The US Fair Credit Billing Act (FCBA) and Electronic Fund Transfer Act (EFTA) limit liability to $50 for unauthorized charges if reported promptly, with 85% of debit disputes resolved per CFPB's 2025 report.

UK users benefit from Payment Services Regulations 2017, offering up to 13 months to dispute and full refunds for unauthorized transactions.

Unauthorized	Transaction without your permission/PIN/signature	Stranger used lost card	Bank direct (60 days US)	Fast resolution; limited to $50 liability
Fraudulent	Theft/identity theft	Card skimmed online	FTC report + chargeback	Strong protections; may need police report / Slower if criminal probe
Billing Error	Wrong amount/merchant mistake	Double charge or overcharge	Bank letter	Quick fix; no fraud stigma / Merchant disputes possible

Bank disputes are fastest (10-20 days); chargebacks offer stronger recourse (up to 120 days).
