What is the best approach to emulate multiple mifare cards on the Nokia 6131 NFC? I want to build an application which can emulate multiple cards. The user must be able to select the one to be used each time he stands in front of a reader (I see no other way to automate this process).

As far as i understand it, the phone has ONE internal mifare 4k card.
- Does this mean that emulation multi cards is only possible by changing the contents of the memory each time?
- The ID of the card will stay always the same? So appliactions which use only the ID of the card will use all the same ID?
- Is it also possible to use the secure element for the cards? Then how would i be able to move the data from the SE to the internal mifare card each time, without breaking the security?

Best regards,
