#cash is as secure as any bank service.

Payments can only be made from a customers own mobile phone.

In addition, all payments are PIN verified.

At registration time, a customer chooses thier PIN.

At transaction time the customer is called and asked to enter their PIN to verify the payment.

Effectively, this is the same Device & PIN type security we use all the time for payments.

The device is the phone and the PIN is a secret known only to the customer.
