Radio Frequency Identification – is
an automatic identification method, relying
on storing and remotely retrieving data using
devices called RFID tags or transponders
using high frequency Radio waves.
![Page 5: Technical Presentation on RFID](https://reader033.fdocuments.in/reader033/viewer/2022052911/559cf9261a28abda298b45fe/html5/thumbnails/5.jpg)
A Tag is a transponder which receives a radio signal and in response to it sends out a radio signal.
Tag contains an antenna, and a small silicon chip that stores a small amount of data
![Page 6: Technical Presentation on RFID](https://reader033.fdocuments.in/reader033/viewer/2022052911/559cf9261a28abda298b45fe/html5/thumbnails/6.jpg)
Tag is powered by the high power electromagnetic field generated by the antennas – usually in doorways
The field allows the chip/antenna to reflect back an extremely weak signal containing the data

When radio waves from the reader are encountered by a passive RFID tag, the coiled antenna within the tag forms a magnetic field.
The tag draws power from it, energizing the circuits in the tag.
The tag then sends the information encoded in the tag's memory
PASSIVE
![Page 10: Technical Presentation on RFID](https://reader033.fdocuments.in/reader033/viewer/2022052911/559cf9261a28abda298b45fe/html5/thumbnails/10.jpg)
The tag functions without a battery!
They have a useful life of twenty years or more.
Less expensive to manufacture
The tag is much smaller (some tags are the size of a grain of rice).
Almost unlimited applications in consumer goods and other areas.

Very Short Distance◦ The tag can be read only at very short distances,
typically a few feet at most.
◦ This greatly limits the device for certain applications.
Very Long Time◦ The tag remains readable for a very long time, even
after the product to which the tag is attached has been sold and is no longer being tracked
PASSIVE
![Page 12: Technical Presentation on RFID](https://reader033.fdocuments.in/reader033/viewer/2022052911/559cf9261a28abda298b45fe/html5/thumbnails/12.jpg)
An RFID tag is an active tag when it is equipped with a battery that can be used as a partial or complete source of power for the tag's circuitry and antenna.
Some active tags contain replaceable batteries for years of use; others are sealed units.

It can be read at distances of one hundred feet or more, greatly improving the utility of the device

The tag cannot function without battery power, which limits the lifetime of the tag.
More expensive, often costing $20 or more
Physically larger, which may limit applications.
The long-term maintenance costs
Battery outages can result in expensive misreads.

The time factor plays a key role in the process of getting a product from the manufacturer to the point of sale because time is money
RFID technology significantly increases the efficiency of this process chain.
With RFID data are transferred without physical contact.
