Radio Frequency Identification Device – RFID

Introduction

Radio Frequency Identification (RFID) is the utilization of radio waves to recognize the objects. Unlike barcode, in RFID one can find a product without virtually coming in touch with it. The tracking number is stored in a micro-chip, which is connected to the aerial. The chip is then enables to put on the air any tracking data to the receiver. Finally the information will be converted into a digital format, which is read by the computers.

A usual RFID tag holds a microchip attached to an aerial escalated on a substrate. The data storage capacity of a chip ranges from 64 bits to 2 kilobytes. For e.g., information about a manufactured goods or consignment-date of production, and destination, can be downloaded to a tag.

A reader is necessary to recover the data stored on an RFID tag. A reader is a device, which has one or more aerials that releases radio wave and take delivery of signals reversed from the RFID tag. The reader then forwards the data into digital form to attached computer.

RFID Advantage

Whether you are related to tracking record in a warehouse or keeping a large bunch of apparel assortments, there is a requirement of a completely automated data receiving and evaluation system which will help out to sustain track of precious assets and equipments.
RFID technology offers exclusive solutions to hard data tracking of record or equipment- specifically in applications, where optical based systems not succeed and when write/read capabilities are necessary. The technology is constantly developing, with unlocked designs becoming more and more accessible.

Benefits of RFID vs. Barcode

The barcode’s optical nature needs labels which can be detected by lasers. The straight line between reader and labels is usually difficult, not practical, or even unfeasible to attain in industrial atmosphere. In a move to achieve proper functionality, a barcode reader requires clean and clear optics, label must be spotless and free of scratch, and the label and reader must be rightly oriented to each other. On the other hand, RFID technology makes tag enabled to read from a larger distance, even in worst environments.

Additionally, the data imprinted on a barcode is set and cannot be distorted. On the other side, RFID tags have electronic memory as same as to the common computer or digital camera to hold data and this can changed or updated dynamically.

RFID presents particular features which are not accessible with any other automatic identification technologies. Albeit, not all RFID systems offer every single feature, following are few common advantages of RFID.

. Enduring identification or read/write ability
. Do not require contact or straight sight line for reading
. Practical resistance from incomprehensible paint, dirt etc.
. Automated functioning
. Broad range of tag alternatives and frequencies
. Reading capability ranges from few inches to several feet
. Tremendously high data reliability

RFID Applications can be used in many trades other than retail, which includes animal recognition, supple production (tracking and control), laundry tracking, asset identification, and many many more…
