Abstract
A set of multiple prepaid calling cards that are associated with a single account is disclosed. A predetermined amount of minutes is associated with the set of cards. Cards within the set can be used simultaneously and extract minutes from the account in predetermined increments. Each card can use the same Personal Identification Number (PIN) or each card can have its own unique PIN. In some instances, any card in the set can recharge the account, (i.e., add more minutes to the account), or in some embodiments, only a control card can add minutes to the account.
