Topic: How can I lock authentication key for writing in Ultralight C tags?
I have updated the authentication key of the ultralight C tag. After that i am able to authenticate and read/write successfully. I need to know what command i will send to tag to lock the authentication key sectors i.e 44,45,46,47 for writing. Though I am doing it in C# but any example in java can also help me to identify what exact data i will write to block 40 (which consists of lock configuration i think)
