Startup Idea: Secure Mobile Payment and Sales Tracking App

Startup idea to develop a secure mobile app enabling sales agents to accept credit and debit card payments, guarantee the security of transactions, track sales, and provide proof of payment to customers.

I work as a sales agent with Makeover Essentials, a cosmetic company. We use direct marketing to inform people about our products and sell them to the public. As of right now we are only able to accept cash. Most people carry credit and debit cards so it presents a problem when you have a person willing to pay for your product but there's only one method of payment available. As of now we don't have any type of software that we can take secure credit and debit payments through. I would like an app that I can download on my phone so that I can take payments in a way that will ensure the customer that it is a secure transaction. I would definitely pay for this type of software because it will garner more sales for me. I'd love for it to have available a way to track sales as well as offer proof of payment for the customer.
