Hmmm, I read about it, and it sounds good, but I’m always doubtful when I hear about something that is “going to change the way Americans do business”. Then again, it isn’t as if we have always used credit cards for payments either (ask your grandparents). Remember those rectangular pieces of paper called checks? For those unfamiliar with Card Case, it allows a smartphone user to pay by simply giving the clerk their name, no need to take your phone out of your pocket. The phone must be within 100 feet of the checkout point, and your name and photo will appear on the store’s smartphone, so that the clerk can make sure that you match your photo and are, in fact, you. The first roadblock that comes to mind is infrastructure/equipment. I’m not sure how many small businesses are going to want to adopt a new and unfamiliar payment system. I know quite a few neo-luddites that have small businesses and are even today reluctant to fully utilize computer applications beyond spreadsheets and word processors. As time goes on, and smartphones become more and more ubiquitous, there is less likelihood of resistance. It also helps that there are no set-up fees and a low cost per transaction, which should help alleviate business concerns over adopting new expenses along with new technology. I suspect that a lot of people would like to be able to walk into a local coffee shop and just say the modern day equivalent of “put it on my tab.” In fact, just a paragraph ago, I was doubtful myself, but the more I think about it, the more I like it and think it has a decent shot at long term success. I know I would be willing to give it a try.
