RFID Standards

RFID will be one of the most important standards in the decades to come. The promise of “Internet of Things” has caused major countries and geopolitical entities to support various of national and regional standards. EPC standard is mainly back by the US vendors and ISO standard more widely supported and accepted in Europe. Japan has UID (Ubiquitous ID). China has recently announced its intent to create its own RFID standards. Even though EPC has the strongest commercial support, the true global standards are still under development and will subjected to geopolitical force.

Technology Standards

Deals with the technological features, such as the air interface communications format, data exchange protocols and data structure to ensure interoperability of systems provided by different manufacturers.

Air interface Standard
Air interface standard defines the interaction between RFID tags and readers. The following four standards built on the Internet infrastructure are related to methods to retrieve information about a particular item:

  • Savant servers
  • Object Naming Service (ONS)
  • Product Markup Language (PML)
  • EPC Information Service
ISO 18000 parts 5 and 6 cover the way readers communicate with tags, for RFID tags used to track items.

EPC Standard
EPC (Electronic Product Code) is the next generation UPC (Universal Product Codes). The coding gives each item a unique number as identification.

Application Standards

Deals with the way in which technology or systems are to be used in particular applications to ensure that data created at a source can be understandable by any recipients and to constrain the associated technology standard in terms of performance or other features.
