What are the EPC Standards?
A. The Auto ID Center (now administered by EPCglobal) has developed a Class 1 standard for UHF systems to act as the foundation for EPC hardware. The standard is necessary to address user requirements: low cost hardware, writable tags, solid range and speed, global application, and open to many hardware vendors. Class 1 tags are expected to be the most widely deployed of all, as they are the backbone of the EPC system. The Center started with Class 1 as the foundation for its standard-setting efforts because it is crucial to make the Class 1 system as simple and low-cost as possible, while still leaving a forward path to interoperable higher-functionality systems.
