A year after Groupon acquired Breadcrumb, a point of sale system and iPad app, the deal-of-the-day website has launched the suite of cloud-based iPad and smartphone tools. The free iPad app enables quick-service eateries, salons, spas and retail merchants to maximize revenue.

Groupon has unveiled new versions of the iPhone and Android apps that helped make it a global e-commerce leader.

Executives from Walmart, Facebook and Groupon are among the keynote speakers slated for the Mobile Commerce World three-day conference and expo in June.
