Yes, there have been several expose' about
RFID credit or debit cards. The RFID is often
visible if you really look closely. These can
be scanned by hackers with briefcase size scanners.
If someone sends me RFID card, I'm going to either
punch it with a sheet metal punch, or drill with
a cordless drill. The foil pouches, might work.
So you'll destroy the far more secure option to continue with the
massively insecure option that led to the huge data breach at Target.
Yeah, that level of ignorance is about your speed.
A magnetic stripe card contains the card holder's name, the credit
card number, the expiration date, and the credit verification value
(CVV). Grab that information (which is childishly easy to do with
magstrip cards) and the card can then be cloned and used anywhere.
That's why hackers target US credit cards and US retail operations,
because US credit card companies have continued to use these insecure
Infosecurity magazine, about the vastly more secure RFID credit cards:
There are two primary security measures that credit companies use to
secure information on RFID credit cards: generating a unique
transaction number each time the card is read by a scanner and
restricting the distance that the card can be read to between one and
“There are only three pieces of information that are captured by the
RFID terminal: card number, expiration date, and a control number that
is generated per transaction by the chip based on the information that
the RFID terminals sends to the card. It’s a unique number and it
changes every time. If you were to capture the control number and try
to use that information two minutes from now, it wouldn’t be viable”,
The RFID reader does not capture the name, address, or other personal
information that is included on a credit card with a magnetic strip,
1. The magnetic stripe is the huge security hole on credit cards.
Cards that combine an RFID chip and a magnetic stripe have enhanced
security due to the unique CVV for each transaction. The most secure
cards are RFID only, no magnetic stripe.
2. The RFID can only be scanned from a distance of 1-4 inches.
3. The RFID generates a new, unique CVV to validate each transaction.
Cloning the card won't work, because a cloned card will only have the
single CVV that is printed on the card and contained within the
magnetic stripe - and that can only be used once.
So yeah, stick to your highly-insecure magnetic stripe, because you're
afraid of RFID. Idiot. Your card is more at risk using the old
technology than it will be with the new.

I prefer NEITHER.
As I mentioned earlier there is also a holographic feature on the front side of cards, been there for 20 years.
Holo is far less subject to the wear of a mag-stripe, and it cannot be breached via wireless detection means. It's time to exploit holo's full potential.

Counterfeiting standard holograms is child's play, which is why

Yes, they can be made more secure, but then the cost per hologram goes
from pennies to dollars, which limits their use on a wide scale.
In the video, the guy got the credit card number and expiration number
and cloned a new card. He did not get the security code, because a valid
security code is not included in the scanned information. If the
security code is required, as it probably is for all on-line purchases,
the credit card number is useless. For point-of-sale terminals - which
was used in the video - a security number is seldom (ever?) required
(would be punched in manually), so the cloned card can be used.
With the European chip system (EMV - Europay, MasterCard, Visa),
scanning the card gives you information that is encoded, changes every
time, and can only be used once. It is completely different from what is
on a mag-strip, so you can't clone it to mag-strip. (I don't think you
could clone it to a chip and use that once either.)
EMV is coming to the US. After 10-1-15 fraudulent charges from a
mag-stripe reader will be the responsibility of the merchant, not the
credit card company. After that date using a mag-card should be rather
This isn't email, it's usenet.
Have to cover the RFID antenna area, on both
sides of the card. And probably the edges,
too. So no RF energy gets to the antenna.
You foil tape your chip if you want. I'm going
to use my hole punch and take it right out.
You can try it, but as the RFID operates at a very high frequency, the signal
could travel through the edge of the card where there is no foil.
What is wrong with the hammer? It even works on passports and leaves no visible
signs of tampering.
Don't think this is right. If it were a high frequency, they wouldn't
need a multi-loop antenna a third the size of the credit card. Given
the shape antenna, no matter the frequency, any edge radiation will be
miniscule. AFAIK, all credit cars use 13.56MHz.
That sounds like an invitation for a free colonoscopy.
