POS Terminals & In-Store Payments: A Buyer’s Guide for Southeast Asian Merchants

The Role of POS Terminals in Modern Commerce

For many businesses, digital transformation starts online. However, the physical checkout experience remains one of the most important customer touchpoints. Whether you operate a retail store, restaurant, hotel, clinic or service business, your ability to accept payments quickly and securely can directly influence customer satisfaction and sales.

This is where a POS terminal becomes essential.

A POS (Point of Sale) terminal allows businesses to accept card payments, contactless transactions, mobile wallets and other digital payment methods at physical locations. In markets across Southeast Asia, these devices are commonly referred to as EDC machines, card terminals, card machines, mesin EDC (Indonesia) or máy POS (Vietnam). In Indonesia, some smaller merchants also use the term mesin kasir loosely to describe their till and card-payment set-up, though it technically refers to the cash register rather than the card device itself.

As consumer preferences continue shifting towards cashless payments, choosing the right POS terminal has become a strategic business decision rather than simply an operational necessity.

What Is a POS Terminal?

A POS terminal is a payment acceptance device that enables merchants to process transactions in-store.

Modern POS terminals can accept:

• Credit cards
• Debit cards
• Contactless card payments
• Mobile wallets
• QR code payments
• Alternative payment methods

Unlike traditional cash registers, today’s POS terminals are often connected to broader payment ecosystems, allowing businesses to consolidate reporting, manage multiple payment channels and support omnichannel customer journeys.

Why POS Terminals Matter 

Customer expectations have changed significantly over the past decade.

Many shoppers now move seamlessly between online and offline channels. They may discover products online, visit a physical store to complete the purchase, and expect the same payment convenience throughout their journey.

Businesses that offer flexible payment options often benefit from:

• Faster checkout experiences
• Reduced cash handling
• Improved customer satisfaction
• Greater payment choice
• Better transaction visibility
• Enhanced operational efficiency

For growing merchants, the right POS setup can also help bridge online and offline sales channels, creating a more unified commerce experience.

Types of POS Terminals Available Today

Traditional Countertop POS Terminals

These are fixed payment devices typically found at checkout counters.

Best suited for:

• Retail stores
• Supermarkets
• Pharmacies
• Service centres

They offer stable connectivity and are often integrated directly with cashier systems.

Portable Wireless Card Terminals

Portable terminals use Wi-Fi or mobile connectivity, allowing staff to accept payments anywhere within a store.

Best suited for:

• Restaurants
• Cafés
• Hospitality businesses
• Events

These devices improve customer convenience by bringing payment acceptance directly to the customer.

Mobile POS (mPOS)

Mobile POS solutions turn smartphones or tablets into payment acceptance devices.

Merchants can use compact card readers or tap-to-pay functionality on compatible devices to accept payments without investing in extensive hardware.

Best suited for:

• Small businesses
• Pop-up stores
• Delivery services
• Field sales teams

SoftPOS: Accept Contactless Payments on a Smartphone

SoftPOS (software point of sale) solutions allow merchants to accept contactless payments directly on a compatible NFC-enabled smartphone or other supported device, without requiring a separate card terminal. Instead of relying on dedicated payment hardware, the device uses software to facilitate contactless payment acceptance, subject to the solution’s device, security and payment channel integration requirements.

Unlike traditional POS terminals, which use dedicated payment hardware, or mPOS setups that may require a separate card reader, softPOS can offer a more streamlined way to accept contactless payments with fewer hardware requirements.

SoftPOS may be suitable for:

• Small and growing businesses seeking a more flexible payment setup
• Retail staff who need to accept payments across a store
• Delivery and field teams accepting contactless payments on the go
• Businesses looking to reduce reliance on dedicated payment terminals

When evaluating softPOS, merchants should check supported devices, accepted payment methods, security requirements and integration options to ensure the solution meets their business needs.

Integrated POS Systems

These combine payment acceptance with inventory management, sales reporting and customer management features.

