Meet the SALT card: a credit card sized gadget that lets you lock and unlock your phone more conveniently. The SALT card fits in your wallet and pairs with your phone through the SALT app to unlock your phone when it is within 10 feet of the card. Not only you don’t have to provide a password to unlock your phone, you don’t have to worry about locking it either. As soon as you move away from your phone, it automatically locks. You also have the option to restrict access to certain apps.
