bank).

4. Routing

The payment processor routes the transaction data to the respective banks involved in the transaction, including the payer’s bank to deduct the funds and the payee’s bank to credit the funds.

5. Settlement

Once the banks approve the transaction, the funds are transferred from the payer’s account to the payee’s account. This can happen in real-time (instant payments) or be batched and settled at predetermined intervals.

6. Confirmation

Upon successful settlement, the payer and payee receive confirmation of the transaction, usually in the form of a receipt or notification from their respective banks or payment providers.

7. Recordkeeping

The EPS keeps a record of the transaction details, including the amount, date, time, and parties involved, for auditing, reconciliation, and dispute resolution purposes.
