American ExpressF30Fraud

EMV Counterfeit

The card member says a counterfeit copy of their chip card was used, and the charge was not processed with the chip.

Why it happens

  • The terminal could not read chips and the card was swiped.
  • The chip was bypassed and the stripe was used instead.

What to send to fight it

  1. Terminal records showing the chip was read.
  2. Proof the terminal was chip-enabled at the time of the charge.
  3. The authorization record for the charge.

How to prevent it

  • Use chip-enabled terminals for every in-person sale.
  • Avoid falling back to swipe when a chip card is presented.
