I would like to build a system where you can use the Nokia 6131 NFC's internal card as you would use a regular mifare 1k card with an external reader. Can someone explain to me what is to be done? I've read that you can access the secure element only with a signed midlet. Does that mean i'd have to build a midlet as a proxy?
What I would like to know is how to build a real-life-working system, without the need to unlock the phone. The phone would be used as a rechargable card in a closed payment system.
