RFID: The definition
• Short for radio frequency identification, RFID is a dedicated short range communication (DSRC) technology. • The term RFID is used to describe various technologies that use radio waves to automatically identify people or objects. • RFID technology is similar to the bar code identification systems we see in retail stores everyday; however one big difference between RFID and bar code technology is that RFID does not rely on the line-of-sight reading that bar code scanning requires to work.

Components of RFID Tag
• Chip tags consist of a microchip and a coupling element – an antenna. • Chip tags can be both read-only (programmed during manufacture) or, at higher complexity and cost, read-write, or both. • Chip tags contain memory. • The size of the tag depends on the size of the antenna, which increases with range of tag and decreases with frequency.
4
Components of RFID (Cont.) Reader
• The RFID Reader, which is also widely known as interrogator, sends RF signal to request tag for transmitting information within the chip. • The response received from the tag is then translated in to digital form and send to the application software. • Different types of readers are fixed readers, handheld readers, network readers, readers embedded in other mobile devices etc. • Some interrogators not only read, but also remotely write to, the tags.
5
Components of RFID (Cont.)
Antenna • The antenna transmits an electromagnetic field, which activates the tag. • The antenna also receives the data from the tag and sends it to the reader. • Tags also require an antenna to transmit the information to the reader and to receive information from the reader if it is a rewritable tag.
6
Components of RFID (Cont.) Middleware
• Middleware is the interface needed between the interrogator and the existing company databases and information management software.

Difference between RFID and Bar Codes
• The big difference between the two is bar codes are line-of-sight technology. That is, a reader has to "see" the bar code to read it. On the other hand Radio frequency identification, doesn’t require line of sight. RFID tags can be read as long as they are within range of a reader.
13
Difference between RFID and Bar Codes • The bar coding scans a printed label with optical (Cont.) laser or imaging technology, while RFID scans, or interrogates, a tag using radio frequency signals. • Bar codes utilize one-way, serialized, and periodic data. RFID utilizes two-way, parallel, and real-time data.

RFID Applications Following are the current uses/ applications of RFID:• Employee identification cards • Amusement Parks • Automobiles- Use of RFID tags in keys • RFID in Supply Chain Management • RFID in Hospitals- To track Doctors, Patients etc. • RFID Chips for animals • RFID in Retail Stores- To track real time inventory.
15
RFID Applications Continued.. New emerging trends in RFID: • • • • • • • • •
Supply chain tracking Retail and inventory management Baggage handling Credit cards Health care ID and medical research data Smart passports Import/export processes Auto ID for tolls, ignition, parking Child and pet tracking
