I'm quite new to RFID and protocols or reading them. We have some access&time control in our company. Product we have, contains older iClass door readers and newer time clock registrator (containing iClass SE reader). It should detect cards (iClass 15693/2k bit and 16k bit; iClass 14443B/ 16k bit).
I need to order tokens, but not original iClass key, wich is expensive and seeking some alternative. So i order some 14443A keys from Amazon, wich worked really fine on door readers(old iClass reader) but not in time registrator(where i think there is newer reader). Next i try to order via chinese store, Keys with ISO15693 protocol- not working on a door neither registrator. What i'm doing wrong, does iClass has such security so no copies only original? Could i reproggram keys, by Proxmark reader maybe?
Thanks for your help,
Br, Andrej
