Note: After a Kill tag command, the tag will be unusable. To change the password, the current password
must be given. If no password has yet been set, the default value is 0. The new password is entered in the
field of the same name, in hexadecimal format. Clicking on the Set password on selected tag button
replaces the old password with the new password. The deactivation password is entered in the field of the
same name by clicking on the associated button.
If the password is changed and the memory area in question is already protected by the access password, in
addition to the new password the access password must be entered in the Current password field.
Read / write data
This section offers detailed access to all the data areas of the tag. Access is obtained by entering the
selected memory bank, the address within the memory bank and the number of words, expressed as 16-bit
words.
If data are to be written, it must be entered in the Data to write field. The data mask allows only individual
bits on the tag to be changed. To do this, the mask must be entered in the Data mask field. The reader uses
this mask to change the data read from the tag at the points where 1 bits are written in the mask, and writes
the result back into the tag. The desired data can optionally be written to a single tag in the field or to all tags
in the field. If it is written to every tag in the field, these tags must all have the same configuration (lock and
password).
This GUI section also offers the possibility to read data from the selected tag or from all tags in the field. If
the tags in the field have differing passwords and are configured differently, the data must be read by
individual tags.
The next section deals in more detail with the saving of the individual memory areas.
Lock
The EPC Gen 2 standard provides security mechanisms for the tag data areas. This allows individual
memory areas and functionalities of the tags being secured with a password to protect it against access
and/or changes.
Under the Lock section the mask that specifies access to the areas in accordance with the EPC Gen 2
standard can be customized to suit the application. If no changes are required for an area, No change must
be selected in the respective drop-down menu. The areas are grouped as follows:
No. Parameter Function
1 Kill password Specifies whether or not a Kill password is necessary for deactivating the Tag. See
EPCglobal Class-1 Gen-2 standard for details.
2 Access

password is set, the Tag can be addressed in the open state condition. Further details
can be found in the EPC global standard.
3 EPC memory

the EPC.
4 TID memory
