Chargeback

A chargeback is the reversal of a card payment initiated by the player's issuing bank after a dispute — the funds are pulled back from the operator, who also pays a dispute fee and takes a mark against their processing record.

Gambling attracts a specific chargeback profile. Genuine fraud (stolen cards) exists, but the sector's signature problem is friendly fraud: a player deposits, loses, then disputes the charge as "unauthorized" or "services not received". Regret-driven disputes make gambling one of the highest-chargeback verticals in card processing.

The stakes go beyond individual losses:

• Scheme monitoring programs — Visa and Mastercard place merchants exceeding chargeback thresholds (around 0.9–1% of transactions) into remediation programs, with fines and, ultimately, loss of processing;
• PSP relationships — high dispute rates raise fees or end contracts.

Defense combines strong KYC (proving who transacted), 3-D Secure authentication to shift liability to the issuer, clear billing descriptors, complete evidence packages for representment (login logs, gameplay records, prior undisputed deposits), and velocity controls in the cashier.

Why it matters: chargebacks threaten the thing an operator can least afford to lose — the ability to accept cards at all. Dispute-rate monitoring and evidence automation belong in platform operations, not in a monthly finance surprise.
