What This Code Means
“EMV fallback” indicates the chip read did not succeed and the terminal is attempting an alternative (such as swipe) when allowed by the processor/acquirer rules. Some environments restrict fallback to reduce fraud.
Where Users Usually See This Code
- During chip insert transactions
- When the card chip is damaged or dirty
Why This Code Appears
- Chip read failed due to contact issues
- Reader contamination or wear
- Terminal configuration requires fallback after repeated failures
What Typically Happens Next
- Terminal prompts to retry insert or to swipe
- Transaction may be declined if fallback is not permitted
What This Code Is Not
- It is not the same as “declined”
- It is not a batch settlement issue
Troubleshooting Checklist
- □ Retry chip insert and ensure the card remains inserted until completion
- □ Clean the card and reader contacts per vendor guidance
- □ If fallback is blocked, request another payment method
Notes And Edge Cases
Fallback rules are compliance-sensitive; do not override processor settings.
