Brian Tilzer, vice president of e-commerce and business development for Staples.com, will keynote the Mobile Commerce Workshop at the Internet Retailer Conference & Exhibition June 5-8 in Chicago.

Staples, which was ranked No. 13 in the Internet Retailer Mobile Commerce Top 300 last year, redesigned its app for iPhone and Android.

“This is a complete revamp of our app; we focused on the biggest pain points of shopping. We believe this app will become the ultimate shopping companion for our small business customers,” said Brian Tilzer at the time of the redesign.

As part of the app redesign, Staples added mobile check-ins. The check-ins are similar to those conducted on popular mobile social apps such as shopkick and foursquare. A Staples customer opens the app on an iPhone when near or in a Staples store, and the app, through the iPhone’s GPS technology, senses her location. The app then displays a special offer that can be used in that store.
