Target has run into another holiday shopping glitch.
The retailer confirmed 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 we apologize for the inconvenience."
Target declined to provide a tally of faulty cards, but said they will honor the problematic cards.
This comes after Target revealed it had been the victim of a massive cred card hack that breached 40 million customer accounts and stole encrypted PINs.
