The Mobi wallet is available for Android and iOS and supports up to 15 languages. When downloading the wallet, it will be linked to the mobile number with which you downloaded the app. Users can choose which currency to work with and can convert between 100+ currencies (including silver and gold). Using a private blockchain, Mobi allows users to send funds to any of the 2 billion other smartphone users out there and to any of Twitter’s 319 million users. Users can also request an optional Visa debit card which is linked to their Mobi account and allows them to withdraw cash in any currency at ATMs worldwide or spend their funds at any retail points of sale that support Visa. The debit card automatically deducts funds from customers’ wallet balance.
