This process of information discovery enables banks to create and target new products and services more accurately and profitably than with conventional "shotgun" marketing approaches. The bank can also link the data warehouse to retail delivery systems to sell tailored products and services at any point of customer contact, whether teller station, customer service desk, telephone service center, or other channel. For example, a bank marketing debit cards can identify and target affluent homeowners with a demonstrated preference for convenience and electronic purchasing, flagging these highly qualified candidates to branch and telephone center personnel who can pitch them on the new service. …
