Digital payment applications such as Phone Pe, Google Pay, Paytm, and Razor pay serve as vital components of financial operations in India because of the rise in digital transaction use. The quick convenience of these mobile payment networks creates security gaps that detect users to phishing schemes and malware threats whereas Subscriber Identity Module (SIM) swap frauds and illegal access attempts also occur. The paper examines security features used by these applications while assessing potential weak points along with reviewing existing protection protocols which combine biometric access, two-step verification, encrypted Unified Payments Interface (UPI) protocol and artificial intelligence fraud prevention technologies. Our research examines both emerging blockchain solutions and behavioural biometrics technology although their applications in this field. The research paper provides useful suggestions to improve mobile payment security along with strengthened user protection features.
