Hex Is Not the Standard
The Answer
What is the answer? The solution is to employ standards. In 1999, 2-D bar codes migrated to ISO encodation. Once the complete standards were published, adoption was slow but ultimately OK. RFID must use standards to achieve the same global success for interchangeability. I told someone the other day that I was not panicking, and that person told me I should be. But I am not panicking, mostly because the ISO 18000-6C/EPC Gen 2 standard is far more mature for interoperability and less mature for interchangeability. I see rapid adoption and success with interoperability for EPC Gen 2 RFID, and I see improvement with interchangeability on the way.
The fact is that both EPCglobal and ISO have new standards being released this year, which are almost 100 percent focused on interchangeability issues. EPCglobal is finalizing version 1.5 of its EPC Tag Data Standard (TDS), while ISO plans to publish a revised version of its ISO 15962 standard, which defines rules for encoding data to RFID tags. The updated EPC and ISO standards will include information regarding programming user memory.
Additionally, several vertical industries are expected to publish ISO guidelines for programming the UII memory—that is, memory bank 01 (MB01)—as a counterpart to EPC. What's more, the Automotive Industry Action Group (AIAG) plans to issue Revision 8 to the B-11 automotive item-level standard. This revision will include 100 percent of the details to secure interchangeability within that industry for all versions of ISO and EPC encodation.
Next year's RFID Journal LIVE! conference should include many demonstrations of implementations for which interoperability and interchangeability are complete and global.
