European automobile maker, Renault, used RFID cards to make the AutoRAI Trade Show in Amsterdam a little more interactive. This is probably the first application that I've seen where an RFID card is linked to a person's Facebook profile so that they could instantly 'Like' a car with the simple swipe of the card.
The process looks pretty simple in the video. People who attended the show were given a free RFID equipped card. While the attendees perused Renault's line of vehicles they could swipe the card at the special kiosk to post information about the car to Facebook account and with their friends.
This goes beyond using a QR code to drive someone to a Facebook page. The kiosk provides the attendee with information about the car and they don't have to do anything beyond a card swipe to link it on Facebook. On the other hand with QR the person would still have click to 'Like' the brand but that still doesn't share much with their friends.
Bringing the offline experience online is something that most brands are struggling with. I applaud Renault for their innovative use of RFID.
