JPMorgan Chase told customers Saturday that they would be limited to $100 in cash withdrawals and $300 in total purchases per day if they used Chase debit cards at Target during a recent data breach, NBC News reported. The new limit -- normal daily limit for transactions on Chase debit cards is $500, and the normal daily limit for cash withdrawals is generally $200 to $500-- applies to about 2 million customer accounts, Kristin Lemkau, a Chase spokeswoman, told NBC News. It does not apply to Chase credit cards. Target announced earlier this week that as many as 40 million debit and credit cards were compromised during the breach, which the store said began just before Thanksgiving and ended Dec. 15. Eager to repair the public-relations damage Target has apologized and offered a 10 percent discount at its stores this week. Chase did not immediately give a time limit for the restrictions. Lemkau said Chase is issuing new debit cards in the coming weeks to all customers whose cards were put at risk.
