That's in the final scope for sure, part of the mission to make is scalable. You can also consider it as a "third part" App that can be integrated on the Busy platform. We are discussing with @bitspace with their bitgate project (decentralized exchange based on Bitshares/Graphene, that can allow fiat to crypto conversion/trading), i'm also in contact with a company in HK that may help us to manage credit card payment as well as offering a Steem Debit Card product to our users. This is probably not gonna happen before the end of 2017 though
