Radio-frequency identification (RFID)
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves. Active tags have a local power source such as battery and may operate at hundreds of meters from the RFID reader. Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object....

What is RFID? How RFID works? RFID Explained in Detail
In this video, RFID (Radio Frequency Identification) Technology is explained by MAC Packaging.
So, in this video, what is RFID, what is inside this RFID system, how RFID works, and application of RFID have been explained.
What is RFID?
RFID is technology which works on radio frequency and it is used for the auto-identification for the different object.
The RFID system mainly consists of two parts.
1) RFID Reader or Interrogator
2) RFID Tags
In this RFID system, this RFID reader...

Radio-frequency identification (RFID)
An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.
Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized...

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,...

IDSense: A Human Object Interaction Detection System Based on Passive UHF RFID
Link to publication page: http://www.disneyresearch.com/publication/idsense-a-human-object-interaction-detection-system-based-on-passive-uhf-rfid/
In order to enable unobtrusive human object interaction detection, we propose a minimalistic approach to instrumenting everyday objects with passive (i.e. battery-free) UHF RFID tags. By measuring the changes in the physical layer of the communication channel between the RFID tag and reader (such as RSSI, RF phase, and read rate) we are able to...

CAEN RFID - Embedded UHF RFID readers presentation
UHF RFID technology allows to read and write information on devices, named tags or transponders, placed on objects for their identification. Read/write operations can occur without line-of-sight, at longer distance and faster speed compared to other passive technologies, thus allowing a cheaper and more efficient process automation.CAEN RFID is a leading company in Automatic Identification (AutoId). It has focused its activities in the Radiofrequency Identification (RFID) in the Ultra High...
