Abstract

A method for establishing account controls for a transaction account through specially configured personal identification numbers includes: storing, in an account profile, an account identifier, standard personal identification number (PIN), and blocking PIN; receiving a first authorization request for a first payment transaction including the account identifier, a merchant identifier, and the blocking PIN; inserting the merchant identifier into the account profile; receiving a second authorization request for a second payment transaction including the account identifier and the merchant identifier; and transmitting an authorization response in response to the second authorization request including a response code indicating decline of the second payment transaction.
