While ISIS isn't completely forthcoming on its launch plans, the first two markets it will come to are Salt Lake City, Utah, and Austin, Texas, sometime this summer. Incidentally, Austin, Texas is where we are right this very minute, and we stopped by ISIS's SXSW Interactive booth for a quick demo of the app itself. The app looks simple and fairly elegant, and will also have some built in "deal" functionality which a rep told us is opt-in, and the ability to upload and store loyalty cards into the app for participating merchants.

The ISIS rep reminded us that the demo version they showed us is still in prototype phases, so expect at least minor tweaks and improvements in the final version.
