Reducing card scheme message errors

How INETCO solutions help acquirers avoid declines and penalties due to failed card scheme communications

Reducing card scheme message errors

What is a card scheme message error?

A card scheme message error happens when an acquirer fails to successfully exchange a message with a card network such as Visa, Mastercard or American Express. Merchant advice code (MAC) and response code errors can be triggered due to scheme rule violations (associated with merchant category restrictions, fraud and money laundering), invalid or missing mandatory transaction fields, incorrect field length or data type, wrong message versions (like a wrong ISO 8583 variant) or network connectivity issues. These errors lead to costly unexpected decline rates and card network penalties.

Detect card scheme message errors in real-time

INETCO solutions passively capture in-flight transactions across all cards and payment types. Every message field – including application payload, metadata, response and request timings – is decoded to detect and isolate card scheme message, merchant advice codes (MAC) or tampering in milliseconds, supporting acquirers to resolve errors before they breach the card scheme monitoring thresholds set by card networks, avoiding costly penalty fees.

MONITOR

Monitor the end-to-end payments authorization process in real time, alerting to MAC and response code errors, missing or mismatched field errors, connectivity issues, unexpected declines and recurring retry loops to fix issues before card scheme monitoring thresholds are breached

TROUBLESHOOT

Drill into transaction profiles captured across all card network payment flows to isolate the point of failure by merchant, gateway, switch, network, issuer host, region or card product type and reduce time-to-resolution while preventing repeat incidents

ANALYZE

Strengthen ongoing scheme compliance and evidence-based investigation by analyzing and fixing recurring card patterns before they lead to penalties, customer disruption and disputes around fraudulent or closed accounts (MAC 03), stolen cards (response code 43), lost cards (response code 41), suspected fraud (response code 59), transaction duplicates, repeat submissions and partial completions

Avoid card scheme fines by fixing the real problem, not guessing at the cause

Improve authorization

Increase transaction success rates by identifying and fixing message field errors, unexpected declines and bottlenecks before they cause service disruption

Avoid costly penalties

Gain end-to-end transaction visibility to instantly flag MAC and response code errors, connectivity issues and routing issues – across all card types

Accelerate root-cause analysis

Shorten investigation cycles with transaction-level evidence and end-to-end profiling of every transaction – across every hop of the journey

Increase audit readiness

Provide accurate transaction intelligence and independent transaction audit trails when card scheme penalty investigations or compliance reviews occur
