3. Types of RFID Tags
Passive Tags
Active Tags
Semi-passive Tags
•Use a battery •Contain built-in •Derive their power
•communicate over batteries to power from the field
distances of several the chip’s generated by the
meters circuitry, resist 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

5. RFID
• RFID = Radio Frequency Identification
• Electronic labeling and wireless identification of
objects using radio frequency
• Tag carries with its information
o a serial number
o Model number
o 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

6. RFID components
• A basic RFID system consists of these components:
o 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

7. 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
o Passive
o Semi-passive
o Active

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