Hi Not sure if i can get any help for this here but still wanted to try my luck
I am using ACS made ACR 122 contact less reader with NXP mifare 1k cards. I want to know how change the security settings on Mifare card with C# windows application. I basically want to change the default PIN.
Though ACS supplies easykey app with SDK it does not have source and I cant integrate into my application being developed.
Any one know how to change PIN programatically ?
