Introduction to Radio frequency Identification:

Hi and Welcome on Radio-FrequencyID.com.
You will discover the 21st century technology finally available.
RFID corresponds to Radio frequency identification.

How RFID work?

The principle is simple: a mini chip, which doesn't need electricity to stock information; this can be the modus operandi of your company or any data.

Then an RFID receiver: interprets and reads the content of the chip and an antenna for tracking amplification (see specification)***

From there on, everything is possible:
For example, the innovation of fujitsu which has developed the Tag front system, which deploys washable soft linen RIFD, tags for tracking rentals and returns of uniforms.

These tags ensure real time tracking of clothing inventories. With high readability, these tags can be read from over four feet and multiple tags can be scanned without manually touching the piece of clothing.

With Storage from Advanced Research Company which is an RFID based storage cabinet indicating the items inside it and the ones which are missing and even providing information about who accessed the cabinet.

Technical description about RFID:

RFID (Radio Frequency Identification) is used in all areas of automatic data capture allowing contact less identification of objects using RF. With applications ranging from industrial automation, access control, animal identification, ePassport and ticketing, RFID technology solutions are receiving much attention in the research and development departments of large corporations.

RFID is a major growth area in auto ID, providing the technology behind contact less smart cards, production automation and the electronic supply chain. RFID helps to prevent attackers from exploiting security beaches for monetary gain (hacking a store's RFID system would allow a hacker to lower the pricing on any product); how to protect the supply chain (malicious-mischievous hackers can delete-alter-modify all identifying information for an entire shipment of products); and how to protect personal privacy advocates fear that RFID tags embedded n products, which continue to transmit information after leaving a store, will be used to track consumer habits).

*** An antenna or coil A transceiver (with decoder) A transponder (RF tag) electronically programmed with unique information.

The Advantages:

The significant advantage of all types of RFID systems is the non-contact, non-line-of-sight nature of the technology. Tags can be read through a variety of substances such as snow, fog, ice, paint, crusted grime and other visually and environmentally challenging conditions, where barcodes or other optically read technologies would be useless. RFID tags can also be read at remarkable speeds, in most cases responding in less than 100 milliseconds. Though it is a costlier technology (compared with barcodes) RFID has become indispensable for a wide range of automated data collection and identification applications that would not be possible otherwise. Developments in RFID technology continue to yield larger memory capacities, wider reading ranges and faster processing. It is highly unlikely that the technology will ultimately replace barcode-even with the inevitable reduction in raw materials coupled with economies of scale. The integrated circuit in an RF tag will never be as cost -effective as a barcode label. However RFID will continue to grow in its established niches where barcodes or other optical technologies are not effective. RFID tags come in a wide variety of shapes and sizes. Animal tracking tags inserted beneath the skin, can be as small as a pencil lead in diameter and one-half inch in length. Tags can be screw-shaped to identify trees or wooden items, or credit-card shaped for use in access applications. The anti-theft hard plastic tags attached to merchandise in stores are RFID tags. In addition, heavy-duty 5-by 4 by 2 inch rectangular transponders used to track intermodal containers or heavy machinery, trucks and railroad cars for maintenance and tracking applications are RFID tags.

Active Tags:

Active RFID tags are powered by an internal battery and are typically read-write: the tag data can be rewritten or modified. An active tag's memory size varies: some systems operate with up to 1MB of memory. In a typical read-write RFID, a tag might give a machine a set of instructions and the machine would then report its performance to the tag. The battery-supplied power of an active tag generally gives it a longer read range. The trade off is a greater size, greater cost and a limited operational life which may yield a maximum of 10 years,

Passive Tags:

Passive RFID tags operate without a separate external power source and obtain operating power generated from the reader. Passive tags are consequently much lighter than active tags, less expensive, and offer a virtually unlimited operational lifetime. The trade off is that they have shorter read ranges than active tags and require a higher-powered reader. Read-only tags are typically passive and are programmed with a unique set of data (usually 32 to 128 bits) that cannot be modified. Read-only tags most often operate as a licence plate into a database.

Frequencies

Their frequency ranges also distinguish RFID systems. Low-frequency (30 KHz to 500KHz) systems have short reading ranges and lower system costs.
These are mostly used in security potential, asset tracking and animal identification.

High-frequency 9(850 MHz to 950MHz and 2.4 GHz to 2.5 GHz) systems are used for railroad car tracking and automated toll collection.
The high-frequency RFID systems incur higher costs.
