Re: iclass printed serial number and CSN

That would be the wiegand printed on your card,  not the CSN.

Dear iceman,
do you mean the printed icalss card number is the actual wiegand that the iclass reader will decrypted and sent to control board? 

If this is true, then it will be very interesting to have fun with SE and ER iclass.

Depends but if its a preprogrammed card, the printed number could be the wiegand data.   HID offers lots of options when it comes products.  There is no general rule for it.
