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
• communicate batteries to power power from the
over distances of the chip’s field generated by
several meters circuitry, resist the reader
interference and • without having an
circumvent a lack active transmitter
of power from the to transfer the
reader signal due information stored
to long 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
