RFIDRADIO FREQUENCY IDENTIFICATION BY: VATSALYA SAXENA
Presentation Objectives:• Explain technical principles behind RFID• Provide overview of RFID technology• Discuss: – Forces driving the adoption of RFID – Challenges RFID deployment must overcome – The future
What is RFID?• Radio-frequency identification (RFID) is an automatic identification method using radio waves.• RF signals transmitted by the transceiver activates the transponder, which transmits data back to the transceiver.• Requires no line-of-sight (like bar-codes)
The RFID System1. Tag.2. Reader.3. Reader antenna.4. Host and software system.
Types of Tags– Passive • Operational power scavenged from reader radiated power– Semi-passive • Operational power provided by battery– Active • Operational power provided by battery - transmitter built into tag
READERA device that is used to interrogate an Tag.Basic components areA scanning AntennaA transceiver with a decoder to interpret datahelps in personalize & read data.
FrequencyLF band: 125 and 135 kHz--LF generally use passivetagsHF band 3 MHz to 30 MHTypical Frequency: 13.56 MHz--HF system uses passivetags . UHF band:300MHZ to 1GHZTypical Frequency :915 MHz--Uses both active andpassive tagsMW band > 1GHZTypical freqency:2.45 GHZ
APPLICATIONS1. Tracking Books in Libraries.2. Passports ( passports recently).3. For toll booths (or any “pay for entry” System).4. Animals Tracking.
Portal application:- Bill of lading Material tracking Bill of Lading Material Tracking
Advantages• Contactless. An RFID tag can be read without any physical contact between the tag and the reader.• Absence of line of sight. A line of sight is generally not required for an RFID reader to read an RFID tag. Wide data-capacity range. Support for multiple tag reads.
DISADVANTAGES• High cost.• Tag collision.• Reader collision.• Impacted by environmental factors.
FUTURE RFID, is an emerging technology which can be used for a variety of applications. However, the potential for abuse of this technology is vast and requires careful consideration to avoid. RFID IS A SUPPORTING TECHNOLOGY--- NOT A COMPETING !!
