Green mode to the max - What is an easy to use camera for the technologically challenged?

My dad still uses a disposable film camera for every trip he goes on. This is because it's simple to use. There is no focus, there is a film advance wheel and a shutter button. What camera would be the easiest for him to transition to for digital?

Ideally I imagine it having:

Green mode always (no option for aperture, shutter speed, iso - it's all auto)

Very simple - easy to see and use controls to view photos and delete photos.

Minimal buttons - on/off, view photo controls, shutter and zoom are all that's needed for him.

Thanks for your help!
