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
