Our partners also participated in the preparation of an agreement concerning payroll loans, a banking product that currently concentrates the focus on new demands in Brazil. Retained by C6 Bank, the official consumer protection agency and the Judiciary, an agreement was reached to provide heightened security to banking operations.
