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 Semi-passive Tags Passive Tags
• Use a battery • Contain built-in • Derive their power
• communicate over batteries to power the from the field
distances of several chip’s circuitry, resist generated by the
meters interference and reader
circumvent a lack of • without having an
power from the reader active transmitter to

distance. information stored
• They are different from
active tags in that they
only transmit data at
the time a response is
received

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
