MIFARE DESFire comes in different sizes 2K, 4K and 8K. I am trying to create multiple applications and files. since the specification says a DESFire can have 28 different application and 16 different files in each application, so the question is will the 4K memory is also used to store the application and file header?? or the 4K is only for file data ? Also the 14 keys per application are stored in same 4K memory or what?
