Project topic: RFID Name: Wang ZhuoYu Student ID: 15251616 The document discusses RFID (Radio Frequency Identification) technology. It defines RFID as electronic labeling and wireless identification of objects using radio frequency. RFID tags carry information like a serial number and transmit this to a compatible reader when passing through its field. The document describes different types of RFID tags - active tags with batteries, semi-passive tags with batteries to power the chip, and passive tags that derive power from the reader's field. It also outlines common RFID frequencies and their read ranges and data speeds. Finally, the document lists example applications of RFID and compares it to competitive technologies in different application segments

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. 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
