Linux May Succeed Windows XP As OS of Choice For ATMs 367
Dega704 sends this news from ComputerWorld:
"Some financial services companies are looking to migrate their ATM fleets from Windows to Linux in a bid to have better control over hardware and software upgrade cycles. Pushing them in that direction apparently is Microsoft's decision to end support for Windows XP on April 8, said David Tente, executive director, USA, of the ATM Industry Association. 'There is some heartburn in the industry' over Microsoft's end-of-support decision, Tente said. ATM operators would like to be able to synchronize their hardware and software upgrade cycles. But that's hard to do with Microsoft dictating the software upgrade timetable. As a result, 'some are looking at the possibility of using a non-Microsoft operating system to synch up their hardware and software upgrades,' Tente said."

I've seen XP on some ATMs, not XPe, although it does get annoying when an ATM is down due to an XP activation screen.
The ATM industry needs to stop being pennywise and pound foolish.
Instead, they need to design their platform once, do it right, then as time goes on, add a UI refresh every so often so the cute cartoon characters get a facelift every year or two.
Were it up to me with ATM design, I'd probably charge off a quarter profit to do the architecture right, then once done, pretty much coast from there.
First, I'd give a lot of consideration to QNX. ATMs are not really needing a RTOS, but QNX has an excellent reputation for security (with decent government certifications to back that.) From there, add a TPM chip, userland, and the application. Done right, someone plugging in an unauthorized USB flash drive won't be able to do as much, compared to XP with AutoPlay/AutoRun turned on.
Linux is also a good choice. One could go with a full userland or an Android style userland, both with SELinux to minimize damage. Linux may not have the C2 cert that QNX does, but it will hold its own in security, if done right.

This can be hard in practice. Vendors of niche products often only support Windows. Even if they support other OSes, you end up being the beta tester since the code is not as widely used. We ended up using XP embedded years ago because, of all things, USB memory stick compatibility. We tried to use Wind River's drivers, Linux drivers (years ago), and even Windows CE - but XP was the only solution that worked with almost every stick out there. When we used Wind River's solution, we had to maintain a compatibility list. But this effort was impossible once they started to explode in popularity. We of course sold compatible sticks to use with our equipment, but this was not popular with our customers and our competitors used Windows, so we were at a disadvantage.

I suspect ATMs straddle the line between being too sophisticated and varied to lend themselves to a simplistic embedded system, and too niche a product to be cost effective to develop a specialized OS from the ground up.

Now that Linux has gone mainstream it does open the door to a specialized OS since it need not be built from the ground up - adding and removing modules typically involves *far* less effort, especially when there are numerous variations of stripped-down specialty distros to start from.

The ATM hardware basically is static, but the software it runs on is customized for the bank and for the purpose the bank is using it for.
Embedded OS tools generally are quite awful and hard to set up. But desktop tools are easier to use - just point a developer at Visual Studio, the source repo and they can get building that afternoon. And with a few peripherals, they can even emulate the ATM hardware right on their desktop without having to have the ATM beside them, transfer the code and assets over, etc.
Anyhow, it's not like banks didn't have a lot of notice - way back in the Windows 7 days Microsoft had already announced end of support (this was over 5 years ago). They reiterated it several times since then. The fact that support was ending next month has been known for years.
Problem is, most companies see it as "far off" and too far away to bother, ignoring the fact that migrating can take years. Just because you were told in 2009 that XP was going away in April 2014, means most companies will ignore it until the last minute.

Now, ATM venders are faced with having to port everything to newer versions of Windows, which forces them into more expensive hardware (faster CPU's, more memory, greater drive space, modern video hardware etc.).
