I often reminisce about times I spent with my grandmother. She passed away when I was only nine years old, but fortunately left me with a host of memories that I cherish. How I loved our trips to Walden Bookstore in the Hickory Ridge Mall whenever she'd visit us in my hometown of Memphis. We'd pick out a book or two and then return home to read them together. I often wonder what she would think about my family's book shopping and reading habits today. Online bookstores, e-readers, and audiobooks downloaded or streamed onto mobile phones would be completely foreign to her as the technology behind these was not even around during her lifetime! How could she ever have known how the world of books would evolve?

And this brings me to the notion of future-proofing payments. Mobile payments just might be the hottest topic when payment professionals get together to discuss the future of payments. It makes sense to think that maybe one day our mobile phones will replace our debit and credit cards and maybe even cash. But to date, the mobile phone has not done for cards and cash what it has done for mp3 players, digital cameras, and portable navigation devices, to list just a few things. Perhaps we need more time for mobile phones to transform payments—or could it be that payments as we know them today will be made over by a technology or device that is not yet widely available or even conceived? Is it possible that the primary payment methods we use today can withstand the test of time and remain our primary methods for many more years? Thinking about my grandmother and books, maybe future-proofing payments is a losing proposition and we should be nimble, ready to adapt to whatever changes come our way.

Join me for the Atlanta Fed's Retail Payments Risk Forum's latest Talk About Payments webinar on Thursday, June 28, from 1 to 2 p.m. (ET), when I will explore the future of mobile payments at the point of sale by first considering the debit card's long rise to prominence. Participation in the webinar is complimentary, but you must register in advance. After completing registration, you will receive a confirmation email with all the log-in and toll-free call-in information.
