Conclusion

4. 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

5. 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

6. 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

7. Types of RFID Tags
Active Tags
• Use a battery
• communicate over
distances of several
meters
Semi-passive Tags
• Contain built-in
batteries to power
the chip’s circuitry,
resist interference
and circumvent a
lack of power from
the reader signal
due to long
distance.
• They are different
from active tags in
that they only
transmit data at the
time a response is
received
Passive Tags
• Derive their power
from the field
generated by the
reader
• without having an
active transmitter to
transfer the
information stored

17. 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
