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
