Humanmark is a robust solution designed to thwart bots at checkout, employing secure phone hardware to ensure genuine transactions. By tagging products with 'humanmark-required,' businesses can designate specific items for added protection against automated purchases. When customers attempt to buy these tagged items, the Humanmark mobile app facilitates verification through biometrics or a passcode, ensuring an authentication process that is both secure and impervious to spoofing. The integration of Flow allows for seamless automation of payment capture or order cancellation based on successful verification. Importantly, Humanmark ensures complete privacy by not collecting any customer data. Compatible with all payment methods and requiring no code alterations for implementation, Humanmark offers a streamlined and effective approach to securing online transactions.
