Your choice of system class is less daunting than it might appear. For mandate compliance drivers such as Wal*Mart and the DoD, the existing C1 and C0 systems meet their current application requirements. The existing standards will continue to provide the performance necessary throughout 2007, or as long as compliant tags are available at a reasonable cost. Due to the rapid decrease in cost and increase in availability of the C1G2 tag, most early adopters have upgraded their systems to support C1G2.
Today, Class 1 Generation 2 has emerged as the current preferred choice by virtue of offering the highest performance at the lowest cost. Several recent breakthroughs in antenna design have also created a significantly smaller UHF tag than previously available. These small tags are enabling the development of new UHF applications in pharmaceutical, point of sale, and small item tagging.
Closed Loop RFID systems
In addition to the mandate (Open Loop System) driven RFID technologies and solutions, there is a broad selection of Closed Loop RFID technologies using UHF and alternate frequencies to serve other industries. A Closed Loop solution does not require adherence to any mandates or compliance standards.
Some Closed Loop applications include:
- LF (low frequency) systems for animal tagging
- HF (high frequency) systems for tool tracking
- Solutions using RFID tags encapsulated in resins and ceramics to resolve extreme temperature or environmental issues
- Solutions for tagging books, totes, containers, pallets, and other reusable assets
- Solutions with active tags (featuring little batteries inside) that can be read from helicopters, to track animals in the wild
- Solutions for tracking children on school busses and in amusement parks
- Solutions for tracking patients in a hospital
The list is only limited by the imagination of the solution designer. In fact, many people use some aspect of RFID in their everyday lives, as when they start their cars (with a smart key and a reader in the ignition), or open the office door (with the familiar plastic ID card).
