The Skim Reaper – a Credit Card Skimmer Detector

If you have heard about credit card skimmers, you probably know the advice to tug on a credit-card scanner before using it. That’s not really that effective against more and more of the scanners, as they are getting smaller, and more easily hidden within or on top of real scanners in such a way that a sharp tug just won’t reveal them any more. Enter the Skim Reaper, a scanner that works instead by checking for multiple voltage spikes such as those caused by a hidden reader.

We have partnered with law enforcement agencies to comprehensively characterize skimmers, with the goal of designing and delivering strong tools to reduce this kind of crime. As a result, we created the Skim Reaper™, which specifically targets overlay and deep-insert skimmers.

A better  brief explanation can be found at Ars Technica, one of the finest geek sites on the web.

SkimReaper is aimed specifically at overlays and inserts. It uses a card-shaped sensor with a printed circuit that, when powered, can detect the voltage spikes created by coming in contact with magnetic reader heads. If it detects two or more, there’s a skimmer in play.

While I have found no information yet on how to build your own nor how to buy your own Skim Reaper to keep yourself safe, I am sure that both a DIY guide and a pre-made Reaper purchase option will happen before too long.

The World is Warming

Earth is warming. Slowly, and not noticeably so to most people, but nevertheless it is happening. More ways to see this are available in this Washington Post titled “Red hot planet: This summer’s punishing and historic heat in 7 maps and charts” and published Friday. I expect some people will read this and have something of a “OK, the planet is getting warmer, but we aren’t causing it to happen.” I really can’t do any more to convince those people than post Skeptoid’s “The Simple Proof of Man-Made Global Warming” for their reading or listening pleasure.

You might think that carbon is carbon, and that if we find there’s more CO2 in the atmosphere, its source can’t easily be proven. But chemistry is a bit more complicated than that; there are different kinds of carbon, as there are of most elements. They’re called isotopes. One isotope of carbon is carbon-14.

The science involved isn’t really that difficult to understand. The knowledge that we are doing this and possibly making the planet uninhabitable for ourselves isn’t hard to gain. But getting some people to believe it sure seems tough. As denialists become fewer in the United States, we are hopefully moving to a period where we can make progress on reducing our effect on the planet, but we still have a way to go before we become part of the solution. But the general population is catching up to the scientific consensus, I think, which is a good thing.

The most frustrating thing, though, is that some folks knew 40 years ago, and rather than work to prevent this and make sure everyone knew about the potential harm, they kept it silent and made sure to profit from the ignorance of others. I know that this is just how big corporations work, but it still sucks. And I realize they did do research on the topic, but they could have brought humanity’s knowledge of the problem much further along than it is know if they had made a big deal of it in the 70s. That’s just me being a hopeless romantic, though.

They found that the company’s knowledge of climate change dates back to July 1977, when its senior scientist James Black delivered a sobering message on the topic. “In the first place, there is general scientific agreement that the most likely manner in which mankind is influencing the global climate is through carbon dioxide release from the burning of fossil fuels,” Black told Exxon’s management committee. A year later he warned Exxon that doubling CO2 gases in the atmosphere would increase average global temperatures by two or three degrees—a number that is consistent with the scientific consensus today.
