After last week's data theft at Target stores, experts say we should expect hackers to keep hunting credit card information.
They say U.S. credit and debit cards rely on an easy–to–copy magnetic strip on the back of the card. That strip stores account information. Most other countries, instead, have digital chips in their cards that store personal data, and generate a unique code for each transaction.
Because the U.S. uses this older technology, experts say hackers have a field day in the U.S.
The older, square–card swiping machines that are common at checkouts are hard to hack, since they do not go through the internet.
But, many retailers are updating to internet–based payment systems which in turn makes it easier for criminals to steal identities.
