Customers at Macy's this Black Friday, may have needed a little more patience to get through their shopping.

On of one of the busiest shopping days of the year, Macy's stores in Minnesota and nationwide experienced a slowdown for their credit card system.

"It is taking longer than usual to process some credit and gift cards in our stores, but we have added additional associates to the floor are working to resolve the issue as quickly as possible," said Andrea Schwartz, a Macy's media representative for the region including Minnesota, in a statement.

As of about 5:30 p.m. CT, Macy's said the problems were "fully resolved" and blamed the issue on "overcapacity" that caused some transactions to take longer to process.
