The evolution of consumer payment methods continues to unfold, decisively reshaping payments around the world. In order to simplify the payment process, the evolution of payment methods has accelerated; for example, a few European countries have doubled the limits for payments without PIN confirmation, and certain services, such as Google Pay and Apple Pay, have completely abolished limits for transactions without providing a PIN. Despite providing convenience, mobile payments also yield a multitude of payment security issues. The possible risks and inconveniences associated with mobile payment applications are analyzed in this paper based on a survey of 500 respondents. To mitigate these risks and inconveniences, an extension of the existing vulnerable payment protocol is described to complete secure Google Pay transactions using strong authentication methods. The proposed payment authentication protocol also allows users who have phones without NFC to authorize payment transactions on their smartphones.
