Next year or so you may be calling for a new card when yours is not accepted. Initially, you can swipe, but once all the readers are upgraded, it may not work as the reader defaults to the chip if it is a chipped card.
Fear of the unknown. People used to fear the automobile too.
This is off the top of my head so my memory could be faulty but... EMV was developed years ago by a consortium of card companies (EuroCard, Master Card, and Visa thus EMV). It was widely accepted in Europe but US banks decided it wasn't worth the extra cost. What the people on this thread are calling RFID is really a variety of wireless systems. Some just provide a fixed number to ID an item. That is usually what it meant by RFID. Others involve a microprocessor and memory but are also wireless. The reader has a coil to supply power to the chip wirelessly. The chip wakes up and can communicate (two-way) with the reader. I don't know if EMV now has a wireless version, but the older implementation had contacts on the card.
Do they actually say that it is "RFID" or is it merely a chipped card (chip and pin)? The latter has been used in the rest of the world for a very long time rather than our primitive magnetic swipe cards? All of the North American CC purveyors are supposed to be switching to chipped cards although they are fighting it and dragging their feet.
I wonder what the outcome may be if you disable the rfid, your number is stolen and a counterfeit card is made with no rfid to validate it like the disabled one that the owner has been using? Liability for the disabled security perhaps?
I'll trade that in exchange for less risk of losing my date by a crook with a walk by RFID scanner in a mall, some where.

Some "active" rfids don't need a battery either - they have an inductive power loop, so are powered by the sensor. Key-fobs are one such application.
If they told everyone exactly how it was secured, it wouldn't be secure any more. "If I told you how it works I'd have to kill you"
Here in Canada we have the "EMV" style chip cards, but they also work as a "pay pass" card. The range on the "pay pass" appears to be well under half an inch from my experience. If tyou don't "tap" perfectly square to the serface of the reader, most often it will not authenticate. The RFID key fob for the keyless entry system at the office is less demanding, but still requires being a lot closer than half an inch from the reader.

:) I should hope not. Finding out can't be so difficult. Knowing there's encryption, for instance, doesn't help to bypass it. But before I'd trust it I'd want to understand the details of how it works so that I could assess whether there are risks.
I don't destroy mine. If someone gets *that* close, we will have a problem.
PS. If you get a new (US) passport it has an RFID chip. Some people recommend taking a hammer to the chip. If you do, and its deemed deliberate you can be charged with destroying government property! So don't admit to it.
Indeed. They can use the chip to find the thief.
Some dude told me they can track exactly how much money you're carrying while walking through the airport. I asked how, and he held up the bill to the light and showed me the strip. I laughed...
Cards with RFID are noticeably thicker, and they don't have the visible contacts.
The range is small, like an inch or less.
You could build a RFID detector, detector. The chip itself is powered by an induced electrical field.
So now the merchant knows you have a tampered with card. Good luck buying high-ticket items with it.
Visa cards issued in the US that are mag-stripe only work outside of US.
I destroy the pins they send, they are only good for cash advances (now).
I have a couple I never even signed. I've never been questioned about it!

Here's one way they can get the pin:
PIN goes with chip. rarely chip is damaged and unable to read, then POS handheld unit requests to swipe the card, print out hard copy for signature and receipt for card holder. I never saw a card without chip has PIN. What is such a big deal? Canada as well as whole world has been using chip and PIN for many years already. Maybe because smart card(chip) is an European invention. In some things, U.S. is far behind...???
