Grant access to your transaction history
For the Littlebit app to function properly and calculate savings based on your card payments, it is necessary to grant access to your card transaction history on your bank account.
Do not worry - you are not granting access to your funds, only to information about when and how much you paid by card. This allows the app to calculate how much should be saved into Bitcoin.
This access:
- Does not allow sending payments, it only enables viewing transaction history
- Is time-limited to 90 days - after this period, the app will ask you to renew your consent
- Is required to complete registration - without it, you cannot proceed

Select instant login
Click the QR code, which will redirect you to your Smart klíč app.

Confirm the login in the Smart Klíč app
In the Smart klíč app, confirm the login by clicking “Confirm.” By doing so, you grant access to your card transaction information, allowing the app to save into Bitcoin based on your spending.
That's it!
Your bank account has been successfully connected to the Littlebit app. Now just click “Continue” and you can start saving into Bitcoin.
What if an error message appears?
If an error message appears after this step, we recommend checking your connected accounts in the Littlebit app (Settings → My bank accounts) to see whether the account was added despite the error message. This can sometimes happen due to a weaker signal or a slower response between the app and internet banking.
If you can see the account, it means the connection was successful and everything is working correctly. If you do not see the added account, please try the following steps:
- Close the Littlebit and Smart Klíč apps
- Make sure you have a stable and fast internet connection
- Restart your phone and repeat the process following the same steps
