SYSTEM AND METHOD FOR USING AN ACCOUNT SEQUENCE IDENTIFIER

摘要

Embodiments of the invention provide for facilitating a transaction using a communication device associated with a user. Certain embodiments allow for provisioning a communication device for use with an enhanced primary account identifier. The enhanced primary account identifier includes a primary account identifier (PAI) and a primary account identifier sequence number (PSI). The PSI is unique to the communication device and may be de-provisioned if the communication device is lost or stolen. A replacement communication device may be provisioned for use with a newly gemerated unique PSI without having to generate a new PAI.
