Merchant disputes

Review a chip liability-shift dispute

Check the terminal, card-entry and authorization records with your processor before asserting a liability shift.

Records to compare

  • Transaction and terminal identifiers
  • Card-entry method and fallback status
  • Authorization result and relevant network data
  • Reason code and processor assessment

Check the conclusion

The presence of a chip on the card is not enough to establish the result for a particular transaction. Use the processor’s assessment and the applicable rule.

Prepare the response

Use the response guide to connect each statement to a record. Check the evidence and follow the deadline and submission requirements in the actual dispute.
