Abstract
The present invention is associated with a computerized system that takes a subsequence of a credit card number, in particular the suffix (or last n digits), and transaction data associated with the cardholder. For each subsequence of the credit card number, a set of data may be used in order to uniquely identify the cardholder. The identification of the cardholder may be performed in a particular search space that is composed of all possible credit card numbers and includes the transaction data associated with the cardholder. In an exemplary embodiment, the computerized system is used to promote engagements between individual cardholders and merchants by effectuating marketing actions in combination with commercial transactions when products or subscriptions are purchased.
