Good For Their Competitors

From the Chicago Tribune: In the wake of a massive data breach, Target Corp suffered reduced customer traffic over one of the busiest shopping weekends of the year, the Wall Street Journal reported.
The number of transactions at Target fell 3 to 4 percent compared with last year's final weekend before Christmas, while, transactions at other retailers were strong, the Journal said, citing estimates by retail consultancy Customer Growth Partners LLC.
Target said on Thursday that hackers had stolen data from as many as 40 million credit and debit cards of shoppers who visited its stores during the first three weeks of the holiday season.
At least 2 million shoppers who used bank debit cards at Target stores during its recent data breach are facing lower limits on how much cash they can take out of teller machines and spend at stores.  http://www.chicagotribune.com/business/sns-rt-us-target-sales-20131222,0,4427782.story
Today, when working at Wal-Mart, I saw several credit/debit cards declined and many of those people also shopped at Target.
So, it seems like even a threat of fraud, some banks shut down some people's credit/debit cards.
And these people were not very happy, actually, very pissed off, especially if they could not buy what they wanted.
