Much like everyone else, I'm a part of the 1 million cards activated. My immediate reaction was of course to go purchase something at Walgreens. The experience was easy and once people get the hang of it it will become even faster. However, I question whether there isn't a deal to be had here. Perhaps this is a way for MCX to come to the negotiating table with the card brands in a position of power. If users gravitate towards security and user experience but no merchant accepts it, will Visa and others budge on interchange?
