Abstract: A method and system for advertising that provides advertisers with a marketing database listing contact information for all potential consumers who received a promotional item from that advertiser and decided to retain the promotional item for future use. The promotional item is a tag bearing an advertisement, a contact identifier and a unique tag identifier. After receiving the tag from an advertiser, each recipient is instructed to attach the tag to a personal property item and to register the item with a processing facility that, with the use of an information storage and retrieval system, will create a master database comprising each recipient's contact information and tag identifier. The master database can be used to arrange for the return of a lost personal property item bearing a registered tag. The master database can also be sorted and contact information can be extracted therefrom to generate a marketing database for transmittal to advertisers.
