RFID technology allows wireless identification of objects using radio waves. An RFID system consists of RFID tags attached to objects, readers that can identify tags, and software to process tag data. Tags contain information like serial numbers that is transmitted to readers when in range. Common applications include access control, asset tracking, supply chain management and electronic toll collection. A survey found respondents saw potential RFID applications in inventory control, document management, security, and library management. Further development opportunities exist in medical and library uses of RFID. While bringing convenience, RFID has higher costs than barcodes 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 from
• communicate over batteries to power the the field generated by the
distances of several chip’s circuitry, resist 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

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
