Virtual accounts having alphanumeric identifiers different from an alphanumeric identifier of a financial account are linked to the financial account. Financial transactions performed in relation to the virtual accounts result in changing the current value of the financial account. The virtual accounts themselves do not have a current value apart from a current value of the financial account to which the virtual accounts are linked. Performance of the financial transactions in relation to the virtual accounts does not expose the alphanumeric identifier of the financial account that would otherwise be exposed if the financial transactions were performed in relation to the financial account. A given financial account is also linked to another financial account. Performance of a financial transaction in relation to this given virtual account thus results in changing the current value of one of the financial accounts to which it is linked.
