What Is an Interactive Kiosk?

An interactive kiosk is a self-service computer terminal built for the public. A touchscreen shows the application, a computer inside the enclosure runs it, and peripherals such as a payment terminal, receipt printer or barcode scanner complete the transaction, all without a member of staff. The first one was built in 1977 at the University of Illinois to show students directories and bus timetables, and kiosks now handle everything from burger orders to hospital check-ins.

Behind the glass, every kiosk follows the same pattern. The customer touches the screen, the application talks to a back-office system over the network, and the peripherals take payment, print a ticket or read a barcode. The software runs in a locked-down kiosk mode so that users cannot reach the desktop, and the whole system is managed remotely because nobody sits beside it.

Kiosks are usually named after the job they do. The job decides the screen size, the peripherals and how robust the enclosure must be.

A kiosk is specified from the screen outwards. The display and computer are usually chosen as one part, because the enclosure is built around them.

The most common build is an open frame panel PC: the touch display and the computer in one chassis with rear-mount brackets, so it bolts into the kiosk from behind. Our open frame panel PCs cover this from small information points to large ordering screens. Where the computer has to sit elsewhere in the cabinet, a separate open frame or PCAP touch monitor is driven by a fanless mini PC.

Touch is almost always projected capacitive (PCAP), which senses through toughened cover glass and handles multi-touch gestures. Resistive touch still suits gloved or wet hands, and infrared suits very large screens. Our guide to choosing touch technology for industrial displays compares the options. The computer then needs the right ports for the peripherals: several USB and serial ports for the printer, scanner and payment terminal, a second display output for a customer-facing screen, and a watchdog and auto power-on so it recovers from a power cut without a visit.

The biggest split in kiosk hardware is whether the sun and the weather reach the screen.

For forecourts, station platforms and kerbside points, sunlight readable monitors with optical bonding keep the screen legible in direct sun and stop condensation forming behind the glass. Our FAQ on the IK rating for impact resistance explains the impact grades.

One kiosk is a project; a hundred is an estate that has to be kept running with nobody on site. Lock the operating system with a kiosk mode such as Windows assigned access, so the application relaunches if it closes. Monitor every kiosk centrally, push updates out of hours and use remote management to restart or reimage a stuck kiosk. Keep the build under revision control, so the hundredth kiosk uses the same computer, image and touch firmware as the first.

Accessibility is now a legal point as well as a design one. In the EU, the European Accessibility Act has applied to new self-service terminals such as ticketing and check-in machines since June 2025, and in the US the ADA sets reach ranges for operable parts. Our retail and self-service kiosk page shows how displays, computers and edge AI fit together across a store or estate.

We supply open frame panel PCs and fanless computers to kiosk builders with the I/O, mounting and a locked-down operating system image fitted and tested before they ship as standard, and match touch monitors to the enclosure glass. Send us the enclosure, the peripherals and the site, and we will specify the display and computer to suit.
