RFID BLOCKING CARDHOLDER
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.
Our handmade cardholder functions as a shield for payWave cards as it contains aluminium from tetra paks .. This aluminium creates Faraday Cage to prevent RFID wave from hacking your payWave cards.

The Antichrist, The Beast and The Dragon Are Coming... Are We Prepared?
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 a 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...

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...

Readers for UHF RFID Wireless Sensors (Part 6 of 7) Tutorial
Learn more at http://www.phaseivengr.com - the inventors of battery-free wireless RFID sensing. Readers that support UHF RFID sensors are explained in this video. These readers include Intermec (Hand Held and Desktop), Feig OBID, ThingMagic, and custom readers. All of these readers (other than the custom reader) are off the shelf and use firmware developed by the reader manufacturer to read RFID sensor tags. The tags can be battery-free passive RFID sensors, Battery-Assisted Passive (BAP)...
