QR Scanner ( Working Title)

The Jelly Bean guidelines for Android, plus the wonderful holo stylings was my starting point.
What I've tried to do here is a ultra clean UI. Custom icons have been used throughout, also Ive created a grid in illustrator to recreate the same QR icon for the business card section.

Hey guys, what do you think of each one of the created business cards having this styling. Could something like that be coded?

P.S If you know who this is for, please don't type it on here:)

Hope you are having a good one:)

Update: Just got a email from " " they love this first screen. Now going to begin designing the other 4.
