“By working with Wink to bring their functionality to our Android payment devices, the point-of-sale becomes more than a payment terminal — it becomes an identity-enabled commerce platform. This isn’t just a feature, it’s a fundamental shift representing the future of checkout, one that prioritizes security, speed, and personalization.”“PAX has long set the standard for secure, high-performance payment terminals. Together, we’re pairing their trusted hardware with Wink’s multimodal biometric identity platform to deliver a new era of frictionless, identity-powered payments.”
