Description

SMART CARD DATABASE
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to the field of smart cards. In particular, the invention relates to a file structure employed in smart cards for facilitating commercial transactions. Description of the Related Art
Traditionally, coupons are represented and redeemed by printed matter, which may appear in newspapers or other publications. Likewise, consumer loyalty programs are administered by use of physical punchcards. There are inherent limitations in the use of printed materials for coupons or loyalty programs which render them inadequate for the age of digital transactions. For instance, printed coupons do not allow for one-to-one marketing, as they demand substantial time and cost to print and deliver to the potential user. Moreover, printed coupons and loyalty punch cards are cumbersome to handle.
Smart cards have been proposed as a medium for facilitating promotions such as coupons and loyalty programs. The ubiquity of handheld wireless appliances allows the smart cards to include promotional data transmitted to the wireless unit. This creates an unprecedented opportunity for one-to-one marketing. As such, there is a need for a file structure on such smart cards to facilitate promotions received from wireless units.
SUMMARY OF THE INVENTION
The invention comprises a file structure for a smart card used to conduct promotions, such as coupons and loyalty programs. In particular, the smart card can be read from or written to by a wireless device, which may receive data for the promotion through a wireless medium. The promotion is conducted by a consumer who presents the smart card at point of sale. BRIEF DESCRIPTION OF THE FIGURES
Fig. 1 illustrates a file architecture for a smart card supporting promotions according to an embodiment of the invention.
A. System Overview
The present invention comprises a file structure that enables smart cards to support commercial promotions, including but not limited to coupons and loyalty programs. The smart card may be redeemed at a point of sale, such as in a supermarket, to redeem coupons or loyalty points. In embodiments of the invention, the smart card may also be accessed by a portable device which may read from or write to the card. Such a device may also be referred to as an electronic "wallet." The wallet may also receive data via a wireless connection, such as a wireless phone transmission, or a wireless optical signal from a monitor, as described in U.S. Patents 5,594,493, 5,767,896, 5,880,769, 5,907,350, all of which are herein incorporated by reference in their entirety
In embodiments of the invention, the file structure may include the following files:
• Header File 100. This file contains information pertaining to the card as a whole. It is a transparent (i.e., binary) file and comprises one record.
• Coupon File 102. This file contains coupon records. It is transparent. The number of records in the file depends on the amount of memory available on the card.
• Punchcard File 104. This file contains punchcard (loyalty program) records. Like the coupon file, it is transparent and its size depends on available memory.
• Frequent Shopper Alias (FSA) File 106. This file contains frequent-shopper alias records. It is a transparent file. Its size also depends on available memory. • Text File 108. This file contains display text records for those manufacturers not represented in the Wallet's Flash-based manufacturers profiles database. It is transparent and its size depends on the amount of memory available on the card.
• Secret Key File. This file contains 4 double length secret keys. These keys are not currently assigned to a specific file access regimen.
• Serial Number File. This file contains an 8 byte serial number. These files shall be described in greater detail infra.
B. File Organization
All files described are elementary (data) files that reside within the same dedicated (directory) file. This dedicated file lies just beneath a master file. In embodiments of the invention, the other files are all fixed-length and are created during the manufacture process. In a non-limiting embodiment of the invention, the files may have identifiers. As an example, these identifiers may be:
2B00 Directory 2080 Secret Key File 2B02 Header File 2B03 Coupon File 2B04 Punchcard File 2B05 FSA File 2B06 Text File 2B08 Serial Number File.
C. File Contents
The contents of the individual files are described herein.
Header File
In an embodiment of the invention, the header file 100 includes a single record comprising the following fields:
Wallet ID. 4 bytes.
Household ID. 8 bytes.
Serial Number. 8 bytes.
Database Version. 1 byte.
Last Update Source. 2 bytes.
Last Update Time. 3 bytes.
Maximum Coupon Count. 2 bytes.
Maximum Punchcard Count. 2 bytes.
Maximum FSA record Count. 2 bytes.
Maximum Text record Count. 2 bytes. Current Coupon Count. 2 bytes. Current Punchcard Count. 2 bytes. Current FSA record Count. 2 bytes. Card Usage Count. 2 bytes. Total Coupons Redeemed. 2 bytes. Total Savings Accumulator. 4 bytes. Monthly Savings Accumulator. 4 bytes. Temporary Savings Accumulator. 4 bytes. Reference Month. 1 byte. Timezone. 1 byte. Internal Error Counter. 2 bytes. Flags. 1 byte Spare Bytes 39 bytes. • Checksum. 2 bytes.
Total file size = 100 bytes.
Coupon File
In an embodiment of the invention, the coupon file 102 includes records with the following format:
• UPC Manufacturer Code. 5 bed digits.
• UPC Family Code. 3 bed digits.
• UPC Value Code. 2 bed digits.
• UPC Offer Code. 5 bed digits.
• Expiration Time. 3 bytes.
• Start Time. 3 bytes.
• Capture Time. 3 bytes.
• Text File Index. 1 byte.
• Reuse Counter. 1 byte.
• Flags. 1 byte.
• Checksum. 2 bytes.
Total record size = 22 bytes.
Punchcard File
In embodiments of the invention, the punchcard file 104 includes records with the following format:
• RFM ID. 8 bed digits.
• Expiration Date. 2 bytes
• Release Number. 1 byte.
• Reset Period. 1 byte.
• Days Since Last Visit. 1 byte.
• Purchases Accumulator. 2 bytes.
• Visits Accumulator. 1 byte.
• Spare/Filler. 4 bytes Total record size = 16 bytes.
FSA File
In embodiments of the invention, the FSA file 106 contains records with the following format:
• Retailer ID. 2 bytes.
• Customer ID. 8 bytes.
• Checksum. 2 bytes.
Total record size = 12 bytes.
Text File
In embodiments of the invention, each text record 108 has the following format:
• Text Line #1. 20 bytes.
• Text Line #2. 20 bytes.
• Checksum. 2 bytes.
Total record size = 42 bytes.
Secret Code File
The size of this file is controlled by the card manufacturer.
Secret Key File
The size of this file is 64 bytes containing 4 double length keys.
Serial Number File
This file comprises a single 8 byte serial number. D. Access Methods
In preferred embodiments of the invention, files are accessed via secret codes (sometimes called PINs) as opposed to secret keys. Other embodiments utilize secret keys, and include a Secret Key file. In embodiments of the invention, codes presented to the card will be transmitted in the clear (not encrypted). This avoids the placement of cryptographic software in the wallet. In alternative embodiments, codes are presented to the card in encrypted format, and wallets include DES or other cryptographic software.
In some embodiments, the code for read-access is the same for all files, while the code for update-access is the same for all files, but different than the read-access code. There is no need for a code for write-access, as it is not needed for file creation. In embodiments of the invention, the secret codes are based upon diversification of a code derived from a scrambling of the card's serial number. Other embodiments for generating such codes will be apparent to one skilled in the art. Each serial number is unique and is created during the manufacture process. This serial number is generally distinct from the serial number assigned by the microprocessor manufacturer. The serial number can always be read in the clear.
E. File Sizes
In embodiments of the invention, the size of the Secret Code File and the Header File 100 are fixed. All other files may grow or shrink, depending on the amount of smartcard memory available. Non-limiting scenarios include:
• 1 Kbyte available, excluding Header and Secret Code, Secret Key, and Serial Number Files.
• Coupon File 102: 30 records for a total size of 660 bytes.
• Punchcard File 104 : 10 records for a total size of 160 bytes • FSA File 106: 4 records for a total size of 48 bytes.
