The Chasm Between RFID Standards and Implementation
AIAG B-11 Rev 8
Automatic identification and data collection (AIDC) technologies have been critical to the automotive industry's day-to-day processes for many years. These technologies include linear bar codes (Code 39, Code 128), two-dimensional symbologies (QR, Data Matrix), direct part marking (engraving, etching and peening) and RFID.
One critical factor in successful RFID implementations is to make its use transparent with respect to the above-mentioned AIDC methods. The goal is to make the data the important part, and to make the data carrier device irrelevant, whether it's a bar code or RFID tag. To do this, a standard way of creating the information and putting it on the data carrier is needed—one song, with everybody knowing the notes, but playing them on different instruments.
The B-11 Item-Level RFID Standard was created in 2001 as a solution to one very specific problem—namely, how to track tires. Since 2001, with global input, B-11 has grown to cover not only tires, but any item or object. Revision 8 of the standard explains the global answer to a global question: How do we use RFID to carry data interchangeably and seamlessly with other AIDC methods?
Specifics
There are four data blocks on an ISO/IEC 18000-6 Type C / UHF EPC Gen 2 RFID tag: MB00, MB01, MB10 and MB11. (The numbers are actually binary numbers and are usually followed by a subscript 2; MB00 is the first memory block, and MB11 is the fourth memory block.) To maximize the benefits, there are two data blocks that need to be used together when storing various data elements: the Unique Item Identification Memory Block (MB01, the second memory block) and the User Memory Block (MB11, the fourth memory block).
An item's unique item identification, or name, is placed into MB01. Additional data about that item is placed into MB11 (see Tag Memory Banks—MB01 and MB11).
