An internet bank—often referred to as a digital bank, virtual bank, or online-only bank—is a financial institution that conducts its operations exclusively through online platforms, mobile applications, and digital networks rather than maintaining traditional brick-and-mortar physical branch offices for retail customers. By eliminating the massive overhead costs associated with leasing, staffing, and maintaining physical branches, internet banks are typically able to offer customers higher interest rates on savings accounts, lower monthly maintenance fees, and reduced transaction costs. These institutions provide full banking services, including electronic check deposits, bill payments, and loans, backed by standard federal deposit insurance.
