Can I get an F10 chargeback on an online order?

You should not, since F10 is a card-present code. If one arrives on an ecommerce sale, point that out in your response and provide your card-not-present evidence, because the code itself is misapplied.

Does a signature alone beat an F10 dispute?

No. Amex wants proof the card was physically captured, meaning a swipe, dip, tap, or manual imprint. A signature without any capture record usually will not carry the representment.

Reason code F10: Missing Imprint

Amex files F10 when a cardmember denies making a card-present charge and the merchant never captured a card imprint, chip read, or magnetic swipe. In practice it targets keyed-in transactions where the physical card was supposedly present but nothing proves it ever touched the terminal.

Why F10 chargebacks happen

A cashier manually keyed the card number because the chip or stripe would not read, leaving no electronic capture record.
A fraudster read card details over the phone or from a photo and the staff processed it as a card-present sale.
The terminal fell back to voice authorization or offline mode and no imprint was taken as backup.
A mobile or pop-up retail setup used keyed entry as its normal workflow instead of a proper chip reader.

How to fight a F10 chargeback

Produce the electronic record showing the card was actually swiped, dipped, or tapped, including the POS entry-mode indicator.
Submit a legible copy of the manual imprint if one was taken at the time of sale.
Provide the signed receipt tying the cardmember to the transaction, plus any CCTV or delivery evidence for the goods.
If the sale was actually card-not-present, say so and reframe the response around your CNP evidence, since F10 does not fit that channel.

How to prevent F10 chargebacks

Ban keyed entry for card-present sales unless staff also take a manual imprint as a fallback.
Replace or repair terminals that frequently fail to read chips, since fallback transactions are where F10 losses concentrate.
Train staff to request a different payment method rather than keying a card that will not read.
Make sure your POS transmits the correct entry-mode data so legitimate chip reads are not misreported as keyed.
