Abstract

A number of methods exist today, to prevent theft or the unauthorized movement of property. Many systems including the use of RFID technology are used to deter retail theft by affixing the anti-theft device to the merchandise in order to generate an alarm if the device is not deactivated prior to the merchandise leaving the store. A few systems exist to help in identification of the merchandise, these typically are in the form of a serial number or identification mark added to the external body of the merchandise. These forms typically take the shape of a metal or some other membrane tag attached to the exterior of the product for visual inspection. End users can further engrave a personal id onto the product either through use of permanent ink or engraving tools. In the case of merchandise such as autos, tracking devices can be employed for eventual recovery of the item. Such systems have significant limitations and disadvantages associated with their use. Identification tags or engravings can easily be removed or de-faced rendering the owner identification useless. Devices that can track a product and be used to identify the owner suffer from cost limitations and are often bulky limiting their use to expensive items such as autos.

A number of methods exist today, to prevent theft or the unauthorized movement of property. Many systems including the use of RFID technology are used to deter retail theft by affixing the anti-theft device to the merchandise in order to generate an alarm if the device is not deactivated prior to the merchandise leaving the store. A few systems exist to help in identification of the merchandise, these typically are in the form of a serial number or identification mark added to the external body of the merchandise. These forms typically take the shape of a metal or some other membrane tag attached to the exterior of the product for visual inspection. End users can further engrave a personal id onto the product either through use of permanent ink or engraving tools. In the case of merchandise such as autos, tracking devices can be employed for eventual recovery of the item. Such systems have significant limitations and disadvantages associated with their use. Identification tags or engravings can easily be removed or de-faced rendering the owner identification useless. Devices that can track a product and be used to identify the owner suffer from cost limitations and are often bulky limiting their use to expensive items such as autos.

In this publication, a concealed contact- less system is described that embeds Motorola's BiStatix™ RF identification (RFID) technology into conventional items for use in identification of the owner of the item. In particular the system relates to a novel method for embedding an RFID tag inside the items so as to become unnoticeable to intruders while allowing the owner of the item to store secure information that can be used in the identification and eventual retrieval of the item.

Items have irremovable tags incorporated into them. Typically this would involve the attachment of the tag to the inside cover of the item with antenna filaments designed into the cover in a manner that allows penetration of RF energies. The BiStatix™ IC contains a total of 1056 bits of EEPROM memory arranged in 32 individually addressable blocks of 32 bits of data plus an associated lock bit for block write

protection. Refer to TEMIC specification e5552. These blocks are logically separated into two parts, the product information section, and the owner information section. Blocks 26-31 are proposed to store owner identif...
