As for a timetable? Unfortunately, there isn't any -- that's partly dependent on retailers upgrading their gear. However, there's certainly an incentive to offer improvements relatively soon. Although the US was very late to chip-and-PIN payments, it's already the largest market. Even a modest speed-up could drastically reduce checkout times, helping businesses handle more customers. And of course, it'd encourage the use of chip cards -- you might be more likely to lean on yours if it helps you return home that much sooner.
