1. A method of building a customer database using checks from a variety of different banks comprising:

  • detecting a customer'"'"'s checking account identification number for use as a unique customer identification code;

    entering the unique customer identification code into a processor containing a database that maintains customer records including the customer'"'"'s name and address, the checking account identification number, and customer transactional data over a pre-selected time interval;

    comparing said checking account identification code with said database;

    generating a response with said processor to signal the presence of the customer'"'"'s identification code or the failure to locate the customer'"'"'s identification code;

    creating a new record in said database for that customer'"'"'s identification code in response to a processor response indicating the failure to locate, so that the customer'"'"'s name and address is entered into the record along with the customer'"'"'s transactional data; and

    selecting customers in said database whose last transaction date is prior to a pre-selected interval of inactivity so that that grouping of infrequent customers is available for marketing efforts.
