RFID (pronounced as separate letters) short for radio frequency identification. It is a technology, which uniquely identifies objects automatically using wireless radio communications.
Radio Frequency Identification (RFID) is a technique of distantly piling and recovering data by means of devices known as RFID tags. An RFID tag is a little object, like a sticky label, that can be integrated into a product. RFID tags hold antennas to facilitate them to accept and react to radio-frequency inquiries from an RFID transceiver.
What is RFID tags? What are the different RFID tags?
RFID tags are of two types: active RFID and passive RFID. Passive RFID tags don’t have their own power supply. The little electrical current stimulated in the antenna by the inward radio frequency scan gives adequate power for the tag to send a rejoinder. Because of power and cost factors, the rejoinder of a passive RFID tag is essentially concise. It is normally just an ID number (GUID). Shortage of its own power supply crafts the device very small. Commercially accessible products exist that can be implanted beneath the skin. The least such devices commercially accessible measured 0.4 mm × 0.4 mm, and thinner than a sheet of paper. Such devices are virtually undetectable. Passive tags have practical read ranges that differ from about 10 mm up to about 5 meters. Passive tags are cheap to manufacture.
Active RFID tags, ought to have a power source, and may have longer ranges and larger memories than passive tags, as well as the capability to accumulate additional information sent by the transceiver. The smallest active tags are about the size of a coin. Many active tags have convenient ranges of tens of meters, and a battery life up to several years. While the cost factors of passive tags over active tags are noteworthy, other factors including accuracy and dependability make the use of active tags very common today.
A number of nations have anticipated embedding RFID devices in new passports to ease proficient machine reading of biometric data. The RFID-enabled passport distinctively identifies its holder; in the proposal currently under thought, the RFID tag will also comprise a range of other personal information (More info http://www.bigsquid.org)
BIGSquid RFID
BIG Squid RFID is not merely integrating various RFID middleware (tags and readers) with our own products, but we have formed partnerships with other leading companies that enable us to provide supply chain solutions for various clients. BIGSquid RFID provides solutions to various industries like pharmaceutical, manufacturing, textile etc., across the globe.
BIGSquid RFID is similar to bar code technology by automatically collecting information about a product or transaction quickly, easily and without human error. Lets understand some common differences between RFID and Bar Code.
BIGSquid RFID and Bar code are both identification technologies that hold data that is accessed by some type of reader. In actuality, they complement each other very well and can be used effectively side by side in many applications. Bar code is an optical technology and RFID is a radio technology. However, unlike barcode technology, it provides a contact less data link, without need for line of sight—for example articles inside a cardboard box—or concerns about harsh or dirty environments that restrict the use of bar codes. Just like bar code, RFID tags are available with different memory sizes and encoding options. The ways these technologies exchange data account for most of the differences between RFID and bar code and help determine where each identification technology is best put to use.

BIG Squid RFID uses an integrated microchip and antenna that reads information. The combination of the chip and antenna is called an RFID tag. There are two types of tags, and therefore two types of systems, active and passive. In passive systems, which are the most common, an RFID reader transmits an energy field that "wakes up" the tag and provides the power for the tag to operate. In active systems, a battery in the tag is used to boost the effective operating range of the tag and to offer additional features over passive tags, such as temperature sensing. The radio waves that are sent back and forth between tag and transmitter contain the data in the tag, and this data is then converted by the reader and transferred into a computer system.
Companies are focusing on passive UHF tags, which costs less than 50 cents today in volumes of 1 million tags or more. Their read range isn't as far -- typically less than 20 feet vs. 100 feet or more for active tags -- but they are far less expensive than active tags and can be disposed of with the product packaging.

The Key Components to an RFID System are a number of components including tags of different sizes catering the different industrial needs, RFID readers and system software.
An RFID reader, usually connected to a Personal Computer, serves the same purpose as a barcode scanner. It can also be battery-powered to allow mobile transactions with RFID tags. The RFID reader handles the communication between the Information System and the RFID tag.
The BIGSquid RFID Software collects, permutes and stores the data collected from the tag in a back end like MySQL, SQL Server etc. This is usually similar to any other data collection software.
