How biometric authentication boosts UPI security: Key benefits and challenges for digital payments

tech.hindustantimes.com:

As online transactions become a staple of daily life, securing financial information remains critical. The Unified Payments Interface (UPI) has transformed money transfers with its efficiency and ease of use. However, this advancement necessitates strong security measures to safeguard users against threats and fraud.

Biometric authentication verifies an individual's identity using unique physical or behavioural characteristics. This can include fingerprints, iris patterns, facial features, voice, or even typing patterns. This method is more secure than standard passwords or PINs since it offers a customised and secure way of identity verification.

With the rise in UPI transactions, traditional security measures like passwords and PINs are increasingly inadequate. These methods are susceptible to hacking and phishing attacks, making them less reliable for protecting sensitive financial data. Biometric authentication introduces a layer of security that relies on unique biological traits, making unauthorised access more difficult and reducing fraud risks.
