I strongly suspect he is referring to UK Switch (now branded Maestro)
cards which until very recently were issued with (I think) a 19 digit
principal number. UK issued Maestro cards are now being switched over
to the 16 digit standard.

I got my replacement (NatWest) Switch/Maestro with chip&pin and 16
digits in December 2005 so hardly "very recently".

Did anyone get a chip&pin card with other than 16 digits ?
