 RFID
Made Easy
New starter kit simplifies process of creating applications
using RFID systems
RFID is one of the fastest growing technologies
because it has so many advantages over older technologies such as bar
codes and magnetic strips. So, Kanda.com has introduced a new starter
kit for RFID that simplifies the process of creating applications using
RFID systems.
RFID tags come in many forms from flexible labels and key fobs to contactless
cards to suit the particular application. Apart from some specialist tags
that need backup power, most RFID tags obtain all their power through
RF induction, so they do not need batteries.
The read range of the tag is mainly dependent on the power of the reader
and its antenna size, but in most cases it is three to four inches. Tags
all conform to ISO standards that cover a range of frequencies from 125KHz
to 2.4GHz. The Kanda kit uses 13.56MHz tags that conform to ISO15693,
as this is a reliable mid-range standard with both read and write capabilities.
Apart from a programmer and reader unit, the Kanda RFID kit includes
an RF detector that gives an indication of the RF field strength near
a reader, which helps both in development and in the siting of units.
However, the most important part of the starter kit is the software package.
The protocol used is very flexible to allow engineers to design their
own systems to suit their needs, rather than being constrained by the
limitations of the software. As well as the standard read, write and lock
functions, the protocol allows for continuous read, and includes anticollision
algorithms that deals with multiple tags in the reader field
Obviously, a RFID tag system that is to replace bar codes or magnetic
swipe cards must be linked to new or existing software such as data bases
to be effective. Therefore, this Kanda kit includes Windows API software
and documentation to integrate the kit into a variety of software and
database platforms.
This Kanda.com RFID starter kit is a cost-effective way of designing
an RFID system for a wide range of applications from entry control and
membership records to stock tracking and movement recording.
