This document discusses RFID (Radio Frequency Identification) and its applications. It begins by explaining what RFID is and its basic components, including RFID tags, readers, and antennas. It then describes the three main types of RFID tags: active, semi-passive, and passive tags. Several applications of RFID are presented across different frequency ranges, including credit cards, transportation cards, electronic toll collection, and access control. An online survey about RFID applications is described that was targeted towards SMEs. Potential future developments and a concluding video are also mentioned.

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
