Windows ATMs by 2005
An anonymous reader writes "O'Reilly Developer News is running a brief on how the banking industry will be running a stripped down version of windows on 65% of its ATM machines by 2005. On a morning when I'm receiving the latest windows virus in my inbox every five minutes I feel very comfortable with this."
Fortunately for the banking industry and unfortunately for you, most ATMs have built-in failsafes to keep that from happening.
If you completely disregard that most ATMs don't have built-in TCP/IP stacks-- even the ones that communicate via CDPD, or cellular to internet use a transmitter that works through a serial port and sends an encrypted stream of data to the processor-- Most ATMs are designed to go balls-up at the first sign of trouble and shut themselves down after sending detailed error messages to their owners via leased lines. Out of paper? Error message, shut down. Out of money? Error message, shut down. OS Crash? Error message, shut down. Damage to the ATM Case? Error message, shut down.
The next Slashdot story will be ready soon, but subscribers can beat the rush and slashdot the links early!
As someone who has used and stood in line to use one of these machines, let me just say that they are a far cry from the efficiency of the current ATMs. Just on a rough estimate, it takes 3-4 times longer for your average Joe Sixpack to make a transaction.
From my own experience, and knowing what I'm doing, the OS runs a good bit slower than the tried and true green on black systems. Top that off with the annoying pointy finger and IE "click" noises, and you have an example of change for change's sake.
Of course, the only reason at all they seem to be using this new system is so they can bombard you with advertising while you're using the machine.
All and all, a bad change all around.
I saw one crashed the other day and was so amused that I took a photo of the screen. It's poor quality: taken with a phone, at night. The sheet of paper at the bottom of the picture was taped over the screen, saying "Out of order". Of course I was curious and peeled it down.

One interesting thing is how/why it was successfuly uptated (if the bank wanted to do it I don't think the dialog would be there).

I'll start working on modifying my ATM card's magnetic strip to overflow the ATMs card reader.
I think you were being funny but I actually develop ATM software and some of the code I have inherited from the previous idiots would have been succeptible to exactly that. It wouldn't get you any money unless you knew the internal protocols for dealing with the cash dispenser in addition to knowing how to exploit a buffer overflow (in which case you would likely know 10 other/better/easier ways to rip it off) but that is almost certainly a hole in more than a few machines out there.
The banking industry is one where cutting corners simply isn't allowed.
You'ld be surprized at just how cheap banks and money institutions can be. Although it wasn't a bank, I once worked for the largest government bonds firm as a sysadmin. Their clients were banks themselves. Bonds were traded in lots of 10 million and in one day you'ld get serveral thousands of transactions. I was amazed at just how much money use to flow through the systems I was running. As a brokerage firm, they made their commision with a few pennies on every transaction. They were making tons of cash daily. Money was everywhere, but what amazed me most was the equiptment. Many of the hub servers were old SPARC 5's and if it was a bigger client, they got a spanky Ultra 5. Not even servers! For such a critical app, I suggested they buy into Netra's or something teco grade that could withstand a beating. The response I got was it was too much money. I couldn't believe it. Here's they'd pull in 20 million in one day from a single client, and they couldn't spend $1000 to upgrade the server. Then it was explained to me by another admin who's worked that arena a while. He said the cheapest companies you'll ever work for (from a sysadmin perspective) will be banking institutions and financal firms. They're filthy rich, but you can't squeeze a penny from them.
That's been my only experience with being a sysadmin at a money institution, but from that experience, it wouldn't surprize me at all to hear how banks would opt for the lowest bidder for any project. Hell, these guys were so cheap, they'd try to avoid buying directly from Sun and go with some third party refurbish vendor. Just unbelievible how cheap they'd be....but they all wore very nice suites. And just so you know....yes....they're still in buisness and they're still the largest bonds brokerage firm in the world. Pretty scary from a tech perspective.
