Description
In October 2008, Dr Joel Brenner of National Counterintelligence Executive warned that Chip and PIN credit card readers used at point of sale in Europe had been tampered with either where they were manufactured or while in transit to financial institutions. Credit card information intercepted by the rogue devices was being relayed back to criminals via the mobile phone network.
According to MasterCard, the easiest way to identify devices that have been tampered with is to weigh them, as the rogue devices weigh 4 ounces (110 g) more than the authentic ones because of the addition of hardware-based spy components.

“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
—Ralph Waldo Emerson (1803–1882)
“He hath achieved a maid
That paragons description and wild fame;
One that excels the quirks of blazoning pens.”
—William Shakespeare (1564–1616)
