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 from the field

• They are different
from active tags in
that they only
transmit data at the
time a response is
received

13. 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
