Q: What is the difference between passive and active tags?
Passive tags rely on the airwaves emitted by RFID readers as a power source, instead of
relying on battery power. This essentially gives passive tags an unlimited lifespan. Power
is derived from the active RF reader’s electromagnetic field. Without a battery, passive
tags are generally smaller and lighter in comparison to active tags. But the read range is
shorter and much smaller than that of an active tag.
Active tags capture attention of the reader and function using battery power. A battery is
either connected to, or built into the tag. Active tags can operate over greater distances
but are usually more expensive due to the cost and size of the battery.
WHAT ARE THE PROPOSED STANDARDS OF RFID?
Q: Who is EPCglobal?
EPCglobal, a global RFID organisation, is in charge of establishing EPC (electronic
product code) standards. The organisation is a joint venture between EAN International
and Uniform Code Council (UCC) as our implementation partners have many years of
experience in administering global standards. The EPCglobal Network employs Electronic
Product Code™ (EPC) and Radio Frequency Identification (RFID) technologies. These
standards offer the potential for increased efficiency and accuracy through automation,
tracking and security through improved visibility and collaboration by providing a globally
standard framework for information exchange.
Q: What are the key goals of EPCglobal?
The EPCglobal Network aims to enable trading partners to minimise shrinkage and
shortages, accelerate order processing and increase responsiveness to consumer
demand by enabling the flow of real-time information about goods enabled within the
