The history of ATMs and kiosks

The history of these machines traces back to the late 1960s for the ATM, which revolutionized personal finance, while the Self-kiosk Machine emerged later in the late 1970s as an educational and retail tool, eventually evolving into the high-speed transactional terminals we see today.

The ATM was born out of a specific need to provide banking services outside of traditional bank hours. The first ATM was installed in London in 1967, focusing strictly on cash dispensing. This early financial Self-kiosk Machine was a marvel of mechanical engineering, eventually transitioning to digital networks in the 1970s and 80s. During this time, the ATM established the standard for secure, automated transactions. It proved that customers were willing to interact with a machine for sensitive tasks, paving the way for the broader Self-kiosk Machine market that would follow in subsequent decades.

In contrast, the Self-kiosk Machine had more diverse beginnings. The first recognizable interactive kiosk was developed in 1977 at the University of Illinois at Urbana-Champaign. Known as the PLATO Hotline, it was an informational Self-kiosk Machine that allowed users to find campus information. Throughout the 1980s and 90s, the Self-kiosk Machine concept expanded into retail and photo printing. Unlike the ATM, which remained focused on the banking sector, the Self-kiosk Machine became a "chameleon" of technology, adapting its hardware and software to fit the needs of airports, museums, and fast-food restaurants.

Today, both machines have converged in terms of modern aesthetics and touch-screen interfaces, yet their paths remain distinct. The modern Self-kiosk Machine has benefited from the massive leap in cloud computing and IoT connectivity, allowing it to become a central hub for omnichannel retail. Meanwhile, the ATM has evolved into the "Advanced Function ATM," which mimics some traits of a Self-kiosk Machine by allowing for bill payments and card dispensing. Despite this overlap, the historical identity of the ATM as a "cash vault" and the Self-kiosk Machine as a "service portal" continues to define their engineering and deployment strategies in 2026.

Similarities

Both the ATM and the Self-kiosk Machine share the core objective of providing 24/7 autonomous service to users, utilizing similar hardware components like touchscreens, processors, and network connectivity to reduce human labor requirements.

At their most fundamental level, an ATM and a Self-kiosk Machine are both "unattended terminals." They are designed to stand in public or semi-public spaces and function without a human operator present. Both types of hardware rely on an internal PC or industrial motherboard to run specialized software. When a user approaches a Self-kiosk Machine or an ATM, they are greeted by a Graphical User Interface (GUI) that guides them through a series of prompts. This shared reliance on intuitive UI design is what makes both the ATM and the Self-kiosk Machine accessible to the general public regardless of their technical skill level.

From a hardware standpoint, there is significant overlap in the peripherals used. Both machines often feature thermal printers to provide receipts, encrypted touch-pads for data entry, and card readers (though the ATM's reader is usually more specialized for banking security). Furthermore, the modern Self-kiosk Machine and the ATM both require robust network connections—whether through hardwired Ethernet, WiFi, or 4G/5G cellular modems—to communicate with central servers for transaction authorization. This connectivity allows both the ATM and the Self-kiosk Machine to provide real-time updates to the business owner regarding inventory levels or mechanical health.

In the B2B sector, the business model for both machines is also similar. They are viewed as "efficiency multipliers." By installing a Self-kiosk Machine, a retailer can handle more customers during peak hours without hiring more staff; similarly, a bank uses ATMs to reduce the number of tellers needed for simple transactions. Both the ATM and the Self-kiosk Machine provide valuable data analytics, tracking user behavior and transaction volumes to help managers make informed decisions. Whether it is a financial Self-kiosk Machine (ATM) or a retail Self-kiosk Machine, the goal is to drive down the cost-per-transaction while increasing customer convenience.

Different purposes

The purpose of an ATM is strictly defined by financial liquidity, whereas a Self-kiosk Machine serves a broad spectrum of non-financial or service-specific functions, making the Self-kiosk Machine a more versatile tool for general business operations.

The ATM is the king of "Cash In, Cash Out." Its purpose is to act as a bridge between a digital bank account and physical currency. Because of this, every component of an ATM is built around the secure storage and dispensing of banknotes. You will rarely see an ATM used to buy a movie ticket or check in for a flight; its software is locked into a specific banking protocol. For a B2B operator, an ATM is a service provided to ensure customers have access to cash, which can then be spent within the establishment. It is a specialized financial Self-kiosk Machine that handles the most sensitive type of "physical data"—money.

