Abstract

The present invention concerns a process and a device of processing of coded information, during of an operation of purchased or payment by an incumbent client of a chip card at a shopkeeper. The memory of the chip card comprises a first file of identification, tells Member file, identifying the incumbent client of the card, a second file of posting, tells file Positions and a third file, tells Behavior file, concerning the behavior of the holder of the card with the commercial users. A determined algorithmic processing is undertaken according to a share of the date of the operation and on the other hand of information contained in files. One writes then data in the file Positions and new information in the Behavior file, and one prints or not the coupon, from result of the algorithmic processing.

Description

The present invention relates to a process for processing coded information during a transaction of purchase or payment by a customer holding a smart card at a merchant, in which the contents of the memory of the smart card are read and a coupon is or is not printed from the information from the contents of the memory.
It also concerns a device implementing such a process.
The present invention has a particularly important, though not exclusive, application in the field of processing loyalty cards presented at the time of payment by customers at a merchant, e.g. a hypermarket or supermarket type retail store, a gas station, or a car dealership.
Thus, with the invention, it is possible to modulate a commercial offer according to the cardholder's subsequent behaviour, which allows him to receive specific benefits in a personalised and immediate manner, which can also be recorded on the card.
A method is already known for granting specific benefits based on customer behaviour, which essentially consists of sending a discount coupon by post some time after the transaction triggering the purchase or payment by the holder.
This method has disadvantages: it is time-consuming and unreliable (loss of coupons, change of address).
One of the technical problems solved by the invention is to eliminate these significant delays by granting an advantage to the customer at the time of payment by the customer or more generally of the transaction triggering the advantage.
Err1:Expecting ',' delimiter: line 1 column 110 (char 109)
The merchant will be able to identify a customer according to the frequency of his visits and the volume of his expenditure and will be able to automatically grant him a specific advantage, which will be determined instantly.
For this purpose, the invention proposes, inter alia, a method of processing coded information during a purchase or payment transaction by a customer holding a smart card at a merchant, in which the contents of the memory of the smart card are read and whether or not a coupon is printed from the information from the contents of that memory, characterised by the fact that the memory of the smart card contains a first identification file, the Member file, identifying the customer holding the card, a second accounting file, the Points file, and a third file, the Behaviour file, concerning the cardholder's behaviour towards the merchant or merchants using the card, algorithmic processing is carried out, determined on the basis of the date of the operation and the information contained in the said files, including the Behaviour file, Then we write data into the Points file, we write new information into the Behavior file, and we print out or not the coupon, based on the result of that algorithmic processing.
In advantageous modes of production, one or both of the following provisions are also used: the algorithmic processing involves a step of incrementing or decrementing the Points file by a predetermined number of points; the coupon is printed only if the number of points contained in the Points file is greater than a specified value; the coupon is printed and/or the Points file is incremented or decremented only if the Member file meets certain criteria; the Points file is incremented or decremented according to the amount of the purchase or payment transaction; the Points file is incremented or decremented according to the frequency and/or location of the first, second or eleventh character of the cardholder over a specified period of time; information is introduced into a terminal for a specific operation, and information about the storage facilities, the location of the cardholder and the location of the payment terminal is compared with the information stored in the pre-operated storage facilities; the results of these comparisons are processed to print a coupon and/or write to the Points file;
This makes it possible to carry out promotional operations limited in time and on a group of traders belonging to the same network. Access to the files is encrypted by a so-called triple DES (Data Encryption Standard) encryption procedure.
The invention also proposes a device for processing coded information during a purchase or payment transaction by a user holding a smart card, including means of reading data coded in the memory of the smart card, means of calculation and means of printing a coupon, characterised by the fact that the memory of the smart card contains a first identification file, the Member file, identifying the cardholder customer, a second accounting file, the Points file, and a third file, the Behaviour file, concerning the cardholder's behaviour towards the merchant or merchants who use it, the means of calculation include means of algorithmic data processing based on the date of the operation and on the information contained in those files, including the Behaviour file, and the device has means for writing new information into the Points file and the Behavior file from that algorithmic processing, the means of printing a coupon being arranged to print or not to print that coupon from the information from the contents of those files and that algorithmic processing.
The advantage of this system is that it also includes: means of entering data corresponding to that operation into an intermediate memory and of displaying data,means of storing coded information relating to one or more operations,means of comparing the data entered into that intermediate memory with the information stored in those intermediate memory,means of processing the results of those comparisons,and means arranged to automatically print or not to print the coupon from information from the contents of the memory of the chip card,commanded by those means of processing those results.
The invention will be better understood by reading the following description of a particular embodiment given as a non-limiting example.
The description refers to the accompanying drawings in which: Figure 1 shows a general diagram of a device according to an embodiment of the invention.Figure 2 is a partial block diagram of a method of embodiment of the memory of the chip card in the device according to the invention.Figure 3 is a block diagram of the information processing process according to the embodiment of the invention more specifically described here.
Figure 1 shows a device 1 comprising a payment terminal 2 equipped with a card reader 3 with a 4 chip 5.
The payment terminal is, for example, the type marketed under the Delta 15 reference by the French company Schlumberger.
The smart cards used in the present invention are, for example, cards sold under the codes MP-COS of the French company Gemplus or ME 2000 of the French company Schlumberger.
They may be bank, credit or loyalty cards.
Terminal 2 comprises a keyboard 6, a display screen 7 and a calculator 8 programmable according to algorithms determined in a way known to itself.
The calculator 8 is connected to drive 3 via a read/write circuit and to a microcomputer 9 itself connected to mass memory 10.
The device 1 also includes means of printing 11 a coupon 12 connected to the calculator 8 and a cash register 13 and invoice printer, e.g. via a computer 9.
The calculator 8 is connected, possibly via computer 9, to means (not represented) entirely remote from the site where the device 1 is installed and arranged to ensure consistency of processing and/or information processed and collected by different devices at different sites.
The organization of a mode of realization of memory 14 of chip 5 of card 4 has been shown in Figure 2.
The card includes multiple applications, memory 14 including a main or root directory 15.
It is organized into directories 16, 17, etc.
The information concerning the cardholder or holder is contained in a file 18 called the Member file, under main directory 15.
A System 16 directory is planned, including, for example, a file 19 concerning the map itself and other types of files 20 known in themselves.

