The latest technology is turning into a vital element in financial business. This paper presents a proposed system called Wi-Fi Security Card (WCS) based on the very common and growing problem of electronic transaction fraud in the countries of India. To solve such problems, we have proposed a novel secure payment method known as Wi-Fi Security Card (WCS). In this paper, we also compared the WCS system to another existing system called Dropped Card Detection (DCD) and Microcontroller and Sensors (MAS). The main advancement of our system over the existing system is that WCS can also prevent fraudulent transactions. Nowadays, security issues in e-payments are usually more demanding than current security issues on the internet. Our findings may enable e-transaction providers to extend their secure payment systems by increasing their protection as necessary for appropriate financial services.
