HoverTap™ is a board level touch and in-air gesture sensing module for OEMs and system integrators: the touch module inside the kiosks, ATMs and vending machines that kiosk manufacturers and self-service equipment manufacturers build. This article is about a cost every operator of public-facing hardware eventually runs into: what happens, and what it costs, when someone breaks the screen?
What vandalism actually costs
A cracked or smashed kiosk touchscreen or ATM touchscreen today usually means the same sequence of events: the machine goes offline, a technician has to be dispatched, and the fix is a full display module replacement, sensor, glass and all. Every hour it’s down is lost revenue on top of the service call itself, and a machine that’s visibly broken invites more damage before anyone gets to it.
The part worth noticing is that in most designs, the touch sensor and the cover glass are the same assembly. Damage one and you’ve damaged both, even if the actual impact only cracked the outer surface.
The same sequence plays out on every unattended outdoor touchscreen: ticketing and wayfinding kiosks, QSR ordering kiosks, vending machines with large displays, EV charger screens, fuel dispensers, parking pay stations and transit ticket machines. The more public and the less supervised the site, the more often it happens.
Why a bonded cover transmits the hit to the LCD
Most touch panels have their cover bonded directly to the sensor and display, in solid contact, because that’s what conventional capacitive touch (PCAP, projected capacitive) needs to keep its sensing range. The problem is that bonding transmits force as well as signal. A strike that only cracks the cover on its own can still propagate straight through to the LCD behind it, turning a cosmetic scratch into a dead panel and a full-module replacement.
The sacrificial cover and air gap design
HoverTap’s electric-field sensing doesn’t need that direct contact, which means the cover doesn’t have to be bonded to anything. An impact-rated cover, glass or polycarbonate, can sit in front of the sensor with an air gap behind it, free to absorb a hit without transmitting it to the display underneath. If the cover does eventually get damaged, it’s a sheet of polycarbonate that gets replaced, not the display module. That is what a vandal-proof or tamper proof design comes down to: the part that takes the abuse is cheap, and the part that is expensive never gets hit.
The sensing budget is up to about 13 mm of cover and air gap combined for multi-touch, and up to about 20 mm for single touch. A typical vandal proof stack is 10 mm of polycarbonate or laminated security glass with a 3 mm air gap behind it, which leaves the display mechanically separated from the cover. The thick glass article explains how far PCAP and infrared frames reach by comparison, and why.
That’s the whole argument in one line: replace the glass, not the display.
How integrators reach IK10 and IP65 behind their own cover
HoverTap itself carries UL 62368-1 at the component level. IK10 impact rating, IP65/IP67 ingress protection, and any other enclosure-level certification are the integrator’s to pursue on the finished kiosk or ATM, the same as with any other component-level display module.
Where HoverTap makes that job easier is the front of the unit: no mechanical buttons, no bezel, no seam around an IR frame to gasket. A flat, sealed, one-piece front is a much simpler thing to build an IK10 or IP65 enclosure around than a display with moving parts or exposed edges. Put simply, HoverTap lets integrators reach IK10, in IP65 and IP67 enclosures, without the touch technology dictating how thin the cover has to be.
Drop in integration for kiosk manufacturers
HoverTap is a drop in replacement for the touchscreen already in the design: HDMI in, USB HID out, plug and play, with no custom driver. It comes as a touch and in-air gesture sensor bonded to the display you already buy, or as a pre-integrated module with the sensor optically bonded to an LCD that NZTech supplies, in sizes from 7 inch to 43 inch for large format vending and digital signage. That also makes it a retrofit path: the enclosure, the PC and the software stay, and the cover gets thicker. See the HoverTap products and the kiosk and retail page for the module range.
In-air gestures are optional. The same sensor that reads a touch through the cover also reads a swipe or a twirl above it, which helps where a wet or gloved hand is easier to wave than to press.
Rain, gloves and sunlight
Outdoor kiosks and ATMs deal with weather every day, not just vandalism. Rain and condensation don’t cause false touches on HoverTap the way they can on standard capacitive touch, since sensing isn’t a simple surface-capacitance measurement that water can trigger. Heavy work and winter gloves register through the cover and air gap, so a customer in winter gloves is not asked to take them off. For sunlight readability, HoverTap modules are available with a High Bright panel option for outdoor deployments, which is what an outdoor touchscreen in direct sun needs.
Real-world proof
HoverTap Rugged is now in production for real outdoor deployments, including outdoor ATMs (the first kiosks from the current production order reach the field in 2027) and pharmaceutical vending machines (a 43″ HoverTap Rugged system enables vandalism-resistant self-service deployments at remote sites).

Sending us an evaluation request
If a kiosk or ATM design is close enough to these numbers that it matters, the fastest way to find out is to test it. NZTech’s evaluation unit programme ships a HoverTap module configured to your cover material, thickness and touch mode, so you can run it against your own enclosure for two weeks before deciding anything.
Tell us the cover material and thickness, the air gap you’re designing to, and the module size you’re targeting. We’ll configure a unit around those numbers rather than send a generic one. Evaluation units ship to OEMs and system integrators with the datasheet, mechanical drawing and STEP file; custom sizes and lead times are quoted on request.
