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