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
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
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
TYPES OF RFID TAGS
Type of RFID TagsActive 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

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
