A digital wallet (also known as an e-wallet) allows users to make electronic commerce transactions quickly and securely. A digital wallet functions much like a physical wallet. The digital wallet was first conceived as a method of storing various forms of electronic money (e-cash), but with little popularity of such e-cash services, the digital wallet has evolved into a service that provides internet users with a convenient way to store and use online shopping information.
