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

4. RFID COMPONENTS
• A basic RFID system consists of these components:
• A programmable RFID tag/inlay for storing
item data;
• 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 Semi-passive Tags Passive Tags
• Use a battery • Contain built-in • Derive their power from
• communicate over batteries to power the the field generated by
distances of several chip’s circuitry, resist the reader
meters interference and • without having an active
circumvent a lack of transmitter to transfer the
power from the information stored
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

7. APPLICATIONS
• Credit Cards with RFID (Paywave function)

13. 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
