Radio Frequency Identification (RFID) Technology

Introduction

Business today, while searching for ways to improve their daily processes, both logically and physically. This may include better reporting of income, return on investment using the cost technological solution. Radio frequency identification device (RFID) is a technology that many companies are considering implementing.

Description Radio Frequency Identification Device (RFID)

The Department of Homeland Security determines Radio frequency identification device (RFID), as wireless systems that allow the device to read information contained in the mobile device or "tag" - from a distance without physical contact or requiring a line of sight between the two. RFID provides a method for transmitting and receiving data from one point to another. "RFID is an automatic identification method relying on storing and remotely Getting data using devices called RFID-tag or transponder.

Historically, RFID has been around in 1920, however, the first known device was invented in 1945 and was said to be used as a tool for espionage, however, this tool was just a listening device, not the ID tag. Real RFID system was developed around 1960.

RFID-System

RFID-system comprising tags, transponders, transceivers and applications to extract and read data from a transponder tags and application software. In addition, the human factor must be qualified and trained for the application.

Radio Frequency

Radio key for system performance RFID. The frequency determines the speed of communication and distance tag reader. Specific objectives are subject to various frequencies of RFID.

There are four types of radio frequency: low, high, ultrahigh and microwave. Band of low frequencies from 125 to 134 kHz. This group is suitable for short distance, such as anti-theft systems, animal identification and the car unlock the system. For example, pets can be implanted with small chips used to find information about the owner lost a pet.

High frequency is clocked at 13.56 MHz and provides high accuracy within a 3-foot reduces the risk of incorrect reading of tags. High frequency is designed to track the material, airline baggage tracking, as well as building management access.

Microwave frequencies are about 900 MHz and can be read at greater distances from 3 to 15 feet. These tags are more sensitive to environmental factors than any other tag on another frequency. These tags are primarily used for supply chain applications due to its reading speed and range. UHF tags can be from 100 to 1000 tags per second and there are efforts to increase this ...
