RFID Scan Blockers
« on: February 15, 2016, 12:33:35 AM »
I pay for small items with my standard debit card that uses a RFID chip and we call it Pay-Wave.

should I worry about illegitimate scanners possibly copying my card's chip (no relation) ?

do you guys use this technology much ?

my mate recently lost funds from his account that were not explained ... the bank is investigating.

I've got one of those scanners. They're really easy to buy, not terribly hard to use if u know a few things about setting up chunks of code. However, it's been my experience that in order to use one u need to have the card RIGHT on top of it.

If u are concerned someone is going to stand behind u in the grocery store with one of those in their pocket and lean in and capture ur shit, then get a thin, solid aluminum/metal, card shaped piece cut/made/bought, and put one on each side (inside but on the perimeter edges) on each side and it'll create a shield that won't allow rfid to penetrate, somewhat like a faraday bag. No rfid works thru metal. Well, technically there's some X-rays that can penetrate several inches of metal, but I don't think rfid can get out...

Also there's different types of encoding and protocols that effect what scanners are able to pick it up. For example, my scanner can't read the chip in my passport but can read my metro card, it can't read my keyfob to get into my building but it can read my credit cards.

yeah Chops,


I heard that, or even metal screens of various sized mesh can work as a faraday cage as well--the screen must be metal--not nylon though.


These cards with chips in them were common when I was in France in the late 1980's.


Surprise it only took 30 years for the US to catch up with le Technologie Francaise.

Yeah chops I believe al foil should do it. I know it works on rfid chips in car keys so I dont see why it wouldn't work for cards. Actually I will check it out tomorrow and let u know tomorrow if I get time

Almost all of the Faraday cages I've seen in industry are made of copper mesh.


I'm pretty sure any metal will do, but I do wonder if it needs to be a diamagnetic metal as opposed to paramagnetic or ferric metals.


If diamagnetic is best, the copper, aluminum & silver would be best.
