Startup Idea : Localization social shopping app

I have an idea to create an app for improving social shopping experience in the real life. For example, localization with social features app used in different malls. The app enable shoppers scan QR codes on the items to save information (styles, prices, location etc), store information on in-app shopping list, find out other interested shoppers to share BOGO or other group-buying discounts, find out shortest shopping route according to the saved item locations, create meetup/hangout event for bored shoppers like the husbands who feel boring when the wife is shopping, get broadcasting events and info in the mall.etc.
