RFID is a following technology used to identify and authenticate tags which can be applied to any product, individual or animal. Radio frequency Identification and Detection is really a general term useful for technologies that make use of radio waves in order to identify objects and people. Intent behind the Radio frequency Identification and Detection system is always to facilitate data transmission through the portable device called tag that is read with the help of RFID reader; and process it depending on the wants of an application. Information transmitted with the aid of tag offers location or identification as well as other specifics of product tagged – purchase date, color, and price. Typical RFID tag features a microchip with a radio antenna, attached to a substrate. The RFID tags are configured to respond and receive signals from an RFID transceiver.

This permits tags to be read from a distance, unlike other types of authentication technology. The RFID system has gained wide acceptance in businesses, and is gradually replacing the barcode system.Basic RFID contains an antenna, transceiver and transponder. Antenna emits radio stations signals to activate tag and to see in addition to write information to it. Reader emits the radio waves, including one to hundred inches, on the cornerstone of used radio frequency and power output. While passing through an electronic magnetic zone, RFID tag detects activation signals of readers. Powered by its internal battery or by the reader signals, the tag sends radio waves back once again to the reader. Reader receives these waves and identifies the frequency to generate a unique ID. Reader then decodes data encoded in a built-in circuit of tags and transmits it to the computers for use.Active and passive RFID are different technologies but usually are evaluated together.
Although both of them use the radio frequency for communication between tag and reader, the way of providing power to tags is different. Active RFID makes use of a battery within tag for providing continuous capacity to tag and radio frequency power circuitry. Passive RFID on the other hand, relies on energy of radio frequency transferred from the reader to the tag for powering it. Passive RFID needs strong signals from the reader but signal strength bounced from the tag reaches low levels. Active RFID receives low level signals by tag but it can cause higher level signals to readers. This kind of RFID is consistently powered, whether in or out from the reader’s field. Active tags contain external sensors for checking humidity, temperature, motion along with other conditions. Like everyone else can tune a radio in a variety of frequencies for hearing different channels, RFID readers and tags need to be tuned into exactly the same frequency for communication. RFID systems use various frequencies but most commonly and popularly used frequency is low, high and ultra high frequency.It is imperative to choose the right frequency for a credit card applicatoin as radio waves work differently at various frequencies.
