Can I deposit cash into my One account?

No. At this time we do not have cash deposits available but we understand it is important so we are working on ways to make this possible. We will be sure to let everyone know if/when it is supported in the future. 

In the meantime, you can fund your account by connecting it to an external account, via direct deposit, or by using p2p services like PayPal, Venmo, CashApp, etc.
