How the NSA Spies on International Bank Transactions

``The classified documents show that the intelligence agency has several means of accessing the internal data traffic of the Society for Worldwide Interbank Financial Telecommunication (SWIFT), a cooperative used by more than 8,000 banks worldwide for their international transactions. The NSA specifically targets other institutes on an individual basis. Furthermore, the agency apparently has in-depth knowledge of the internal processes of credit card companies like Visa and MasterCard. What's more, even new, alternative currencies, as well as presumably anonymous means of payment like the Internet currency Bitcoin, rank among the targets of the American spies.''
