Abstract: This invention relates to a novel method of obtaining and using anonymous consumer purchase and demographic data that comprises providing a multi vendor capable instrument, such as a uniquely identifiable card, to the consumer for use during consumer purchases. The consumer is invited to anonymously register the instrument (e.g. card). This registration process invites the user to provide anonymous demographic data. Uniquely identifying information, such as name, address, phone number, and/or birth date is not be requested. When consumers then use the card during purchases, sales information is automatically captured at the point of sale. The demographic information and the consumer purchase information can be linked to obtain a clear picture of the demographics of the consumers that made the purchases. This information can then be used for a variety of purposes, including marketing research.

Abstract: A system and method that anonymously collects and uses consumer purchase data, including radio frequency metrics, linked to individual characteristics, including demographic and attitudinal profiles of each user, while protecting individual user's identities. Uniquely identifying information about the user is not requested or recorded, keeping individual users anonymous and protected from unrequested solicitations, identity theft, and disclosure of individually identifying information to any third party. This data can then be used for a variety of purposes, including mass marketing, individually targeted marketing, and market research.
