Hi Peter,
I've never said that EMV is 100% compatible with ISO 7816-4 (because it is
not) but Hennie was looking for documentation about data storage in
smartcards. I think that data storage for EMV and ISO 7816-4 is basically the
same : MF, DF, EF, records... Nevermind which protocol you're using, the
structure of files doesn't depend on it.
