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

15.  Positive
CONCLUSION
• 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
