2: By default, the Read and Write keys are FF FF FF FF FF FFh.

5: It is also advisable to separate the Read key and the Write key, and not configure both to be the same. By separating the Read and Write key, this will allow users more control over the security levels between reading and writing the cards; as the permission of writing and/or re-writing the Card ID can be given to higher level security personnel, while the Read key can be given to lower authority personnel to grant access to the card holder.
