Mobile banking is a service provided by a bank or other financial institution that allows its customers to conduct financial transactions remotely using a mobile device such as a smartphone or tablet. Unlike related internet banking it uses software, commonly called an app, provided by the financial institution for this purpose. Mobile banking is usually available 24 hours a day.

Transactions through mobile banking depend on the features provided by the mobile banking app and typically include account balance and latest transaction lists, electronic bill payments, remote check deposits, P2P payments and fund transfers between the customer's or another's accounts. Some amps enable copies of statements to be downloaded and sometimes printed at the customer's premises..
