Ask HN: Looking to build a kiosk for event self-ticketing. Pointers?

Self-service kiosks are everywhere these days and they seem to function well. But I'm having trouble finding good options for a kiosk to use for self-service ticketing for events, to bring badges, upsell various things, etc.

Does anyone have any pointers on where to get the hardware component of the kiosks that have the built in touch display, printer, camera, etc. as well as pointers to apps that would run on them and integrate with whatever API we'd want to connect them to?
