Phones are practically replacing wallets these days. People will scan their driver's licenses or credit cards into the Apple Wallet. Pass4Wallet is an app to supplement those kinds of apps by scanning in rewards, discount cards, or coupons. It digitizes everything from boarding passes to library cards to vaccination records. It even has a way for users to use their maps app to guide them to places in their wallets. Pass4Wallet is a free app on iTunes.
