How the Nokia 6131 NFC internal Mifare 4k area or the internal Java Card area could be utilized for storing critical information?
It depends totally of the application type and technical infrastructure of the environment, where the application is going to be used. However, following things could be considered: – Mifare 4k area is just a memory with access control, and typically it is simpler to implement. – Java Card provides high security environment and can execute code, which means it can be used for more complex applications. Java Card supports standardized and well known security algorithms. – Managing several applications on Mifare side is challenging. – On Java Card side, the amount of applications is the amount, which can fit into Java Card memory.
