RFID: The New Technology


Radio frequency Identification and Detection is a general term used for technologies that make use of radio waves in order to identify objects and people. RFID is a tracking technology used to identify and authenticate tags that are applied to any product, individual or animal.

Purpose of Radio frequency Identification and Detection system is to facilitate data transmission through the portable device known as tag that is read with the help of RFID reader; and process it as per the needs of an application.

How RFID works

There are two types of RFID tags: active and passive. When most people talk about Radio frequency Identification. they talk about passive tags, in which a radio frequency is sent from a transmitter to a chip or card which has no power cell but uses the transmitted signal to power itself long enough to respond with a coded identifier.

Passive RFID tags are lacking in power supply of their own whereas Active RFID tags are full with power source and may have extensive ranges and sizable memories than passive tags and they have more space to accommodate extra data sent by transceiver.

Choosing best RFID tags for your application

With so many technologies, standards and formats, the range of options open to a user are very wide indeed. As the market is filling with hundreds of types of RFID tags , there is no simple way to sort them all and pick the perfect one. However, we have gathered criteria that will help you with your selection. The two different technologies of RFID are Active RFID and Passive RFID. Active RFID : Active RFID can be used in applications where multiple tagged products have to be monitored over larger areas, or scanned at a fast pace as they move through a particular facility. Passive RFID : In passive RFID systems the reader and reader antenna send a radio signal to the tag. The RFID tag then uses the transmitted signal to power on, and reflect energy back to the reader It helps you to choose the best RFID tag  Choosing a Frequency you need to consider frequencies when selecting RFID tags . The higher the frequency, the more difficulties you’ll have with ma...
