KYC Automation for High-Volume, Low-Value Transactions – Best Practices?

Curious to hear how firms are handling KYC/KYB for high-volume, low-value transactions, especially in emerging markets. We're looking at scaling operations but the manual review overhead for smaller ticket sizes is becoming a real bottleneck, despite robust initial checks. Are there specific vendors or internal process automations that have proven effective in reducing friction and cost while maintaining AML compliance? Specifically thinking about solutions that can flag suspicious activity without over-escalating routine micro-transactions. Any insights on maintaining a good balance between compliance and operational efficiency would be greatly appreciated. What are the common red flags that your automated systems effectively catch, and what still requires human intervention at scale?
