This document discusses RFID (radio frequency identification) technology, its components, types of tags, and applications. It provides details on passive, semi-passive, and active tags and their read ranges. Common applications mentioned include credit cards, transportation payment systems, toll collection, access control, and supply chain management. The document also summarizes an online survey of possible RFID applications and its results. Further development opportunities in medical and library uses are noted, along with positives and negatives of the technology.

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
