BIGSQUID RFID : Emerging to RFID Enterprise Solution
About RFID Radio frequency identification or RFID, is a generic
term for technologies that use radio waves to automatically
identify
people or objects. There are several methods of identification,
but the most common is to store a serial number that
identifies a person or object, and perhaps other information, on
a microchip that is attached to an antenna (the chip and the
antenna together are called an RFID transponder or an RFID tag.
Visit http://www.bigsquid.org for more information on this).
The antenna enables the chip to transmit the identification
information to a reader. The reader converts the radio waves
reflected back from the RFID tag into digital information that
can then be passed on to the computers that can make use of
it.
Objective The objective of any RFID system is to carry data in
suitable transponders, generally known as tags, and to retrieve
data, by
machine-readable means, at a suitable time and place to satisfy
particular application needs. Data within a tag may provide
identification for an item in manufacture, goods in transit, a
location, and identity of a vehicle, an animal or individual.
By including additional data the prospect is provided for
supporting applications through item specific information or
instructions immediately available on reading the tag.
The system requires, in addition to tags, a means of reading or
interrogating the tags and some means of communicating the
data to a host computer or information management system. A
system will also include a facility for entering or programming
data into the tags. Quite often an antenna is distinguished as
if it were a separate part of an RFID system. While its
importance justifies the attention it must be seen as a feature
that is present in both readers and tags, essential for the
communication between the two. To understand and appreciate the
capabilities of RFID systems it is necessary to consider
their constituent parts. It is also necessary to consider the
data flow requirements that influence the choice of systems and
the practicalities of communicating across the air interface. By
considering the system components and their function within
the data flow chain it is possible to grasp most of the
important issues that influence the effective application of
RFID.
However, it is useful to begin by briefly considering the manner
in which wireless communication is achieved, as the
techniques involved have an important bearing upon the design of
the system components.
Components of RFID
RFID Reader : The Reader is a radio frequency device used to
read data from the microchip contained in the RFID tag. RFID
readers use a
variety of methods to communicate with tags. The most common
method for reading passive tags at close range is called
inductive coupling. Simply put, the coiled antenna of the reader
creates a magnetic field with the coiled antenna of the tag.
The tag draws energy from this field and uses it to send back
waves to the reader, which is turned into digital information -
the tag's electronic product code. A Reader comprises of a
transmitter, receiver, control module and communication
functions, sometimes called a transceiver in
radio terms for it to link to a controlling PC. Readers should
have an attached antenna, which is used to transmit and
receive the radio frequency signal. Each reader is accompanied
with PC compatible software that allows the user to read and
program tags. Win 2K, XP, ME are some of the operating systems
compatible with our Readers.
RFID Tag : An RFID tag or transponder is a wireless system
composed of an electronic chip (semi-conductor device) with a
memory where
data can be stored. The memory can be permanent or volatile.
They are classified within two frequency ranges, namely 125 KHz
(low frequency) and 13.56 MHz (high frequency).
The RFID Business Case: RFID in the Receiving Business Process:
RFID readers are placed in the receiving area to monitor pallet
and case RFID tags.
The RFID readers verify the pallet license plate, count the
units on the pallet, identify the vendor, and confirm the
purchase order receipt without human intervention in the
business transaction. RFID in the Conversion Business Process:
RFID readers can be placed along the flow path of a
manufacturing process.
Work-in-process, or WIP, can be enabled by RFID tags for
tracking and monitoring the conversion of raw materials and
intermediates into finished goods and stock-keeping units. This
material information is integrated with the ERP production
order transaction process to track manufacturing steps and issue
production transactions. RFID in the Customer Order Picking
Business Process: Forklift drivers will use RFID readers to
select case and pallet
materials to pick order and assemble the shipment. Elimination
of staging and verification processes can yield savings.
This material information is integrated with the ERP warehouse
and order management process to update the customer order pick
list.
RFID in the Shipping Business Process: Forklift drivers and
warehouse bays will use RFID readers to track case and pallet
materials onto trucks. This material information is integrated
with the ERP warehouse and order management process to update
the customer order shipment. The RFID value proposition
propagates if the RFID infrastructure is leveraged by other
enterprises in the downstream value
chain.

BIGSquid RFID Tag
BIGSquid RFID Tag is an Industrial and Logistics RFID
Transponder. BIGSquid RFID Tag's unique design gives it,
infinite life
and makes it nearly indestructible as opposed to conventional
Tags. (More info http://www.bigsquid.org )
BIGSquid RFID Reader
BIGSquid is an industrial grade RFID Reader and an intelligent
device. BIGSquid Navigator has built-in features, which allows
easy integration in large layouts as opposed to normal readers.
Navigator is remotely programmable and controllable and can
transmit the RFID TAG information to long distances directly
without using any additional interfaces or hardware. (More info

BIGSquid Reader Controller Modules
BIGSquid Reader controller modules are an essential companion
when you deploy multiple RFID readers in geographically
separated locations. The reader controller modules allow you to
control readers remotely using multiple digital I/O from
other processes or machines. (More info http://www.bigsquid.org )
RS232 to Ethernet converter
The rs232 to Ethernet converter is a first-generation Serial
Device Server that externally connects any existing serial
device to an Ethernet (TCP/IP) network. The rs232 to Ethernet
converter features a compact and stylish design. (More info

BIGSquid RFID Middleware Server
The Server part of the BIGSquid RFID collects the tag
information and updates in the database. The server will be
running in
the backend as a Service. Whenever there is a read at any
particular reader it will be validated and will be stored in
database against particular inventory.
The server will read the tag value precisely and will not miss
any valid data. The validation part first checks whether the
data that has been captured is valid or not and then it will
check for the object or inventory that tag value represents and
stores the tag value against that inventory or object. Please
