Mobile wallet

A digital wallet, also known as an e-wallet or mobile wallet, is an electronic device, online service, or software program that allows one party to make electronic transactions with another party by exchanging digital currency units for goods and services. This can include purchasing items either online or at the point of sale in a brick-and-mortar store, either using a smartphone or other mobile device to make a mobile payment or (for online buying only) using a laptop or other personal computer. Money can be deposited in the digital wallet prior to any such transactions; alternatively, an individual's bank account can be linked to the digital wallet. Users may also have their driver's license, health card, loyalty card(s) and other ID documents stored within the wallet. The credentials can be passed to a merchant's terminal wirelessly via near field communication (NFC).
