Number of software-based facial recognition to secure payments will exceed 1.4 billion globally by 2025, from just 671 million in 2020. This rapid growth of 120% demonstrates how widespread facial recognition has become. Fingerprint sensors will feature on 93% of biometrically equipped smartphones in 2025. Voice recognition for payments is also growing, but will struggle to grow beyond this, due to concerns around robustness. Vendors are recommended to adopt a multi-method biometric strategy, which encompasses facial recognition, fingerprints, voice and behavioural indicators.
