IT2200-series tag programming information.
Identification, Serial Number, and the Global Password
TransCore documentation and/or host software references a tag identification number
(ID) that corresponds to the Title 21 ID. The Title 21 ID is a unique identifier used by
radio frequency identification systems in California. This is found in the first 8 hexa-
decimal characters (32 bits) of the tag’s general Page 1. In all IT2200-series tags, this
ID is either the same as the serial number from Page 0, or other application specifica-
tions.

The tag serial number (S/N) is the first 8 hexadecimal characters (32 bits) in general
Page 0. The global password is 64 bits long and the default is generated by repeating
the serial number twice. Once this global password is known, it can be used to change
read and write passwords on any of the general pages of data in the tag, change which
frames are designated nonvolatile, and lock pages of data so that they cannot be
changed unless the page is unlocked first using the global password.

These two identifying numbers are in addition to any customer-specific ID numbers.
Most of the customers that use the IT2200-series tags employ one of the other general
pages of data available in the tag to store their own unique ID number, which usually
corresponds to a patron account number.

The global password in the IT2200-series tag acts like a master key, which can be
used to perform crucial tag operations and is meant to be controlled by the owner
agency. It has a default setting that is created from the tag’s unique serial number, but
can be changed by the owner agency, if desired. Table C-1 shows the tag page layout.
