We are launching a new app so users can check the stored-value balance of their transit card.
We require the design of square app icon for the iOS app store that conveys that the app is related to their travel card
Key themes to (possibly) be conveyed:
1) public transport
2) a card with monetary value (like a credit card)
3) the app supports multiple agencies, and therefore several different card types
As it's for iOS 7, please check that designs fit and scale using this template: http://appicontemplate.com/ios7
I was originally thinking the icon could look like a card, perhaps with a black stripe (like a credit card, although these cards typically use RFID, not a stripe)
Other thoughts were a card with wheels (to kind of look like a bus), a wallet with a card, or a series of cards all together
I've attached some basic ideas and pictures that show what cards look like, as well as:
I don't have a specific colour scheme, but the app primarily uses black/white/grey with a somewhat "standard" iOS7 look and feel.
