What Is EFTPOS?

EFTPOS is a system that allows money to be transferred directly from a customer’s bank account to a business at the time of purchase. It is used at the point where the sale happens.

Customers can pay using:

  • Debit cards
  • A credit card
  • Mobile wallets such as Apple Pay


The process happens through a connected network that links banks and payment devices.

What Does EFTPOS Stand For?

EFTPOS stands for Electronic Funds Transfer at Point of Sale. The name describes how the system works.

  • Electronic transfer means the payment is handled digitally
  • Point of sale refers to where the transaction takes place


This allows businesses to accept payments without handling physical cash.

How Does EFTPOS Work?

When a purchase is made, the system processes the payment quickly through a secure network.

The process usually involves:

  • A customer taps, swipes, or inserts their card into a terminal
  • The system checks if funds are available
  • The payment is approved or declined
  • The transaction is completed instantly


In some cases, customers may need to enter a PIN for security.

Types of EFTPOS Payments

There are several ways customers can complete transactions using this system.

  • Card Payments - Customers insert or swipe their card and confirm the payment, often with a PIN.
  • Contactless Payments - With contactless payment, users simply tap their card or device to complete the transaction quickly.
  • Mobile Wallets - Digital wallets such as Apple Pay allow payments using smartphones or wearable devices.

EFTPOS Machines and Terminals

An EFTPOS terminal is the device used to process transactions. These devices are commonly found in retail stores, restaurants, and service businesses.

Modern terminals often include:

  • Touchscreen displays
  • Wireless connectivity
  • Integration with other business tools


They are designed to make payments quick and easy for both customers and staff.

EFTPOS and POS Systems

EFTPOS is often part of larger pos systems used by businesses. These systems manage sales, transactions, and records.

A point of sale (POS) setup can:

  • Record transactions automatically

This integration helps businesses manage operations more effectively.
