📱 Caixa Tem Official App Full Description (collapsed)

The Caixa Tem app makes everyday life easier! You can access Caixa Tem to check your balance, statements, card bill, make payments, transfers, investments, mobile top-ups and more!

To access Caixa Tem and view balances, register your Internet username and password in the "I don’t have a username" option. If you forget your username or password, simply register a new user in the same option.

To perform financial transactions you must have Electronic Signature, which you use to complete payments, transfers, and all financial movements. To register your signature: sign in with your username and password, click the Passwords & Settings icon and the Submit Electronic Signature button. After registering, unlock it at any ATM.

Your security is our priority, so when you perform your first transaction (e.g., a payment), you will be prompted to register the Device — this confirms the device is authorized to perform transactions for an indefinite period or a specified period. To register the device, follow on-screen instructions.

Only for account holders.
