What is the business model of payments in Payment Pal?

The business model chosen is an online payment platform, ‘PaymentPal’, that allows users to manage an online wallet and using balance and/or linked bank accounts on third-party websites as the payment method. PaymentPal is not only useful for buyers, but it also acts as a wallet for sellers to receive payment.

The implementation of this business model will obviously require the storage of sensitive user and financial information, which therefore makes this system a prime target for malicious attack. The attack surface for this business model is broad and financially rewarding for a malicious third party that exploits vulnerabilities as user’s financial or personal details may be stolen for sale or direct use.
