Payment Insights & Benchmarks

Merchants in this MCC should anticipate a nuanced payment landscape, where customer preferences and transaction dynamics play critical roles. Payment acceptance may vary considerably based on the chosen methods and the inherent risks associated with the hospitality sector.

• E-wallets: becoming increasingly popular for their convenience, particularly for frequent travelers.
• Mobile payments: on the rise, especially among younger customers who prefer contactless options.
• Gift cards and vouchers: often used for promotions, but managing deductions and reconciliations is key.

Authentication & security

Enhanced security measures, including 3DS, are commonly employed to mitigate fraud risks.

• Strong Customer Authentication (SCA) may lead to friction in the customer experience, so striking a balance is essential.
• Regularly updating fraud prevention tools is crucial to stay ahead of new threats.

Benchmarks (indicative, not guaranteed)

MDR: typically higher than standard e-commerce, reflecting the risk profile of the hospitality sector.

• Rolling reserves: often required to be higher due to chargeback risks associated with bookings.
• Settlement cycles: can be extended, often exceeding standard 3-5 days.
• Chargeback ratios: often elevated compared to retail averages due to service-related disputes.
• Approval rates: generally lower for card payments, while alternative methods may have better acceptance.

Key metrics to monitor

Decline rates segmented by payment method and customer profile.

• Chargeback volumes and reasons for disputes, particularly focusing on service quality.
• Customer payment preferences over time to identify shifts in behavior.
• Average transaction value and its fluctuation during peak seasons or events.

Risk & Compliance

Merchants under the MCC 3664, often associated with travel and accommodations, must navigate significant risk and compliance challenges. Due to factors like high chargeback rates and the potential for fraud, PSPs and acquirers demand that merchants actively maintain safeguarding practices.

Chargebacks & fraud

Common chargeback reasons include trip cancellations and unauthorized transactions, often leading to a spike in friendly fraud claims.

• Stolen credit card usage for bookings can lead to disputes, especially if customers do not physically show up.
• Mitigation tools effective in this sector include velocity checks, customer verification forms, and fraud detection solutions that analyze booking patterns.

AML/KYC expectations

Comprehensive customer identity verification (IDV) processes, including robust checks against sanctions lists and PEPs, are paramount.

• Source-of-funds verification is essential, particularly for customers making large bookings or deposits.
• Manual review triggers may include frequent cancellations, large upfront payments, or evidence of suspicious travel patterns.

Operational red flags

Lack of transparency regarding booking terms and conditions, especially for cancellation policies, raises concerns for PSPs.

• Use of white-label websites without clear tracing back to legitimate operators can lead to trust issues.
• Traffic sourced from high-risk regions or partnerships with unverified affiliates may prompt additional scrutiny.
• Absence of clear dispute resolution processes or customer support can amplify risk factors in merchant operations.
