The Chasm Between RFID Standards and Implementation
Shown below is the data encoded within the 2-D symbol above. The data was separated into lines and spaces for human readability; they are not encoded in the data.
Figure 3: Data Encoded Within the "As Built" 2-D Data Matrix
The data, as represented in Figure 3, would be placed into an RFID tag as follows:
• The first line of data is called the message header, and tells the decoder (either bar-code or RFID) that the data following is constructed according to the rules of the ISO 15434 standard, which specifies the structure, syntax and coding of messages and data.
• The second line is the completely assembled gas tank's Unique Item Identification number, and will be placed into MB01 of the RFID tag as this gas tank's birth record (UII).
• The third through seventh lines provide information regarding each individual subassembly of the gas tank, and will be placed into MB11 of the RFID tag as additional information about that gas tank. They represent the subassembly's part number (P), its manufacturer (12V) and its traceability code (T).
• The EOT at the end of the data indicates the end of the overall message.
Whether the data comes from a bar code or an RFID tag, it will be the same.
