The Windows Phone 8 Wallet app is pretty exceptional, allowing other apps on the phone to add deals directly to the hub.
As can be seen from the screen shot, developers will be able to add a logo, notes, barcodes and other features.
Unfortunately the API will not allow developers to add co-ordinates, which I think means Microsoft missed a trick which would have allowed local deals to be automatically surfaced.
