Re: SiteCode or FacilityCode of iclass dump

The CSN does not normally have any relation to the encoded iClass card number. To get the facility code from the credential, you need to know first if the iClass data is stored encrypted or not. If so, you need to decrypt the data before you can read it. Once decrypted, the data is read the same way you would read an old HID prox credential. The only thing that will be missing is the prox header.
