The payments industry had quite a decade. As we say goodbye to the first decade of the 21st century, what better time to take a look at the events that have shaken up the payments industry since 2000. Back at the turn of the century MasterCard and Visa were bank-owned associations, knee deep in litigation. Debit cards were growing rapidly and online was still a scary frontier with security concerns and fraud. People weren't paying for anything with a mobile phone and contactless payment was still something only used in exotic locales like Hong Kong.

Last month for the PYMNTS Voice blog, Paying with Plastic author David S. Evans compiled what he thinks to be the greatest developments in the payments business were over the last decade and why. David identified 12 and used the 12 Days of Christmas to count them down. We've compiled the full list here, counting down from #12 to #1, with links to their corresponding full post. We hope you'll let us know if you think David overlooked a particular great development and share your top 12 below.

#11 How the World War on Interchange Fees Transformed the Card Industry

#10 Collateral Damage from the Financial Crisis: Consolidation and Regulation

#9 Shanghai Surprise

#8 The Mag Stripe Lives On

Some of the greatest developments in the last decade were the failure of massive efforts to displace the humble magstripe card. It is also serves as a reminder that innovations in payments have to make people and merchants significantly better off to gain traction. Read the full post here

#7 How the ACH System in the U.S. is Encouraging Electronic Payments Innovation

A major factor in what you might call the greening of the payments industry has been the growth of the Automated Clearing House (ACH) system for directly debiting and crediting depository accounts. Read the full post here

#6 What Has a Bigger Head and Longer Tail? Card Issuing

#4 The New Kid on the Block: PayPal

Starting a new payment system is incredibly difficult. Many try, few succeed. MasterCard and Visa did it in the 1960s. No one did it in the 1970s at least in the US. Sears brilliantly did it with Discover in the 1980s. The 1990s was a miss. For this decade the only company that entered the exclusive club of major payment systems was PayPal.

#3 Debit Takes the Plastic Throne in the U.S.

Mobile illustrates just how this industry can drive progress and really make the world a better place. I also think that it is a harbinger of a revolution that will take place over the next decade. Read the full post here

MasterCard and Visa emerged as publicly traded financial powerhouses after four decades of working for associations of banks. Their transformation marks a radical shift from the past and will most likely define the shape of the payment ecosystem for decades to come. Read the full post here
