Madeline Aufseeser, senior analyst at research firm Aite Group, said that what makes this unique is that there are lots of features that come with the account.
"It's just a further indication that pre-paid (cards) have gone mainstream," she said.
Wal-Mart and American Express said that more features will be added to Bluebird in the first quarter of 2013. These features will include more options to deposit money and check-writing capabilities.
Bluebird will be available next week at www.bluebird.com and in more than 4,000 Walmart stores.
