Grim irony alert: You know those new smart chips on your credit card? They've actually
triggered a virtual crime wave. Hackers and identity thieves, in a rush to exploit the old magnetic swipe cards while they still can, stole an estimated $4 billion in 2016 — a new record.
The smart chips are expected to prevent fraud in the long term, but banks are already thinking of the next big defensive maneuver: A digital update to World War II cipher technology that will replace that three-digit code on the back of your card.
According to new patent filings, the U.K. bank Barclays plans to deploy a new kind of ultra-secure bank card that will use a tiny keypad and digital display on the card itself. The bank card will also incorporate an encryption system similar to that used by famous wartime Enigma machines, which encoded messages by generating constantly changing ciphers using pseudo-random numbers. https://www.livescience.com/57335-spy-tech-could-make-secure-bank-cards.html
