A computer implemented method of associating commercial activities on an individual comprising acquiring a set of biometric data from an individual at a time of a first activity;

• storing the set of biometric data in a database as set n;
• acquiring a set of biometric data from an individual at second time and storing the second set of biometric data in the database as set n+1;
• using a biometric identification algorithm to determine if set n and set n+1 identify the same individual within a predetermined probability;
• if set n and set n+1 identify the same individual, associating the first activity and the second activity;
• and based on the association between the first activity and the second activity, providing customized advertising or marketing information to the identified individual at the time of the second activity or at the time of a subsequent activity.

A method for profiling an individual based on the individual's commercial activities and using the profile to assist the individual with subsequent activities comprising acquiring a set of biometric data from an individual at a time of a first activity and creating a profile of the individual which does not include private information;

• storing the set of biometric data in a database as set n;
• acquiring a set of biometric data from an individual at second time and storing the second set of biometric data in the database as set n+1;
• using a biometric identification algorithm to determine if set n and set n+1 identify the same individual within a predetermined probability;
• if set n and set n+1 identify the same individual, storing the first activity and the second activity within the profile;
• and using the profile to associate the individual with prior commercial activities at the time of a subsequent commercial activity.
