Create better layout for entering/displaying card info

[brarcher]

The layout when adding a card, namely:

and when displaying a card for scanning or reading at a store, namely:

could be improved. They are functional, but could be improved to be more visually appealing and perhaps easier to use. In addition, if the application is to let a user add a thumbnail of the store, namely #86, there currently is no place to put the thumbnail.

There are a number of other applications available on Google Play. Although this application should not be a clone of them, perhaps they could be used as inspiration.

Hello,
As already discussed in issue #113, I suggested if it is possible to show the bar-code first before the card information.
Making this will allow the users to always have the bar-code in view without the need of navigating in the screen to show it completely, especially when the device is in landscape orientation.
What do you think?
