Target Shoppers: Chase Limits Use of Debit Cards JPMorgan Chase reacts to data breach 3 days before Xmas By Neal Colgrass, Newser Staff Posted Dec 22, 2013 3:05 PM CST Updated Dec 22, 2013 3:30 PM CST 10 comments Comments In this Jan. 18, 2008 file photo, a customer signs his credit card receipt at a Target store in Tallahassee, Fla. (AP Photo/Phil Coale, File) (Newser) – Still planning to shop at Target after its cache of debit and credit cards was hacked? Hold on: JPMorgan Chase has limited its debit-card customers to $100 in withdrawals and $300 in total purchases daily at Target stores, NBC News reports. That only applies to roughly 2 million Chase accounts—about 10% of the bank's customers—and credit cards aren't restricted. Plus, the bank says that customers needing more than $100 in cash can drop by a Chase branch to pick up a temporary card. But still—three days before Christmas. "We realize this could not have happened at a more inconvenient time with the holiday season upon us," said the bank. "It’s unfortunate that criminals are active during a time of giving and generosity." Chase didn't say how long the restrictions would last, and promised to ship new debit cards in the next few weeks to everyone whose card was breached. It all started this week when Target said that up to 40 million debit and credit cards had been hacked; now, those card numbers are selling on the black market for $20 to $100.
