In today’s digital age, security is of utmost importance, especially when it comes to online transactions. One effective way to enhance the security of your e-commerce app is by implementing OTP (One-Time Password) verification on the cart page. This additional layer of security ensures that only the rightful owner of the account can proceed with the cash-on-delivery (COD) payment method. In this blog post, we will discuss the steps to set up OTP verification on before placing order on the COD King app.
