Today’s society is highly regarded as a fast-moving one, and as a result, self-service terminals are essential in many fields. Whether you are using an automated teller machine, a ticketing machine, or a checking-in machine at a hospital and so on, all your needs are served by these machines through the integration of a very important device known as the embedded PC. In this article, I will guide you on how to get started correctly with embedded PCs in self-service terminals and examine a variety of self-service terminal solutions to help you improve operations, enhance efficiency, and minimize errors to get users the help they need as soon as possible. 

Self-service terminals refer to automated machines or devices that allow customers to perform tasks independently without requiring assistance from staff. 

Main Components of Self-Service Terminals

Self-service terminals are comprised of various essential components. They are mainly included:

- Embedded PC: The brain of the self-service terminal, controlling all functions and operations.

- Touchscreens or Keypads: Providing an interface for users to interact with the machine.

- Card Readers & Scanners: Required for any payment or identification checks.

- Connectivity Modules: Ensure the terminal can communicate with other systems, whether through the internet, Wi-Fi, or mobile networks.

Common Applications of Self-Service Terminals

Self-service terminals are applied in many industries, including:

- Retail: Automated checkouts opted in supermarkets.

- Smart Cities: Information kiosks and parking payment stations.

- Quick Service Restaurants (QSR): Ordering kiosks.

- Banks: ATM and VTM machines for cash withdrawals and deposits.

- Public Transit: Ticket vending machines, traffic light monitoring.

- Hospitals: Patient check-in terminals.

These different applications demonstrate how the powerful self-service terminals are driven by the embedded PCs for efficient and automated service.

An embedded PC is the core part of any self-service terminal equipment, and it needs to satisfy several technical demands as follows:  

1. High Performance and Efficiency: These systems have to accommodate multiple tasks at once – starting with data processing and ending with fast transactions. Such functionality, of course, puts high demands on the performance of the embedded PCs in question.

2. Robust Durability and Reliability: Outdoor self-service terminals may be deployed at locations that could expose them to very low temperatures, dust, and humidity, like gas stations, highway toll station systems, remote meter readings and water purification. These conditions are ideal for embedded PCs to survive so the terminal will remain functional.

3. Compact Design: Due to the restrictions inherent in self-service terminals, embedded PCs must have a compact but powerful design to maintain computing capability.

4. Connectivity and Integration: The purpose of its communication capabilities is to be able to integrate with other external systems, including payment gateways, cloud service, etc., through network connectivity options, including Ethernet, Wi-Fi, or 4G/5G.

5. Security Features: Some examples include the banking fields or health institutions. The information processed is often confidential. The embedded PCs used in the self-service terminals need to be secure enough not to allow unauthorized access to the data.