An advantageous implementation is to manage the security of card information by encrypting the codes according to card numbers.
The application includes, for example, two file access codes and two keys to the Points file.
They are used to calculate various codes and keys, which are then compared to the codes and keys inscribed on the card.
This diversification is done by the triple DES (Data Encryption Standard) procedure, applied to both the mother codes (or mother keys) and the card number.
The mother codes and mother keys embedded in the terminal are for example:Code01Member file update mothercodeCode12BehaviorKauth1Mother authentication key for PointsKcred1Mother credit key for Points
The mother codes or mother keys are also diversified and for example as follows: 1. The mother codes or mother keys (16 bytes) are divided into two equal parts of 8 bytes KL (left part) and KR (right part) 2. N (the first 8 bytes of the card number) is encrypted by KL: R1 = DES (KL,N) 3. R1 of 8 bytes is decrypted by KR: R2 = DES-1 (KR,R1) 4.
R is the result over 8 bytes of the triple DES diversification of a code or a master key, and therefore represents the value entered on the card.
An example of the operation of the device in Figure 1 is now described by reference to Figure 3.
The cardholder client user inserts card 4 into reader 3 (step 30), and the Member, Behavior and Points files are read (step 32).
A validity test 34 (expiry date) is then performed by comparison with the day date.
The amount of the purchase is then entered (step 36) either via teller 13 and microcomputer 9 or via keyboard 6.
If the sum is greater than a specified value (test 38), then algorithmic processing 40 is performed based on the information contained in the Member file, the Behavior file and the Points file.
The transaction results in a step 42 in which the Points file is increased by a number of points determined, for example, by the number of transactions carried out by the cardholder in the month.
Err1:Expecting ',' delimiter: line 1 column 102 (char 101)
A test step 46 is then planned comparing the number of points in the Points file to a defined threshold volume.
If the number of points is less than this, a message is sent in 48; if it is more, a coupon for a specific amount is printed (step 50).
The invention thus enables the cardholder to obtain two types of advantage separately or simultaneously: a credit of points on an electronic point counter in the card chip,a coupon for a discount printed at the time of purchase, to be used on the purchase itself or on a future purchase.
Several examples of how this works are given below.
The merchant may choose, for example, to give 2 points to his customers on their first visit of the month, 4 points on their second visit and 6 points on their third visit of each month.
Another merchant may choose to link the points credit to a transaction amount, so that on the first visit the customer will receive, for example, a point amount equal to 10% of his purchase.
Another retailer may choose to offer a coupon for a discount on a purchase from home, for example, the retailer may give 25% discount to first-time customers and 10% to other customers.
The coupon may be worth points, in which case the coupon is given to the customer for a percentage of points. For example, if the merchant offers a coupon for a 25% discount, for a 10 point amount, the coupon will only be printed if the card has a minimum of 10 points.
The invention also allows for targeting of precise cards.The merchant identifies card numbers in the Member file in advance, which will receive an advantage on their next visits.
This list of maps can also be downloaded from a central system via the external link described in reference to Figure 1.
Err1:Expecting ',' delimiter: line 1 column 202 (char 201)
This aspect of the invention can thus be used to identify customers who spend little at the merchant but a lot in an industry close to that of the merchant.
An example of the parameterization of the algorithm for the grant of benefits according to the invention is given below.
The algorithm is set to
