Mobile Payment App Design

This is what a business in United States was looking for in their app design

I need the design done for an app that facilitates mobile payments called "Kiosko" - we have a confirmed logo that I will upload as well as a basic wireframe to work from.
The app is initially for small to medium-sized businesses that wish to process credit cards in their store via a mobile-phone.
I would like to see designs that use the logo (although I would like a different font) which has a lime green / gray color scheme.
The final design should communicate security, ease of use, convenience etc.
This is targeted to small and medium business owners - it will act as a credit card front end for them, but also as a business management tool as you will see from the wireframe pages. I want it to look clean, secure and modern, and have a great UX in the design. Read more
