RFID credit cards = bad idea - Journal of Omnifarious

07:54 am - RFID credit cards = bad idea

Previous Entry Share Next Entry

There might be interesting applications of RFID technology that don't destroy privacy and aren't horribly insecure. Sadly, the people behind RFID don't seem to be interesting in figuring that out. My recommendation is to stay away from anything that mentions RFID at all.

The newest idea is to have credit cards where each card is identified by an embedded RFID chip. This is very insecure as the chips do not require a cryptographically secure challenge/response exchange in order to function. This makes it very easy to clone your card.

Here is a more detailed article by jwz on why RFID credit cards are a bad idea.

Please spread this information around a lot. A lot of people will lack the knowledge and/or analytical skills to see why this is true. So, a lot of 'bad feeling' needs to be generated about the technology to discourage its use and avoid the rather plausible adoption scenario discussed at the end of the article.

Simply put, if RFID credit cards are widely adopted, we will all end up paying for the extra fraud.

The RFID thing is actually much less sophisticated than a smart card. Smart cards are, in general, a better technology.

Is what you're talking about like the smart chip on the Target card?

What does it do? Does it let you just wave the card at something to use it? If that's what it does, then that's what I'm talking about.
