Ant International has introduced iris authentication technology in its smart payment glasses, called Alipay+ GlassPay. This new feature enhances security by using over 260 biometric feature points to verify users' identities, which makes it more resistant to spoofing compared to other biometric methods like voice, face, or fingerprint recognition. The technology incorporates AI and advanced liveness detection to thwart fraud attempts involving photos or masks. Xiaomi and Meizu are the first manufacturers to partner with Ant International to integrate payment functionalities into these smart glasses. The glasses aim to streamline the shopping experience, allowing users to hail rides and transition smoothly from trying on products in-store to making instant purchases online. This development represents a significant step in the evolution of contactless payment methods, leveraging biometric security to enhance user convenience and safety.
