Barring rational reasons that this is the wrong approach, (i.e., if
you've got a keylogger on your system other things are probably
compromised such that a remote user could be viewing your entire
session) your solution seems sound and accessible.
Keyboard access works. I can scale the display with the font size. Works
when style sheets are disabled.
I didn't see a submit feature with the JavaScript disabled, but assume
you are simply prototyping a potential solution. I'd hate to have a
submit event on the last dropdown in case I accidentally hit the wrong
number.
There are always reasons, some unsound that users want to implement
things. You've done a good job making their content accessible.
Excellent!

Subject: [WebAIM] Keylogging and PIN entry fields
I had to deal with a client requirement today that puzzled me. The
product is a banking application and there will be a login that
requires a 4 number pin.
Now, normally I'd have used a password field for that - as it is the
most accessible solution - but the client requested a pin entry pad
like the ones you see on cash machines.
The users should use their mouse to enter the pin.
The reason (not marketing as I originally thought): Keylogging
software that might record the pins users enter. Therefore as a safety
measure the pin pad was requested.
I came up with a DOM solution for the issue and would appreciate some
feedback and testing of it. If it were to be considered good, I will
release it as a download later:

I really wonder if there is a non-JavaScript dependent solution to
this problem. Well, 4 dropdowns with 0 to 9 would be one, but that is
as trackable, isn't it?
