Mythbusters guys not allowed to demonstrate what the RFID chips are doing.
That’s interesting.
Interesting.

BUMP!
Good find.
RFID ain’t rocket science. All it is at its heart is using EM radiative power to induce energy into a system, and then the system turns around and gives a coded reply.
That it happens with very low voltages isn’t such a big thing, it’s that things are being put together in volume, repeatability, and with supporting infrastructures. All of those put together make it the powerful solution or scary situation that RFID is.
That’s actually kinda’ scary.
Credit card companies wouldn’t let them... why not?
;^)
Just got my RFID “ORCA Card” yesterday.
It's an all-in-one, self-debiting, self-funding pass card for all public transportation in the Seattle metro area.
I even get an instant online record of every transaction.
If my funding Visa Card suddenly goes nuclear, I'll know where the security breach came from.
I have often wondered why someone couldn’t just capture credit card data from a credit card with a chip; simply by just walking closely to someone.
They would just need the thing that reads the chip in the credit card in their hand.
Of course with all new technology, it's a conspiracy to control our lives. < / s>
Basically, the data (Name, account number, etc.) is not encrypted and it's easy for a third party to query the card without physical contact. They can extract the info while it's still in your wallet.
I remember reading about a case in Europe where someone was able to insert a credit card shaped device into an ATM slot and capture the information of whoever had just used the ATM.
It sounds a little farfetched to me unless the ATM had kept that information in memory which I don’t believe they do.
That’s weak. The credit card companies are content to depend on security through obscurity. Mythbusters or not, the details of how the system works will get into the hands of the bad guys. The card companies will suffer losses as a result, but these are built into the overall business model and will amount to only a few basis points.
What they should do is junk the cards and build a payment system that will run in your mobile handset. To make a payment, you would establish a three-way conversation between your handset, the bank, and the merchant, with the merchant’s POS terminal providing connectivity to your handset via Bluetooth and to the bank over the internet. Everything between your handset and the bank would be encrypted, so that the merchant’s POS would carry it but be unable to read it. To guard against lost or stolen phones, your account details would be stored encrypted in the handset, and you would supply a key to enable the payment process.
“Finally! Someone who understands what absorption modulation is!”
Yes, it is a very deep and dark mystery and only a few are chosen to receive the gift of understanding. Thank God that we are among the chosen few! Remember the sacred blood oath that we took, and do not violate it!
Exactly right. Rather than getting all in a lather over RFID and going nuts with conspiracy theories, do some reading or find a tech-savvy engineer or internet group and you’ll quickly see this technology is about as sinister as a USB drive.
“omeone could stand behind you in line and read your cards in your wallet or purse if they have chips. Very scary indeed. “
Kind of what I guessed.
That part is easy. But the data you have when you are done are strongly encrypted, and not very useful.
If it’s the one I’m thinking of, they set a fake cover over the reader that swiped the card when you did a transaction.
If you want to destroy one, microwave it.
If you want to shield it from being read, wrap it in foil.
If you want to lower your IQ, read the comments on a Youtube video page.

Dumpster Baby has uttered in public the "forbidden RFID words". He must be dealt with, as prescribed by the ancient IEEE scrolls, as written by Ohm, Franklin & Maxwell!

There was a case a couple of years ago in Rhode Island where some Armenians showed up at an all night Stop and Shop. While one of the gang distracted the skeleton staff, the others swapped out the debit card PIN pads at the registers, substituting hacked versions that recorded the card info and PINs. Not long afterward, local banks started getting complaints of unauthorized ATM withdrawals. They noticed that all the hacked cards had been used at the Stop and Shop prior to the unauthorized transactions. And sure enough, the PIN pads were found to be modified.
They reviewed the surveillance videos and briefed the staff to watch for the bad guys, who needed to return periodically to retrieve the recorded card details. They were busted soon after.

“But the data you have when you are done are strongly encrypted, and not very useful.”
Not my area of expertise. It seems like the machines that read them in store could be just as easily be portable however?
The RFID chip in my Pug Gus’ neck is his best friend in a pinch, as well as a guaranteed ticket home if he ever gets lost. Ditto for all five of our (adopted) ferrets...
i carried a PROX-Card ID at work for most of the 90's that would be read while still in my wallet when ever i walked in or out of any door that had a reader...
I have broken Kirchoff’s Law and have no capacity to resist the current opinion of my actions. I will discharge my obligation to do penance and ground myself in humility. I will not impede the standing waves of Freeper opinion and will rectify my behavior.
That has happened here in Canada. The scam involved inserting a card reader into the slot on the ABM and hiding a camera to record the user keying in the PIN. The banks here had all of the ABMs modified to prevent it.
Is that a tin foil wallet?
My new driver's licence has an RFID chip in it, but it came in a sleeve that blocks scanners- the Ministry recommends carrying it in the sleeve. I'm surprised that the credit card issuers aren't doing the same.
Would that be the one where the defence for a speeding ticket is to point out that if the officer knew where you were he couldn't possibly know how fast you were going?
Here in Toronto there were a lot of similar scams, most of which were inside jobs- one member of the ring would get a job as a night attendant at a gas station, and they’d swap out the card reader for the duration of the shift.
They don't.
Just imagine someone walking through a crowd at a subway station, a mall, Disney World, or countless other places, and stealing all your secure info using this $8 device?
But there have been cases of fake ATM machines, that record account #’s, PINS, claim to be “out of money”, and then phone in the data.
Sleeves for credit cards and passports can be purchased here: http://www.idstronghold.com/
No, but it's related. It's not that sophisticated. I constructed it for 1st year students.

I effing warned you.
I have this idea where, instead of using cards, we exchange small pieces of precious metals for goods and/or services.
What is an RFID???? Absorption modulation! Voltage, encryption?
Clueless in Pittsburgh.

I’d tell you but then I’d have to kill you. ;0)
Mostly just some inside engineering jokes.
Don’t worry. The situation is hopeless, but not serious.
