What is a transaction audit trail?
Transaction audit trails provide a detailed, chronological record of every action to ensure financial accuracy, security and compliance. By tracking payments from initiation to completion, audit trails support fraud investigation, performance monitoring, SLA validation, customer dispute resolution and regulatory compliance through irrefutable proof of transaction history. When the payment switch is the only audit trail, a single breach or failure can leave financial institutions and processors without compliant data, increasing exposure to fraud losses, downtime, penalties and legal risk.
