ABSTRACT:
A computer-assisted method includes hardware, software and telecommunications components that cooperatively achieve the technical effect of an improved electronic purchasing 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.
