Payment gateway vs payment processor in Singapore: Key differences explained

The Asia Pacific payment gateway market is one of the fastest growing networks in the world. This translates to scope and momentum when you use payment gateways and payment processors in Singapore as tools for founders to build a scalable ecosystem. Ecommerce and POS transactions require a payment gateway and processor, or a combination of both in an integrated platform.

In this guide, understand what differentiates a payment gateway from a payment processor in Singapore, how founders evaluate, and choose what’s best for your specific business.

What is a payment gateway

Three components are involved in a business transaction. A payment gateway acts as a data carrier between the customer’s bank, the merchant’s bank, and the payment processor. It interlinks these parties and facilitates digital and in-store purchases. As payment gateways encrypt bank information, transactions are secured with PCI DSS, and AI fraud detection.

When a customer issues a payment or clicks on a purchase payment link, payment gateways relay that information to the business account. Alongside Visa and Mastercard, payment gateways in Singapore need to support local networks like PayNow and GrabPay.

Businesses have to combine a payment gateway with a payment processor to ensure frictionless transactions.

What is a payment processor

Payment processing and authorisation controls come under payment processors. It links and facilitates the movement of funds from the customer’s bank to the merchant’s bank. Most payment processors offer a suite of services including transaction processing, flagging fraudulent attempts, chargeback controls and regulatory compliance.

When a customer swipes the card or chooses a digital payment option, payment processors verify the details and enable the transfer. Where a payment gateway initiates the transfer of information, a payment processor moves the funds.

When selecting a payment gateway in Singapore, determine the answer to these questions:

• Accepted payment methods: Does the payment gateway accept a broad and local network of payment methods, including PayNow, GrabPay, debit/credit cards, NETS, global UPIs like Apple Pay and Google Pay?
  
• Fees: How does the pricing structure compare to its competitors and are there hidden charges?
  
• Supported ecosystem: Does it fit into your pre-existing model of payment and ecommerce infrastructure? Consider and test it to avoid unnecessary expenses to reset your system.
  
• Security: What are the PCI compliant policies? Which encryption and fraud detection toolsets do they offer?

• Multicurrency transfers: If your business has a customer or vendor base cross-border, how does this payment gateway handle foreign currency and FX markups?
  

How a payment gateway and processor work together

Payment gateway and processor function as distinct units in a transaction. After the customer enters their cardholder details, a payment gateway encrypts the data and transmits it to the payment processor, which reads the data and relays it to the issuing bank. The customer’s bank runs a security test, checks the available funds, and approves or denies the transaction. The payment processor passes the bank’s verdict to the payment gateway. It then updates the business portal about the status of the transaction and a settlement occurs in the case of a successful payment.
