I think the same technology might allow thieves remote use of paywave cards.
> If you have a wireless key fob for a car with a remote keyless system, then you might want to start keeping your keys in a freezer or other Faraday Cage to protect it from high-tech thieves, who can use a $17 power amplifier to break into your vehicle.
> Cars with keyless entry systems are capable of searching for a wireless key fob that is within a couple feet of the vehicle, but car thieves can use a $17 "power amplifier" to boost the key searching capabilities, sometimes up to around 100 meters, and pull off a high-tech car break-in.
> After almost becoming a victim of a high-tech car heist again, Nick Bilton over at The New York Times said he is now keeping the keys to his 2013 Prius in the freezer. There had been a rash of mysterious car break-ins near his Los Angeles address, including three break-ins to his own car; all cars involved had remote keyless systems that come with a wireless key fob which is used to unlock the doors and start the engine instead of using a physical key.
> Recently, he was looking out his window and saw a girl hop off her bike and pull out "a small black device from her backpack. She then reached down, opened the door and climbed into my car." He ran outside and the girl split, but he was curious about the black device she used to open his Prius.
> He called Toyota but got no useful info; the LAPD blew it off and told him that he must have forgotten to lock his car. However, he scored when he found a Toronto Canada Police public safety alert warning about "a spike in theft of Toyota and Lexus SUVs" that left no signs of physical damage at any of the crime scenes.
> Finally, he got answers from Boris Danev, the founder of Switzerland-based 3DB Technologies. The girl most likely used an inexpensive "power amplifier" to break into Bilton's Prius.
> Mr. Danev said that when the teenage girl turned on her device, it amplified the distance that the car can search, which then allowed my car to talk to my key, which happened to be sitting about 50 feet away, on the kitchen counter. And just like that, open sesame.
> "It's a bit like a loudspeaker, so when you say hello over it, people who are 100 meters away can hear the word, ‘hello,' " Mr. Danev said. "You can buy these devices anywhere for under $100." He said some of the lower-range devices cost as little as $17 and can be bought online on sites like eBay, Amazon and Craigslist.
> What's the best way to protect your vehicle if it has a keyless entry system? The best way, Danev told Bilton, is to "put your keys in the freezer, which acts as a Faraday Cage, and won't allow a signal to get in or out."
