Making mobile phone transactions easier, reaching the un-banked and eliminating the use of cash and checks are the major challenges for capturing credit card market share, says Joan Kelly. Having a payments transaction-processing infrastructure that is robust and flexible enough to launch new products and reward cardholders is the key to success. "That's part of our whole view of technology: Anticipate the infrastructure you will need and then innovate by putting the pieces together for product development," explains Kelly, the senior-most female technologist at MasterCard Worldwide.

Today, MasterCard is reaping the benefits of a payments transactions processing platform that Kelly, Group Executive of Systems Delivery, Global Technology and Operations at MasterCard, and her team have spent years re-engineering. The results can be seen in new products and technologies launched by MasterCard for both corporate and consumer card holders, apart from the fact that the platform processes approximately 140 million payment transactions on a peak day.
