Payment Insights & Benchmarks

Merchants operating under this MCC should anticipate unique challenges related to payment acceptance and related costs. Given the nature of transactions associated with customer financial institutions, it’s essential to understand the dynamics of payment processing in this sector.

Payment methods

Cards: often utilized for direct transactions but may experience variable approval based on customer profiles.

• E-wallets: gaining popularity for convenience and speed but can be restricted based on the financial institution’s policies.
• Bank transfers: commonly used, yet they may have longer processing times and higher decline rates.
• Mobile payments: increasing adoption, though security concerns can impact usage.
• Checks: still relevant for certain demographics but are declining in popularity due to processing delays.

Authentication & security

Strong Customer Authentication (SCA) is usually mandatory, enhancing transaction security but possibly affecting approval rates.

• Multi-factor authentication can deter fraud but may increase friction in customer experience.
• Continuous monitoring of transactions is vital to mitigate risks related to account takeover and fraudulent activities.

Benchmarks (indicative, not guaranteed)

MDR: generally higher than standard e-commerce due to inherent risks.

• Rolling reserves: may be applied to manage risk exposure, often set at a percentage of transaction volume.
• Settlement periods: frequently extended beyond typical cycles (7+ days).
• Chargeback ratios: tend to be elevated compared to traditional retail sectors.
• Approval rates: are typically lower for card transactions, whereas bank transfers might see better rates but longer processing times.

Key metrics to monitor

Authorization rates segmented by method and customer profile.

• Chargeback rates differentiated by cause (fraud vs. service issues).
• Customer feedback related to payment methods used.
• Transaction decline reasons aggregated for analysis.
• Patterns in transaction volume during peak periods to identify potential risks.

Risk & Compliance

Merchants under this MCC are closely scrutinized due to elevated financial and reputational risks. PSPs and acquirers typically apply stricter controls, expecting merchants to proactively address fraud, chargebacks, and AML/KYC compliance.

Chargebacks & fraud

High incidence of friendly fraud (“I didn’t authorize this transaction”), where customers dispute legitimate transactions.

• Increased risks of card-not-present fraud and account takeover incidents.
• Mitigation tools include velocity checks, device fingerprinting, and fraud detection algorithms to monitor unusual transaction patterns.

AML/KYC expectations

Strong customer identity verification (IDV) procedures are essential, incorporating sanctions and politically exposed persons (PEP) checks.

• Source-of-funds verification is required, especially for high-value transactions or unusual payment behaviors.
• Manual review triggers include large deposits from new accounts, atypical transaction volumes, or use of anonymous payment methods.

Operational red flags

Lack of transparency regarding ownership and business affiliations, raising concerns about hidden operators.

• Unverified marketing channels or traffic sources that may indicate higher risks.
• Absence of clear consumer protection measures, such as transparent refund policies or dispute resolution processes.
• Inadequate compliance with fraud prevention and responsible lending practices.

• maintain detailed logs of transactions and events to support dispute resolutions and representments

Payment acceptance optimization

implement multiple payment methods (cards, bank transfers, digital wallets) to accommodate diverse customer preferences

Business Scope & Examples

This MCC covers businesses involved in payment transactions initiated at customer financial institutions. Merchants under this category usually provide services related to the transfer, processing, or management of funds in connection with financial transactions. The scope includes businesses that facilitate payments directly linked to bank accounts or financial services.

• Money transfer operators — services like Western Union or MoneyGram; classified differently as they focus on remittance, not traditional banking transactions.
• Peer-to-peer payment apps — platforms facilitating personal payments often not linked directly to traditional banking transactions; assessment needed for classification.

Signals for correct classification
