Auto-tabbing is contrary to the normal expected behaviour of the browser, and should therefore ont be used. I remember seeing a short video from a usability/accessibility test done by bunnyhop..aeh... www.bunnyfoot.com which showed exactly this: some online banking form with multi-field auto-tabbing CC entry...and practically all users (both visually impaired, 100% blind and 'fully abled') ran into problems there.

I'd say that the best method, imho, is to stick with a single field and do some fairly simple reformatting server-side (strip out any non-numerical characters and spaces, then - if required - split the string back up into numerical groups).
