transaction system. In various embodiments of the invention, at least one master
account is established for a client. A pool of limited use account identifiers
or secondary account identifiers, that are separate and distinct from the master
account, is associated with the master account by a purchasing system or account
management system. Each of the limited use account identifiers may be used by the
client to purchase items from merchants.
