Some of PayPal's new digital wallet amenities go beyond just payments, but rather reinforce the platform as a one-stop shop for mobile commerce in general.
For example, users will be able to create personal lists for different shopping situations as well as create budgets by purchase amounts and other metrics.
Then there are a lot of other features that carry over from PayPal's browser platform such as being able to switch from one funding source stored in your PayPal account to another seamlessly. Users will also be able to apply different sources of value (i.e. gift cards, loyalty points, etc.) within the same app.
One of the most interesting features in this regard is being able to change the payment source after you've already bought a product in a store. Basically, you can buy something in a store, take it home and decide later how you want to pay for it for a grace period of five to seven days.
