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 store

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
