RFID Radio frequency identification ppt Presentation on RFID

2. What is RFID?

3. What is RFID?
 RFID stands for Radio-Frequency Identification. The acronym refers to
small electronic devices that consist of a small chip and an antenna. The chip
typically is capable of carrying 2,000 bytes of data or less.
 The RFID device serves the same purpose as a bar code or a magnetic strip
on the back of a credit card or ATM card; it provides a unique identifier for
that object. And, just as a bar code or magnetic strip must be scanned to get
the information, the RFID device must be scanned to retrieve the identifying
information.

4. RFID systems consist of three basic
components:
 A tag (also called a transponder),
 An interrogator (a reader or a
read/write device)and
 A controller (a host).

5. How Does RFID Work?
3 Components
 Transceiver – Tag Reader
 Transponder – RFID tag
 Antenna

6. RFID tags
Tag is a device used to transmit information such as a serial
number to the reader in a contact less manner.
Classified as :
1. Passive –
2. Active -
3. Semi-passive –
4. from reader

7. Types of Tags
Passive Tags
 No battery
 Low cost
Active Tags
 On-board transceiver
 Battery – must be replaced
 Longer range
 High cost
Read Only
factory programmed
usually chipless
Read / Write
on-board memory
can save data
can change ID
higher cost

8. There are some common tag

9. Frequency Ranges
Low – 100-500 kHz
 short range, low data rate, cost, & power
medium range and data rate
 Intermediate – 10-16 MHz
High – 850-950 MHz & 2.4-5.8GHz
 large range, high cost, high data rate
 needs line of sight

10. Frequencies of operation
Low frequency
 30-300 kHz
 Tags need to be closer to the reader
 Poor discrimination
High frequency/radio frequency
 3-30 MHz
 Tags can be read from relatively greater
 distances
 Tags can hold more information
Ultra high frequency/microwave
 >300 MHz
 Longest range
 More interference

11. Common RFID Uses:
 Goods management and tracking
 Person and animal tracking
 Contactless payments
 Travel documents
 Barcodes and security tags
 Healthcare data management
 Timing

12. How RFID works in textile

13. How RFID works in textile
 RFID (Radio Frequency Identification) is the wireless use of
electromagnetic fields to transfer data through tags, these tags carry
electronically stored information and are attached to objects/textiles in
order to identify and track them automatically.
 An RFID system is composed by tags (or transponders) that carry the
data, a reader (or interrogator) and its associated antenna

14. How RFID works in textile
 1. The reader transmits a low-power radio signal through its
antenna; this signal is received by the tag (via its own antenna) to
power an integrated circuit (chip).
2. The tag uses the energy it gets from the signal when it enters the
radio field and will briefly converse with the reader to verify,
control and exchange data.
3. Once the data is received by the reader, it is then sent to a
controlling computer for processing and management.

15. Advantages of using RFID in Apparel Industry
 Shopping Redefined
 Operational Enhancements = Customer Delight
 Better Inventory Accuracy:
 Reduction in Cycle Count Time
 Reduced Inventory Carrying Costs:
 Reduced Receiving Time:
 Improved Conversion Rate.
 Increased Sales:
 Prevention of counterfeiting:
 Theft prevention:
 Data Analytics and strategic decisions:
