hi. thanks for joining me today. I'd like
to bring up a topic that a lot of you
may be hearing a lot about in the news
or are concerned about nowadays with
companies getting hacked and data
breaches happening on a daily basis how
do you know that you, yourself are being
protected? we all have these debit and
credit cards which allow us to make
contactless payments, but did you know
that your personal information could
actually be compromised without your
knowledge?
I'm going to demonstrate how this can be
done now. I'm going to use an app which
allows me to read data off of these
cards and show you how easy it is for
somebody to do so. I have the app loaded.
I'm going to zoom in here so that you
can see. I'll start with this card first.
as you can see the number there with
most of my other information there
blotted out, obvious reasons of course.
just like that very easy. so let's try
another card. here we'll use this one and
as you can see that's the information
there and as easy as swiping, as you can,
see has read this card.
now this card reader app is meant for
analysis purposes so potentially if
there's any additional information that's
available that the hackers have figured
out then they can grab that info too. so
here's a list of all of the previous
transactions that's stored on the card
itself.
so let's see what happens if you have a
credit card in your wallet. can this read
through that?
as you can see it was very easy. now
granted that this application is for
analytical purposes and it is not meant
to read from far distances, but any
hacker out there or anyone with some
knowledge can probably rig something up
with one of the development boards out
there such as Raspberry Pi or Arduino
and create something that can read at a
further distance. so what can you do to
protect yourself?
there are several solutions out there
and I will quickly go over them here.
the first one being, buying a wallet that
has capabilities of blocking RF. so in
this case I have a wallet here by
Bastion and it can block those
kind of signals. how these wallets work
is that internally they have a fabric
that's made out of some sort of metallic
mesh and this blocks radio frequencies.
and so these are woven into the wallet
itself. let's try this again with this
wallet.
and as you can see it's not able to read
the card. one thing to note is that you
don't want the really cheap wallets where
only the outside is protected. you need
it so that even between the cards on
this layer.
there's also mesh between that will
protect the card even if the wallet is
open.
and the last solution that I have today
which I will show you is something
called vault card and this is the
package here. and what vault card does is
it itself is a card that has RF
capabilities. so it works similar to your
credit cards or your debit cards that
have that contactless payment. what it
does is it acts like one of those
contactless cards and but instead of
sending actual data it provides
scrambled data to confuse any kind of
card reader out there. if the thief has a
powerful RFID skimming system which can
read cards from far distances the vault
card can actually send out a stronger
signal. and the vault card is also only
one point two millimeters thick so it's
all just slightly larger than a card, a
credit card or a debit card and it
doesn't need any batteries. it's self
powered similar to all your contactless
cards. so what I'm going to demonstrate
next is the vault card in use. what I'm
going to do is place the vault card
underneath my credit card similar to how
it would be positioned in the wallet and
try and read the card.
as you can see it's not able to read it
now if I remove the vault card it should
be able to read this credit card. and
there you go it has read it. now if I try
this again
and one last time but this time what
I'll do is I will remove the vault card
slightly and as it starts to read I will
push the vault card back in and you will
see that I cannot read the card.
and there you go it's not able to read
it.
one thing that potential thieves could
do is they can skim the data off these
cards and actually copy out onto
another blank card and start permitting
purchases or they can use this data that
they've collected and make purchases
online or even sell your credit card
information to somebody else that would
be willing to do that. so there you go a
few ways to protect yourself and your
personal data on your contactless
payment cards using either vault card
and an active solution or some sort of
RFID blocking wallet which is a passive
solution. if you found this video useful
