This app has probably been around for a while but I don't know anyone else who has it so I figured I would share it with all my radio friends this morning. One of my friend who works at a local supermarket told me about it yesterday. I'll be using it because I can't stand having a wallet stuffed with rewards cards.
The app is called the Key Ring app. You download it on your phone and then scan your rewards cards. Once your done all you have to do is go to the app when you are on the checkout line. All of your scanned cards come up. Just select the one you want to use. Then the bar code appears.
One word to the wise. Don't throw out your plastic rewards cards after you scan them. If you get a new phone you might have to scan them again. The Key Ring app works in I Phones and Android Phones.
