RFID is a technology that uses radio waves to identify objects electronically. It consists of tags that carry data, readers that can interrogate the tags, and software. Common applications include access control, asset tracking, supply chain management, and payment systems like Paywave. A survey found that respondents thought RFID could be applied to inventory control, logistics, library management, and healthcare. Further development is needed in medical and library uses. While RFID provides benefits over barcodes like storing more data, costs remain higher and standards are still being developed.

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 reader
meters interference and • without having an
circumvent a lack of active transmitter to
power from the reader transfer the
signal due to long information stored
distance.
• They are different from
active tags in that they
only transmit data at
the time a response is
received

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
