I did about ten years back for a client. Android-based tablets, peripherals connected via USB HID, front end built on libGDX (it was a gaming-related product), in-house remote management agent + back end (a WebSocket key/value store + pubsub db managed with a Django app, SSH + adb for fallback device access). Overall I was happy with the approach but if I were building it today hopefully there would be better off the shelf software for the back end. The client's business involved renting the kiosks to customers of their larger gaming business.
