Target payment card data theft highlights lagging U.S. security

The massive data breach disclosed by retailer Target Corp last week is likely to teach its U.S. customers a painful lesson in payment card security and build support for an anti-fraud technology now sitting on the shelf. For years, U.S. merchants and banks have balked at adopting a well-established system that uses credit and debit cards that store information on computer chips. The technology, ubiquitous in Europe, Canada and elsewhere, makes it harder for thieves to misuse data compared with cards that store data only on magnetic stripes. The delay may prove costly to Target’s U.S. customers.
