Duo Account

The anatomy of the account’s dashboard relies on a tab navigation from where you can access to all the functionalities:

  • Movements (categorization & search)
  • Duo Deposit
  • Smart Saving
  • Operations
  • Queries

Duo Deposit

Young couples can set a limit to their Duo Account. Once that limit is overcome, the rest of money will be saved in Duo Deposit generating more profitable interests.

Smart Saving

This service will help users to save the amount necessary for a specific objective (a car, holidays ...) within the time limit they set.