Integrated solutions are popular among merchants seeking a unified operational platform rather than standalone payment devices.

Key Features to Look For When Choosing a POS Terminal

1. Payment Method Acceptance

The first consideration should be payment flexibility.

Your POS terminal should support:

• Visa and Mastercard
• Local debit networks
• Contactless payments
• Mobile wallets
• QR payments
• Alternative payment methods

Southeast Asia is one of the world’s most diverse payments markets. Supporting local customer preferences can help reduce checkout friction and improve conversion rates.

2. Omnichannel Capability

Today’s merchants increasingly operate across multiple channels.

A customer may:

• Browse online
• Purchase in-store
• Return via another channel
• Redeem loyalty rewards across platforms

Choosing a POS solution that integrates with your online payment infrastructure can help create a more seamless customer experience.

3. Security and Compliance

Payment security should never be overlooked.

Look for providers that comply with industry security standards and work with recognised card schemes. Security features help protect both merchants and customers while reducing operational risk.

4. Reporting and Reconciliation

Managing multiple payment channels can become complex.

A modern POS solution should provide:

• Transaction reporting
• Settlement visibility
• Centralised dashboards
• Simplified reconciliation

Consolidated reporting becomes particularly valuable for businesses operating across multiple locations.

5. Connectivity and Reliability

Payment interruptions can directly impact revenue.

Evaluate:

• Wi-Fi connectivity
• Mobile network support
• Offline capabilities where available
• Device reliability

For high-volume merchants, uptime is critical.

POS Terminal vs EDC Machine: Is There a Difference?

In many Southeast Asian markets, the terms are used interchangeably.

EDC stands for Electronic Data Capture, a term widely used by banks and payment providers across Indonesia, Malaysia and several neighbouring markets.

Generally:

• POS terminal = broader industry term
• EDC machine = payment acceptance device used for card transactions

Both refer to hardware that enables electronic payment acceptance at the point of sale.

Businesses researching mesin EDC, card terminals or card machines are often evaluating similar categories of payment acceptance technology.

Considerations for Multi-Market Businesses in Southeast Asia

Merchants expanding across Southeast Asia face additional challenges.

The region’s digital economy is projected to pass US$300 billion in gross merchandise value in 2025, according to the e-Conomy SEA 2025 report by Google, Temasek and Bain & Company, and independent research from the Visa Consumer Payment Attitudes Study confirms that cashless habits are now firmly embedded across the region’s major markets.

Each market has unique payment preferences:

• Indonesia has strong demand for local payment methods and extensive EDC machine usage.
• Vietnam continues to see growing adoption of card and digital payments through POS infrastructure.
• Malaysia combines card payments, QR payments and mobile wallets.
• The Philippines has experienced rapid growth in digital payment adoption.
• Thailand has become increasingly cashless across both retail and hospitality sectors.

For regional merchants, selecting a provider with broad payment coverage can reduce the complexity of managing separate integrations and vendor relationships across multiple countries. 2C2P supports more than 400 payment methods across Asia, helping businesses scale across diverse markets through a single payments ecosystem.

Questions to Ask Before Selecting a POS Provider

Before committing to a solution, consider asking:

• Which payment methods are supported?
• Can the terminal integrate with existing POS software?
• What are the settlement timelines?
• How are refunds handled?
• What reporting tools are available?
• Does the provider support multiple markets?
• What customer support is available?
• Can the solution support future omnichannel expansion?

The answers can significantly affect long-term operational efficiency and scalability.

Choosing a POS Terminal That Supports Growth

A POS terminal is no longer just a device for accepting card payments.

For modern merchants, it serves as a critical connection point between customers, payment methods and business operations. The right solution should not only process transactions securely but also support omnichannel commerce, simplify reconciliation and provide the flexibility needed to grow across Southeast Asia.

As customer expectations continue evolving, businesses that invest in scalable and integrated payment infrastructure will be better positioned to deliver seamless experiences across every touchpoint.
