Error 190 Datafono | How to fix it

October 13, 2025 Freddy Error Fix 0

To resolve Error 190 Datafono, first, check the specific error description provided by the terminal’s system for details on why the transaction failed.

🧐 What is “Error 190” on a datáfono

  • The “Error 190” (or “Causa 190”) generally means “tarjeta denegada” — the card issuer (bank of the customer) declined the transaction without giving a specific reason.

  • Some possible underlying causes include:

    1. Insufficient funds in the customer’s account.

    2. Credit limit exceeded.

    3. Bank‑imposed restrictions or blocks (for example, the card isn’t permitted for that merchant category or type of transaction).

    4. A technical or connectivity issue (network error / datĂĄfono failing to communicate correctly with bank servers).

🔧 What you can try to fix / workaround

If you’re seeing this error and you’re the merchant (or helping the customer), these are steps that often help:

Step

What to do / What to check

1. Ask customer to check their card/accountThey should see if they have enough balance, whether they’ve hit their credit limit, or if there are any blocks on their card (by contacting their bank).
2. Retry the transactionSometimes transient issues (bank server busy, network glitch) cause declines. Trying again might succeed.
3. Try another cardIf they have another card (or another bank), try with that. If that works, it could indicate problem is with the first card.
4. Check datĂĄfono connectivityEnsure the POS terminal has good network/internet connection. Restarting the device might help.
5. Check merchant bank / processor statusPerhaps the acquiring bank or payment processor has issues. Contact their support.
6. Confirm datáfono setup / configurationSometimes certain merchant categories aren’t allowed, or limits are imposed on transactions. If so, settings may need to be adjusted.
7. Update software / firmware (if applicable)If the terminal has updates pending, fixing them might help resolve hidden bugs.

If the error code appears on a computer instead of a physical terminal, it may point to invalid entries left from an incorrect or failed software installation or uninstallation.
