Mobile wallet applications aren't anything novel, but most of the existing ones (like Venmo or Square Cash) all have something in common: they require people to have a bank account or a debit/credit card to use them. That's where Airfox differentiates itself. The app is geared toward "unbanked" users in emerging markets who may not have a credit history, due to lack of resources or because they're generally not fans of banks. Part of how Airfox plans to succeed is by adopting services that are already offered in certain countries. Like in Brazil, for example, which is the first place the app's launching. There, users can put money in the app through a "Boleto," a popular paper-based payment method that can be loaded by depositing cash in ATMs.
