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
• 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

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
