- Add your card to the app and accept the terms of use for digital wallets to enable instant contactless payments.
- Confirm your device with two-factor authentication, whether it's a password, biometrics, or a code via SMS, improving user control.
- Keep your banking app updated to avoid crashes or incompatibilities when integrating with recent digital wallets.
- Validate the activation at physical or virtual ATMs, testing with small amounts before entrusting large transactions to digital wallets.
- Activate notifications and alerts to track spending in real time and quickly notice misuse in your digital wallets.
- Request NFC unlocking in the app before your first payment; the feature isn't always enabled by default.
- Check if your bank has set a limit for contactless payments and adjust it according to your usual purchasing habits.
- Keep your password recovery information safe; authentication failures will temporarily block the use of digital wallets.
- Avoid installing applications from unofficial sources, as this increases the chances of integration failures and the risk of fraud.
- If your card expires, replace it immediately in the apps so you don't lose access to your digital wallets until your new physical card arrives.
