Merchant acquiring in Ireland is dominated by global/fintech acquirers (Stripe, Adyen) alongside traditional banks, operating under EU PSD2 (SCA), PCI DSS and Visa/Mastercard scheme rules. Card-scheme dispute/monitoring regimes — Visa VAMP (full enforcement from 1 October 2025) and Mastercard's Excessive Chargeback Program — pass risk to acquirers, who manage merchant onboarding/underwriting, reserves and high-risk-MCC treatment. EU PSD2 SCA/TRA exemptions interact with these scheme programs. Chargeback rights for Irish cardholders run via Visa/Mastercard scheme procedures (typically 120–180 days).
The cardholder-recourse framework operates through voluntary scheme procedures. The Irish cardholder chargeback framework operates via voluntary Visa and Mastercard scheme procedures in card operating contracts allowing chargebacks for non-delivery and lack of conformity, with filing windows typically 120 to 180 days and a 14-day merchant response window before automatic refund; acquirers apply higher due diligence to high-risk verticals such as travel, gaming, forex, crypto and international e-commerce. This defines cardholder recourse windows and acquirer high-risk underwriting practice in Ireland. Quantitative operational metrics — chargeback ratios by merchant category, acquirer reserve and stress data, and high-risk-MCC volume share — are not evidenced beyond these qualitative scheme-rule descriptions, an acknowledged under-indexed area for the jurisdiction.
Outlook
The merchant-acquiring trajectory is escalating. The October 2025 VAMP enforcement start and the threshold drop from 220 to 150 basis points, combined with Mastercard's Excessive Chargeback Program, raise the compliance and chargeback-management burden on the fintech acquirers that dominate Irish acquiring. High-risk verticals will continue to attract heightened underwriting scrutiny. The principal intelligence gap is quantitative operational depth, which remains under-indexed for Ireland.
Merchant Acquiring & Risk
A reported, but unverified, market-practice signal from Ireland's card-acquiring side concerns gambling merchant category codes. Irish card-issuing banks are reported to have implemented transaction-level blocking of gambling merchant category codes for credit-card payments, following the statutory prohibition on credit-funded gambling that took effect on 5 February 2026; debit cards, e-wallets and bank transfers reportedly remain permitted. This account rests on a single lower-tier consumer-facing source and has not been corroborated against a bank or Central Bank of Ireland primary statement, so it is carried here as a market-practice report pending verification rather than a confirmed supervisory or industry position.
Outlook
This item should be treated as provisional until corroborated by a primary bank or Central Bank source; if confirmed, it would indicate private-sector risk controls running ahead of, and reinforcing, the statutory credit-funded-gambling prohibition.
