RFID HF Tag (Transponder)
An RFID tag is the most important link in any RFID system. It has the ability to store information relating to the specific item to which they are attached, rewrite again without any requirement for contact or line of sight. Data within a tag may provide identification for an item, proof of ownership, original storage location, loan status and history.
RFID Tag consists of an integrated circuit and an antenna combined to form a transponder. RFID tags collect the energy to operate from a Radio Frequency (RF)...

What is a RFID-Tag ?
A RFID-tag is a microelectronic circuit with transmit- and receive-antenna, with a control-unit and a data- and energy-memory. These circuits exist in several types of housings, for example as stick-label, button, chip-card, stick, bracelet, screw or badge. The housing is hermetically sealed and are very robust and resistant against shock, ...

RFID Tags: Active, Semi-passive, and Passive - Barcoding, Inc.
There are three basic types of RFID tags; active, semi-passive, and passive. Active and semi-passive tags use internal batteries in order to power their internal circuits. Active tags also use their battery to send radio waves to a RFID reader, whereas semi-passive tags rely on the reader to supply power for its broadcasting. Both active and semi-passive tags are most commonly used for large-scale applications that need to be read over greater distances. Because of this, they typically broadcast high frequencies from 850 to 950 MHz and can be read from over 100 feet away.
In contrast, passive RFID tags rely solely on the...

Introduction: Radio frequency identification (RFID) can be traced back to the late 1940's work on using RF modulated backscatter for communications [1]. Fig. 1 illustrates the operation of a modern passive RFID system which includes an RFID reader and an RFID tag, composed of an antenna and an integrated circuit chip. The reader signal alternates between a continuous wave (CW) and modulated transmissions. The tag sends data during...

Definition of RFID Tags
RFID tags are a type of tracking system that uses smart barcodes in order to identify items. RFID is short for "radio frequency identification," and as such, RFID tags utilize radio frequency technology. These radio waves transmit data from the tag to a reader, which then transmits the information to an RFID computer program. RFID tags are frequently used for merchandise,...
