Yeah, it's odd. Competitors like Venmo rely on not putting the money directly into the recipients bank account until they cash out. So they can make a little interest money off that directly, and more importantly, any transactions that come off of someone's balance are free since they are just moving money around inside their computers.

Given they will have the debit card saved, perhaps Snapchat is thinking it will be much easier to offer products to their users in the future.
