One Step IAP

The basic payment interface with AppCoins Wallet is done using an URI (interface) that any Android App can call. That URI defines the basic information needed for a payment: amount, app package, developer wallet,...

That URI follows the EIP681, with small changes. To differentiate those changes from the original standard, it's called EIP681A, where the "A" stands for AppCoins changes.

The Android developer can build the URI manually or can use a SDK to make it easier.
