RFID Standard Compliance:

In order to avoid interferences from other RF applications like electric and radio equipments and

to achieve interpretability between different tags and readers, RFID system standards are being

developed. These standards deal with air-interface protocol, data content, conformance with

regulatory requirements, and application. Two major standards available today are Electronic

Product Code (EPC) Global and ISO/IEC standards.

• EPC Standards

EPC has specified standards for tag data content, communication between tag & reader (air-

interface protocols), reader protocols, Savant specifications, Physical Mark-up language (PML)

specifications, and Object Naming Service (ONS) specifications for HF and UHF ranges. There

are two versions of these standards. Version 1 is already in use and version 2(Generation 2) is

ratified and going to be adopted in near future. As per this standard, data is stored on the tag, in

the format as shown in Figure 14.

Version 1 is already in use and version 2(Generation 2) is ratified and going to be adopted in

near future. Companies like Texas Instruments, Impinj, Philips Semiconductors, Alien

Technology, Symbol Technologies and Intermec Technologies have announced their plans to

manufacture Gen 2 tags.
