Professionals have been urging Target and other retailers to upgrade their PoS systems to read debit and credit cards not by their magnetic stripe, but by the chip-based smart card standards already set in the U.K.
This new card security technology is called E.M.V. or Europay-Mastercard-Visa, named after the security technology's first investors. This would beef up the security on cards, since magnetic stripe reader technology has been around since the '60s.
Retailers have been given until October 2015 to upgrade their PoS systems, but many researchers believe that the cost of replacement - $500-$1,000 each - will put most stores past the deadline.
What you can do right now is to replace all of your credit and debit cards. Hackers can't use your information if what they have is out of date.
