RFID Tag Sensor Using Smart Attendance System

RFID tags:

Now, three different kinds of RFID tags are commercially available.

1) Passive tags

2) Active tags

3) Semi-passive tags

These passive tags do not have any power supply. They used to get their power from the incoming radio waves from the Readers.

While active tags have a power source for their internal circuitries. And for sending the response to the reader also, it uses its own power supply.

In the case of semi-passive tags, they have a power supply for internal circuitries,...

Active RFID Tracking Web Application Trilateration Demo

http://www.ns-tech.co.uk/active-rfid-tracking-system/

Active RFID people / asset tracking system video showing an attempt at using trilateration to determine the unknown position of tag using the known position of 3 readers, and signal strengths to them.

Large orange spots indicate positions of readers.

The tag was first placed in the centre, then moved to the top left, top right, bottom right, bottom left, top left, then back to the centre.

As can be seen the code needs...

PhilaU MSID: Tilt-Activated RFID Reader Demo

A raw video demo of Team WON's second project for Interactive Prototyping, Fall 2012. The RFID module only reads the tag when it is tilted more than 45 degrees off the vertical axis. If worn on the forearm, this device will only read nearby RFID tags when in the handshaking position.

Dual-Purpose RFID Security Management System : DigInfo

DigInfo - http://movie.diginfo.tv

Hitachi has developed a dual-purpose RFID security management system. The system can be used as a personnel-tracking system or as a building or area access control system. The system utilizes active RFID tags equipped with infrared receivers. Each tag features a unique ID and via infrared transmission is capable of transmitting positional data. This makes it possible to both identify individuals as well as determine their location.
