Put a kiosk in an unsupervised public space — a transit station, a street corner, a nightlife district, a stadium concourse — and it will eventually be hit, kicked, pried and scratched. Not by most users, but once is enough. An anti vandal kiosk is not a kiosk with thicker glass; it is a system of design decisions that together determine whether an incident costs you a cleaning cloth or a field replacement. The IK rating system is the starting point of that conversation.
What IK Ratings Measure
The IK scale (from IEC 62262) rates how much impact energy an enclosure can withstand, measured in joules — roughly the energy of a known mass dropped from a known height. The scale runs from IK00 (no protection) to IK10. IK10 means the enclosure survives a 20-joule impact — approximately a 5 kg mass dropped from 40 cm. In plain terms: a deliberate strike with a heavy object, not an accidental bump.
Two things buyers should know. First, the rating applies to what was tested — usually the housing and the display window — so ask exactly which parts of the kiosk were included. Second, IK10 is about impact; it says nothing about scratches, liquids, prying or fire. Those need their own answers.

Glass: The Front Line
For the display window, IK10-level protection typically means thick tempered glass — commonly 6 mm or more — properly supported at its edges. Edge support matters as much as thickness: glass usually breaks from the edge, so the bezel design that holds it is part of the protection system, not just decoration. Laminated constructions, where glass is bonded to the touch sensor and display, add stiffness and keep fragments in place even if the worst happens.
Well-designed enclosures also treat the front glass as a replaceable, sacrificial layer: if the worst happens, a technician swaps the glass on site instead of replacing the whole display assembly. Ask how the glass is retained, what a field replacement involves and what the spare part costs — the answer changes the economics of a vandalism incident completely.
Touch Technology Choices Under Abuse
Touch technology interacts with vandal resistance in ways worth understanding:
PCAP Behind Tempered Glass
Projected capacitive touch works through the cover glass, so the entire sensing layer sits safely behind the protective surface. Even if the outer glass is scratched or damaged, the sensor itself is untouched — and the smooth, flush front gives vandals nothing to grip or pry. This is the default architecture for serious anti vandal kiosk designs.
IR Touch
Infrared touch uses a frame of emitters and receivers around the screen. It tolerates surface damage well — the display can still be used with cracked glass — but the raised frame is itself an exposed component that needs protection in public installations.
The Enclosure’s Weak Points
Ask a vandal-resistance engineer where kiosks actually fail, and they rarely point at the glass. The real weak points are:
Surface Finish and Graffiti
Powder-coated steel enclosures resist scratching and allow graffiti removal with appropriate solvents; anti-graffiti clear coats make this easier. Stainless steel offers inherent corrosion resistance for harsh coastal sites. Whatever the finish, specify it as part of the vandal-resistance discussion, not as an afterthought.
Verify, Don’t Assume
Treat anti-vandal claims like any other engineering claim: ask what was tested, to which standard, and inspect a sample unit yourself. Try the door gaps with a coin. Look at the glass edge support. Check whether the payment bezel flexes. A factory that builds IK10-level machines routinely will welcome these questions; one that buys in enclosures will struggle to answer them.
