When purchasing cryptocurrency, debit cards generally offer a smoother experience compared to credit cards. However, there are several common reasons why your card may fail during a transaction:
Common Causes for Failed Transactions
-
Using Someone Else’s Credit Card: Many onramps have security measures that prevent the use of credit cards that don’t match the account holder’s name, ensuring the safety of transactions.
-
Incorrect Billing Information: Providing mismatched billing details (e.g., address, name, zip code) can cause your card to be declined.
-
Insufficient Balance: If your card does not have enough funds to cover the purchase, the transaction will fail.
-
Bank or Card Issuer Restrictions: Your bank or card issuer may decline the transaction or not permit purchases involving cryptocurrency. This is a common issue and can be resolved by contacting your bank directly or trying a different card.
-
Suspicious Activity Flags: If your usage patterns are considered irregular (e.g., using different cards frequently, employing VPNs, or inputting inconsistent country, currency, and nationality combinations), you might be flagged as suspicious, resulting in a declined transaction.
-
Exceeded Platform Buying Limits: You may have reached the maximum buying limit imposed by the onramp or platform you are using, preventing further purchases.
What to Do If Your Card Fails
If your card isn’t working, the best approach is to:
- Check your billing details to make sure they match your bank's records.
- Try using a different card or payment method.
- Contact your bank to confirm there are no restrictions on crypto transactions.
- Review platform limits and make sure you haven’t reached any set purchase thresholds.
Onramper’s Role
