I am developing an application where the NFC mobile needs to be used as Access Card. For this I need to write some data to the Mifare Card in Nokia 6131 and read back using a NFC Reader. The NFC Reader should be able to read the data from the mobile and grant access.
First of all I am not able to read or write to the Mifare 4K device of the Mobile. It says Secure Element Locked. How can I write and read to the Mifare Card in Nokia 6131?.
I also tried to unlock the secure element using Unlock Midlet, but still could not get it unlocked.
Has anyone faced this problem...
