Mobile phones have increasingly become tools that consumers use for banking, payments, budgeting, and shopping. Given the rapid pace of change in the area of mobile finance, the Federal Reserve Board began conducting annual surveys of consumers' use of mobile financial services in 2011. The series examines trends in the adoption and use of mobile banking, payments, and shopping behavior and how the evolution of mobile financial services affects consumers' interaction with financial institutions.This report presents findings from the latest survey, fielded in November 2015, which focused on consumers' use of mobile technology to access financial services and make financial decisions. Where applicable, the findings from the current survey are also compared with the findings from previous surveys. Topics include consumer access to bank services using mobile phones ("mobile banking"), consumer payment for goods and services using mobile phones ("mobile payments"), mobile security, and consumer financial management and shopping decisions facilitated by the use of mobile phones. Details about the survey, its methodology, and limitations can be found in the body of the report and in a methodological appendix.
