Complete Guide to EFTPOS for Australian Businesses

EFTPOS (Electronic Funds Transfer at Point of Sale) is a payment system that allows businesses to accept electronic payments in person using a card, smartphone, or digital wallet. It connects the customer, their bank, and the business to process transactions and transfer funds electronically at the point of sale.

EFTPOS is used by businesses across Australia every day, but many merchants don’t fully understand what happens behind the scenes when a customer taps, inserts, or swipes their card. Understanding how EFTPOS works helps businesses make better decisions about costs, setup, and customer experience.

In this guide, we’ll explain what EFTPOS means, how transactions work, the benefits and disadvantages for businesses, and what to look for when choosing a provider ^*.

EFTPOS is an electronic payment system that enables businesses to accept card and contactless payments at the point of sale.

It connects:

• The customer’s bank account,

• The merchant’s business account, and

• A payment network (such as eftpos, Visa, or Mastercard)

When a payment is made, funds are transferred electronically between accounts, removing the need for cash and enabling fast, secure transactions.

In simple terms, EFTPOS:

• Transfers money electronically between accounts.

• Is used for in-person and mobile payments.

• Works via cards and digital wallets like Apple Pay and Google Pay.

EFTPOS stands for Electronic Funds Transfer at Point of Sale.

It describes the process of transferring funds electronically from a customer’s bank account to a business during a transaction.

Australia has seen a major shift away from cash, with customers expecting fast, seamless payment experiences.

EFTPOS can support:

• Faster checkout times in retail.

• Efficient service during peak periods in hospitality.

• Flexible payment options for mobile and service-based businesses.

For most businesses, EFTPOS is now a core part of day-to-day operations, not just a convenience.

EFTPOS transaction are typically processed in seconds, but several steps take place behind the scenes:

1. Customer initiates payment
   The customer taps, inserts, or swipes their card (or uses a mobile wallet).
2. Terminal captures payment details
   The EFTPOS machine reads the card or device information.
3. Data is encrypted
   Payment details are securely encrypted before being sent.
4. Transaction sent to payment network
   The request is routed via eftpos, Visa, Mastercard or American Express networks.
5. Issuing bank approves or declines
   The customer’s bank checks for sufficient funds and authorises the payment.
6. Response returned to terminal
   Approval or decline is displayed within seconds.
7. Funds are settled to the merchant’s account
   The payment is transferred to the business account, typically within 1–2 business days depending on your selected bank.

Several key players are involved:

• Issuing bank – the customer’s bank.

• Acquiring bank/provider – the merchant’s payment provider.

• Payment networks – EFTPOS, Visa, Mastercard or American Express.

These systems communicate in real time to validate, approve, and complete transactions securely.

EFTPOS supports a range of payment methods, giving customers flexibility while helping businesses accept payments seamlessly.

A debit card is linked directly to a customer’s bank account.

• Payments are taken from available funds.

• Transactions are typically processed in seconds.

• Common for everyday purchases.

A credit card allows customers to borrow money from a financial institution to make purchases.

• Payments are billed later.

• May include interest or fees for the customer.

• Often used for larger or planned purchases.

The key differences between debit and credit card payments include:

• Source of funds:
  Debit = bank account | Credit = borrowed funds.

• Fees for businesses:
  According to the Reserve Bank of Australia (RBA), Debit card transactions often have lower merchant fees than credit card transactions ^{^}.

Contactless payments allow customers to simply tap their card or device on the terminal.

This includes:

• Physical cards

• Apple Pay.

• Google Pay.

• Samsung Pay.

Benefits may include:

• Faster transactions.

• Reduced queues.

• Improved hygiene and convenience.

For businesses evaluating payment systems, it’s important to weigh both the benefits and limitations.

EFTPOS offers several practical advantages:

• Faster transactions
  Can help speed up checkout and improves customer flow.

• Improved customer experience
  Supports preferred payment methods like contactless.

• Reduced cash handling
  Can help reduce the risk of theft and human error.

• Better reporting and tracking
  Digital records make reconciliation easier.

There are also considerations to be aware of:

• Transaction fees
  Costs vary depending on provider and card type.

• Hardware and setup costs
  Terminals and integration may require upfront investment.

• Reliance on connectivity
  Requires internet or network access to process payments.

• Settlement delays
  Funds are not always received instantly.

An EFTPOS machine is the physical device used to process card payments.

It:

• Reads cards or digital wallets

• Connects to payment networks

• Processes transactions securely

These machines are essential for accepting in-person payments and are commonly found at checkout counters, tables, or on the go.

Different business types require different setups:

• Countertop terminals
  Fixed devices used in retail environments.

• Portable terminals
  Ideal for hospitality and table service.

• Mobile EFTPOS machines
  Designed for trades, events, and on-the-go businesses.

A common misconception is that EFTPOS and POS are the same, but they serve different roles.

In simple terms:

EFTPOS is responsible for taking payments, while a POS system manages the entire sales and business process.

When integrated with a POS system, the payment amount is automatically sent from the POS directly to the terminal, removing the need for manual entry. This can create a more seamless checkout experience, which can help speed up transactions, reduce manual entry errors, and improve reporting accuracy.

EFTPOS comes with several cost considerations that can vary depending on the provider and setup. These typically include transaction fees charged per payment, merchant service fees for processing card payments, and any terminal or hardware costs required to accept payments. Understanding how these costs are structured is important when comparing providers and choosing the right solution for your business.

Costs can vary depending on:

• Transaction volume.

• Card type (debit vs credit).

• Pricing model of the provider.

• Industry and business size.

Understanding these variables can help businesses choose a solution that aligns with their needs.

Security is a core component of EFTPOS systems. Businesses handle sensitive payment data, so strong protections are an important consideration.

EFTPOS systems use multiple layers of security to protect sensitive payment information. This includes encryption to secure data during transmission, the use of trusted payment networks to process transactions safely, and the avoidance of storing sensitive card details on the terminal. Payment providers that handle cardholder data may also be subject to security standards such as PCI DSS, which set requirements for protecting payment account data.

Once you understand how EFTPOS works, the next step is choosing the right provider.

Key considerations include:

• Transparent pricing and fees.

• Reliability and uptime.

• Integration with your POS system.

• Customer support and local expertise.

• Flexibility for your business type.

The right provider should support your day-to-day operations while helping your business grow.

EFTPOS plays a central role in modern commerce, enabling businesses to accept fast, secure electronic payments.

By understanding:

• What EFTPOS is

• How transactions work

• The benefits and potential limitations

…businesses can make more informed decisions about their payment systems.

As customer expectations continue to evolve, choosing the right EFTPOS solution isn’t just about processing payments, it’s about supporting long-term growth and delivering better customer experiences.

Choosing the right EFTPOS solution can make a big difference to how your business operates day to day. Whether you’re setting up for the first time or looking to switch providers, it’s worth finding a solution that fits your needs  ^§.
