Yes, this defeats the keylogger attack.

ING has had this for a while. I have wondered whether it is still
possible to get the contents of that text box, because presumably the
content of the box is your pin and not the letter-translated value.

However, it seems odd that they wouldn't go the next step and store
the translation algorithm in session and have the keypad output the
translated value of your PIN into the box (which would then be
translated back to your numeric PIN on the server).
