This document discusses RFID (radio frequency identification) technology, including its components, types of tags, applications, and a survey on potential industries for adoption. It provides an overview of RFID systems consisting of tags, readers, and application software. The main types of tags are passive, semi-passive, and active, which differ in power source and read range. Current applications discussed include credit cards, transportation payment systems, access control, and supply chain/logistics. A survey found the top industries interested in adopting RFID were logistics/supply chain, libraries, and pharmaceutical manufacturing. The document concludes that RFID provides benefits but also has higher costs and standardization issues compared to barcodes.

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
