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:
-
Insufficient funds in the customer’s account.
-
Credit limit exceeded.
-
Bank‑imposed restrictions or blocks (for example, the card isn’t permitted for that merchant category or type of transaction).
-
A technical or connectivity issue (network error / datáfono 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/account | They 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 transaction | Sometimes transient issues (bank server busy, network glitch) cause declines. Trying again might succeed. |
| 3. Try another card | If they have another card (or another bank), try with that. If that works, it could indicate problem is with the first card. |
| 4. Check datáfono connectivity | Ensure the POS terminal has good network/internet connection. Restarting the device might help. |
| 5. Check merchant bank / processor status | Perhaps the acquiring bank or payment processor has issues. Contact their support. |
| 6. Confirm datáfono setup / configuration | Sometimes 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.
