Macy's in San Francisco is testing a new app that alerts shoppers of specific store discounts on their iPhones.

The new app is called Shopkick.

Macy's at Union Square is one of a handful of stores testing the technology.

Here's how it works: Macy's has set up transmitters around the store that send discount alerts every time a shopper walks by an item that's for sale.

It's just a test for now, but if it's a success, it could take off with retailers everywhere.
