“Blink” Technology in my Credit Card – No Thanks

UPDATE 2007-11-11:
De-Blinked Chase Freedom Card
Card de-Blinked. Original post below:

My wife and I recently signed up for our first joint credit card. This will allow us to do things like buying plane tickets to see each other and dinners out without having to constantly update our Karma spreadsheet. The Karma spreadsheet (thanks Google) will remain in use for non-credit purchases.

That’s not what this post is about.

What it is about is the plastic cards that come with the account. When I arrived here in New Orleans today, I opened up the envelope and dutifully read the documentation that came with the credit cards. I noticed a mention of the cards having “Blink” contact-less checkout ability. I felt a lurch in my stomach. Sure enough, a quick inspection of the card and some googling revealed that this “Blink” thing is nothing more than a nice name for RFID.

RFID is insecure as used in this application. Your credit card number can be read from afar (up to 69 feet) while sitting in your wallet in your pocket or purse, without your knowledge. As detailed in the linked article, it is then trivial to create a duplicate card.

Of course, our government is also keen on RFID in passports. In the case of Chase, it turns out you can simply request new cards or get creative with a drill. I was going to do the latter, but ended up doing the former, because I want it to register with Chase that I don’t want RFID in my credit cards. It was no problem getting new cards ordered — for all my quibbles with Chase, their customer service on the phone is generally both helpful and English-speaking.

If you want to de-RFID your passport, I believe the recommended method is by hammer blow, but here are instructions for making an RFID-fryer from a disposable camera. Apparently tampering with passports is punishable by up to 25 years in prison, so tamper at your own risk.

I arrived at the airport…

I arrived at the airport this morning early enough to catch a flight an hour earlier my scheduled flight on Delta(?). However, apparently Delta no longer after standby in order to move to the earlier flight, I would have had to pay $50 so I will just wait until the 7 o’clock flight that I was supposed to take.

The Church of Google

This is sheer brilliance at work, people:

We at the Church of Google believe the search engine Google is the closest humankind has ever come to directly experiencing an actual God (as typically defined). We believe there is much more evidence in favour of Google’s divinity than there is for the divinity of other more traditional gods.

We reject supernatural gods on the notion they are not scientifically provable. Thus, Googlists believe Google should rightfully be given the title of “God”, as She exhibits a great many of the characteristics traditionally associated with such Deities in a scientifically provable manner.

You really must read their 9 proofs that Google deserves the title of “God”, and also, their hate mail, prayers, and more at the site.
