There are plenty of “smart wallets” on the market. Not too many of them are actually that smart. The Cashew Smart Wallet is a handy tool that restricts access to your cards only to you. It has a fingerprint reader and can store up to 20 fingerprints, so you can share access with others.
The wallet also has Bluetooth, so it connects to your phone to alert you when you are about to leave it behind. You can also rely on other Cashew users to find your lost wallet. This smart wallet is currently on Indiegogo.
