RFID involves the use of small electronic tags that can be attached to or embedded in objects to track them wirelessly using radio waves, with tags containing data that is transmitted to an RFID reader when within range; the basic components of an RFID system include RFID tags containing chips and antennas to transmit data, readers to interrogate tags, and software to process the data; common applications of RFID tags include access control, asset tracking, supply chain management, and electronic toll collection due to benefits like contactless reading and ability to store more data than barcodes.

3. RFID
RFID = Radio Frequency Identification
Electronic labeling and wireless identification of objects using radio
frequency
Tag carries with its information
 a serial number
 Model number
 Color or any other imaginable data
When these tags pass through a field generated by a compatible
reader, they transmit this information back to the reader, thereby
identifying the object

4. RFID COMPONENTS
A basic RFID system consists of these components:
 A programmable RFID tag/inlay for storing item data;
 Consisting of an RFID chip for data storage
 an antenna to facilitate communication with the RFID chip
A reader/antenna system to interrogate the RFID inlay
Application software and a host computer system

5. RFID TAG
The RFID tag consists of an integrated circuit (IC) embedded in a thin film
medium.
Information stored in the memory of the RFID chip is transmitted by the
antenna circuit embedded in the RFID inlay via radio frequencies, to an
RFID reader
3 types
 Passive
 Semi-passive
 Active

6. TYPES OF RFID TAGS
Active Tags Semi-passive Tags Passive Tags
• Use a battery • Contain built-in • Derive their power from
• communicate over batteries to power the the field generated by
distances of several chip’s circuitry, resist the reader
meters interference and • without having an
circumvent a lack of active transmitter to
power from the reader transfer the information
signal due to long stored
distance.
• They are different from
active tags in that they
only transmit data at
the time a response is
received

15. CONCLUSION
Positive
 RFID is a contactless reading technology and can read through other materials
 Hold more data than barcode does
 RFID tags data can be changed or added
 More effective, bring lots of convenience to us
Negative
 Cost is relatively remain high (compare to barcode)
 RFID signals may have problems with some materials
 RFID standards are still being developed
