(CNN News) - Target has run into another holiday shopping glitch.
The retailer confirmed on Tuesday that some customers are having problems using their Target gift cards at the cash register.
A spokeswoman tells CNN that "some Target gift cards were not fully activated and apologize for the inconvenience."
Target declined to provide a tally of faulty cards, but said they will honor the problematic cards.
This comes just after target revealed it had been the victim of a massive credit card hack that breached 40 million customer accounts, and stole encrypted pins.
