Citibank is introducing a biometric mobile app that combines banking, wealth management and money movement features on a single biometrically-secured application. Developed by Citi FinTech, the app was tested with 2500 clients over five months to improve its design and prioritize development, adding new features over a series of two-week development intervals. It was developed using an open architecture incorporating portable APIs, enabling it be modified in real time and customized to different client needs and markets. Initially designed in mind for US Citigold clients, the app offers users the selection of five authentication methods, including fingerprint, voice, facial recognition, PIN and password. Once logged in, users can conduct global transfers to linked current accounts using just an account number, along with buy and sell equities, ETFs and mutual funds. Citibank will also provide Citigold clients with the ability to open a new brokerage account via the app.
