Semi-passive RFID Tags - AutoID | Passive Tags | Active Tags

Types of RFID Tags

 

RFID Tags come in three basic varieties: passive, active, or semi-passive or battery-assisted. RFID Tags and Readers are available in a range of different frequencies with 125kHz, 13.56MHz, 868MHz and 915MHz being the most common frequencies.

Passive RFID Tags:  A Passive RF Tag requires no internal power source and generates no RF signals itself. Passive RF Tags are powered by readers when they are in range. They inherit...

Advantages and disadvantages of active RFID tags | Oprfid.com

An active RFID tag is one in which battery power is used to supply power to the electronics. This enables greater distances to be achieved as the tag is not dependent upon the received power to provide a reflected signal, and the control and processing circuits can be more sophisticated as in the case of the...

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...

What is RFID Tag Reader?

Radio-frequency identification (RFID) utilizes electromagnetic fields to automatically detect and track tags attached to products. The tags store electronically stored information. Passive tags gather energy from a close-by RFID reader's interrogating radio waves. Active tags comprise of a local power source and may operate hundreds of meters from the RFID reader.

How does it work?

Unlike a barcode, it is not required for the tag to be within the sight of the reader, so it could be embedded in the tracked object. RFID systems encompass three elements - RFID tag, RFID reader and an antenna. RFID tags...

RFID - Simple English Wikipedia, the free encyclopedia

Radio-frequency identification (RFID) is a technology to record the presence of an object using radio signals. It is used for inventory control or timing sporting events. RFID is not a replacement for the barcoding , but a complement for distant reading of codes. The technology is used for automatically identifying a person, a package or an item. To do this, it relies on RFID tags. These are small transponders (combined radio receiver and transmitter ) that will...
