    Depends on which part? Tldr; mostly no.
    The user facing software can do everything including control all the exotic hardware components like the dispenser module and knows how to talk to the atm or bank network to do transactions. That thing is closed.
    The operating system can vary from linux based to windows based. I’ve seen machines which boot into the desktop and just start the app. If you had a keyboard, you could alt tab back to the desktop lol. They’re often made in Java.
    The drivers and control software for the mechanical components (dispenser, card reader…) are also proprietary. There’s a specification for how communication between software and these devices is done, called WS/XFS. Not open source, but you can get it and read it to understand better how the software communicates with the hardware.

    Generally, the term “open source” refers to software. Are you asking about the software that controls ATMs, or the physical machine?

    Either way, the answer is probably no, but the reason will differ depending on what your question is.

    I think there’re a few crypto based ones out there from when people were trying to make bitcoin in shops a thing, no idea if they’re even still maintained.

    If you’re talking about a traditional ATM that hooks into a specific bank or interbank network, you’re not going to find a complete system, because the banks basically only want machines they (or partnered banks) own talking to their systems.

    Depending what you’re interested in though, Linux based OSes (standard enterprise RHEL and the like) seem to be becoming increasingly used, but there’s still probably a big majority running some form of windows (or funnily enough OS/2). And a quick Google has shown me the industry has seemingly actually worked out an SDK for talking to the ATM hardware that’s catching on, XFS4IoT. However the software written by the bank to implement that SDK and actually talk to the banking network is (and basically always will be) proprietary software.

        Yeah if it’s not owned by a bank, it will be owned by an institution that runs (or otherwise has access to) a proprietary interbank network. In most countries consumer financial services are super regulated legally, so everything gets locked down

          It’s not the regulations, it’s the banks. They’re super paranoid, everything has to be proprietary. And at the same time their backends are all ancient and seriously decrepit. Which has to be kept secret and airgapped from the public.
