In an exemplary embodiment, a method for leveraging a payment token comprising a non-confidential number (i.e., “cellcard number”), such as a phone number associated with a user's portable computing device (“PCD”), to effect purchase transactions against one of possibly a plurality of value accounts associated with the non-confidential number comprises presenting a cellcard number for purchase of goods, requesting that a value account associated with the cellcard number be debited and, before debiting the value account and completing the purchase transaction, transmitting a request for authorization of the transaction to the user's PCD. |