On the other hand, the Self-kiosk Machine is a "solution-specific" terminal. Its purpose changes depending on the software loaded onto it. In a restaurant, the Self-kiosk Machine is a digital waiter that handles menu navigation and upselling. In an airport, the Self-kiosk Machine is a check-in agent that verifies passports and prints luggage tags. Because the Self-kiosk Machine does not usually have to store thousands of dollars in cash, its enclosure can be much thinner and more aesthetically diverse. The Self-kiosk Machine is designed to facilitate a "workflow" rather than just a "payout."

Furthermore, the Self-kiosk Machine is increasingly used for "Automated Retail." This is where the Self-kiosk Machine acts as a high-end vending machine for electronics, cosmetics, or even hot food. While an ATM only "sells" cash, the Self-kiosk Machine can sell a physical product, a digital service, or simply provide information. This diversity of purpose is why the Self-kiosk Machine market is growing at a faster rate than the traditional ATM market. For any business looking to automate a complex task, the Self-kiosk Machine is the hardware of choice, whereas the ATM remains the specialized tool of the financial world.

Functional Comparison Matrix

Security

Security for an ATM is primarily focused on physical hardening and anti-fraud measures for cash, while Self-kiosk Machine security prioritizes data privacy, software "lockdown," and the prevention of digital tampering.

When we talk about ATM security, we are talking about steel and alarms. An ATM must be able to withstand physical attacks, such as "ram-raiding" or "explosive" attempts to access the safe. It is a financial Self-kiosk Machine that must also guard against "skimming"—the placement of illegal devices over the card reader to steal data. Because an ATM holds physical assets, its security is a matter of both digital encryption and heavy-duty physical engineering. B2B owners who install ATMs must often consider floor-loading requirements and specialized insurance because of these physical risks.

In contrast, the security of a Self-kiosk Machine is largely centered on the integrity of the software. Since most Self-kiosk Machine units do not hold significant amounts of cash, they are less likely to be physically attacked for their contents. Instead, the risk is "cyber-tampering." A Self-kiosk Machine must be running a "Kiosk Mode" software that prevents users from accessing the underlying Windows or Android operating system. If a Self-kiosk Machine is not properly secured, a hacker could potentially use the touchscreen to browse the web, install malware, or access the restaurant's internal network.

However, both the ATM and the Self-kiosk Machine must comply with Payment Card Industry (PCI) standards if they process credit card transactions. For a Self-kiosk Machine, this means using "Point-to-Point Encryption" (P2PE) so that credit card data is never stored in the machine's memory. While the ATM is a "fortress" for cash, the Self-kiosk Machine is a "vault" for data. As we move deeper into 2026, both machines are incorporating more biometric security, such as facial recognition or palm-vein scanning, to ensure that the person using the Self-kiosk Machine or ATM is who they say they are. This evolution in security continues to make self-service technology the safest way to conduct business.

Critical Security Layers for Self-kiosk Machine

• Kiosk Lockdown Software: Prevents unauthorized OS access.

• Encrypted Card Readers: Protects financial data at the point of entry.

• Tamper-Evident Seals: Alerts staff if the Self-kiosk Machine enclosure has been opened.

• Privacy Filters: Prevents "shoulder surfing" in busy public areas.

• Remote Monitoring: Allows for instant shutdown of the Self-kiosk Machine if a breach is detected.

Conclusion

The distinction between ATMs and kiosks is a perfect example of how specialized technology evolves to solve specific problems. While the ATM remains the unrivaled champion of automated personal finance and cash management, the Self-kiosk Machine has become the versatile workhorse of the modern service economy. For B2B stakeholders, the choice between these two is not about which is "better," but which serves the specific needs of the customer journey. The ATM provides liquidity, while the Self-kiosk Machine provides a streamlined, interactive service experience.

As we have explored, the history, similarities, and divergences in purpose and security define these two categories. Industry platforms like the ATM Marketplace and BuyerZone emphasize that while the hardware may look similar, the operational "soul" of an ATM is different from a Self-kiosk Machine. One is a high-security financial tool, and the other is a flexible digital interface. For a restaurant or retail store, the Self-kiosk Machine is the key to unlocking higher throughput and better customer data, while the ATM is a value-added service that keeps the "cash flow" moving—literally.

In conclusion, the Self-kiosk Machine is the future of interactive service, offering a platform that can grow and change with your business. Whether you are looking to automate your check-in process, improve your order accuracy, or provide an informational hub, the Self-kiosk Machine is the hardware of choice.
