The following tables show possible combinations of the "r/w" and "w" flags with "p" flags and
the meaning of the combination for a memory bank.
The transponder is in the "open" status when it is identified and in the "secure" status when
its access password is verified.

In the example above "lockMask = 11 1111 0000" (hexadecimal 3F0). This means that only
write access to the memory locations Kill, Access and EPC is possible. The fields for
"lockAction" are "10 1010 0000" (hexadecimal 2A0), which means:
● Kill password
Read and write access is possible from the "secure" status but not from the "open" status.
The access password for the transponder must be known before the Kill password can be
read or modified.
● EPC memory bank
Write access is possible from the "secure" status but not from the "open" status. The
access password must be known before a new ID can be written to the transponder. You
will find more detailed information on "epcGen2LockAction" and "epcGen2LockMask" in
the "EPC Radio Frequency Identity Protocols Standard Specification".
