jquery plugin to capture user input via virtual keyboard

Most of the bank sites have a keyboard (primaril开发者_开发知识库y with alphabets) which let them select user input (usually for their passwords). Is there a jquery plugin available which we can use for this purpose?

But I think it would be a lot of fun to have a go at making one yourself. Should be as easy as a loop that assigns key codes to some divs and a function that writes the value of those key codes in a chosen field.
