For well-nigh 20 years now, the Motley Fool has been here to help you invest better and smarter, using spot-on analysis and a razor-sharp wit. To celebrate Worldwide Invest Better Day on September 25, we are taking some time to get back to the basics -- of investing, that is. In that spirit, I have rounded up some sweet financial sector stocks that have been showing some real sparkle and promise lately.

Without further ado, let me introduce you to the focus of this particular article: Prepaid financial services provider, Green Dot (NYSE: GDOT).

An alternative to conventional banking
Green Dot has been providing alternative banking products to the unbanked and underbanked for more than 12 years. A little over two years ago, the company went public, and its footprint has been increasing ever since. Its prepaid debit cards are available at more than 50,000 retail locations, serving those who are unable to -- or, choose not to -- avail themselves of traditional bank services such as checking accounts and bank credit or debit cards.

Recently, Green Dot stumbled a bit, losing market share after its second-quarter results paled in comparison to those of competitor NetSpend (NYSE: NTSP), and adjusting its outlook downward. Both companies dropped in value, but Green Dot's price sunk over 60% the day of the announcement.

One analyst at Piper Jaffay, however, saw some sun amid the clouds, noting that Green Dot has some big plans for the upcoming months. Earlier this year, the company penned an agreement with Dollar Tree (NYSE: DLTR), whereby the retailer will host Green Dot's general purpose reloadable debit cards and MoneyPak card reload stations before the end of this year. When the partnership is up and running, Green Dot's reach will jump to about 65,000 locations. Green Dot also has deals with UniRush, a company co-founded by Russell Simmons, to provide the retail version of its prepaid RushCard, as well as student-loan company Sallie Mae.

Meantime, Green Dot had a spot of good news from another major retailer. Not only did it renew its contract with Wal-Mart (NYSE: WMT) to continue providing that store's branded prepaid gift cards, but rival American Express (NYSE: AXP) will no longer offer its own GPR card, Bluebird, at Wal-Mart locations. The credit card giant had been trialing its product to the less tony set for a few months, but the product never caught on -- news that has since given Green Dot's stock a nice lift.

One Fool's take
Though Green Dot did disappoint on analyst's projections, it still produced a 17% year over year increase in revenue, compared to NetSpend's 15% jump. While both companies have seen revenue growth drop a bit over the past few quarters, Green Dot's many irons in the fire should help prop things up going forward. Add to that the fact that the continued wariness of bank customers is driving business for the GPR market, and you've got a recipe for success, reloadable at a major retail outlet near you.
