A small footprint matters. Large enterprise hardware is almost never top-spec, and the last thing you need is another background service eating memory. Duo Input is built to be invisible.

Patent and IP

## Patented. Protected for us and for you.

Duo Input is patent-protected technology. Simultaneous multi-display input isn't something we stumbled into; it's something we solved, filed, and defended. For customers, that means two things: the capability is durable, and the investment you make building workflows on top of it isn't going to be commoditized out from under you.

FAQ

Does Duo Input require changes to my POS or line-of-business software?

No. Duo Input sits between your displays and your application. Most customers deploy it without touching their POS at all.

Does it work with any touch monitor?

Yes. Any standard touch display supported by Windows or Linux. No proprietary hardware required, though ID24's D|2 displays are purpose-built for this class of deployment.

Does it need an internet connection?

No. Duo Input runs entirely on-device. That matters for compliance, for latency, and for the times when the store network drops.

Can we scale this across hundreds of locations?

Yes. Duo Input is deployed today across multi-site retail networks and supported by ID24's rollout methodology. Central licensing, remote install and standard imaging are all handled.

How is this different from just using two separate computers?

Two computers means two sessions, two sets of state, and two places to keep in sync. Duo Input gives you one application, one transaction, and two live input streams. The workflow stays whole.

Is there a developer SDK?

Yes. Get in touch and we'll route you to the right technical contact.
