If your wallet is full of a bunch of tattered punch cards from your favorite businesses, Front Flip may be the app for you.

Front Flip is a new customer loyalty app that has recently partnered with dozens of Minneapolis businesses. Here's how it works: After downloading the app, it will show you a list of businesses nearby where QR codes will be available to scan. Scan the code to get a virtual scratch-off, and “scratch” the card for the chance to win prizes like half-price appetizers and buy-one-get-one entrees.
