"The U.S. currently accounts for 47% of global credit and debit card fraud even though it generates only 27% of the total volume of purchases and cash". You really should not insist that the method used in much of the rest of the world, where fraud is 50% lower, is less secure. Because it really isn't.
Though I'm sure if you ever manage to switch, you will make sure to render your implementation completely flawed and useless, starting with idiotic "chip and signature" payments.
Or not. Maybe they'll just go to the library, or bookstore, or amazon.fr, or fnac.fr, or any other place where they can already find this.
The activity sensors probably senses whether the device user is active or not. Now does it mean physical activity, or actually using the device, I don't know.
The bada OS has a variety of sensors, including accelerometers, tilt, weather, proximity and activity.

That's because of the way you do it. Every single of your nuclear plants is most probably completely different from all the others, maintenance is also probably done by many different companies... every new plant is built like it was the first one you ever built, and every plant is maintained like it was the only one you had, so you never make economies of scale (but each politician who builds a plant gets to please a friend's company, yay).
NB: I'm just guessing for Ontario, based on how things are often done in North America and observations from an uncle whose job is to check the safety of nuclear plants.
Well, it has been standardised for a long time. Decimal separator is either a comma or a period (with a comma being recommended) and the thousands separator is either nothing or a space.
