An analysis by Juniper Research found billions of smartphone users will be using facial recognition and other biometric authentication technologies in the coming years to authenticate payments made through smart devices, ZDNet reports. The research found 95% of smartphones globally will have biometric capabilities by 2025, and users’ characteristics will authenticate more than $3 trillion in payment transactions. Lead Analyst Nick Maynard said hardware-based systems will be more secure than software-based facial recognition.
