Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for easily displaying on a card an image of the progress of things such as accumulated points of a point service as a degree of achievement for a specific situation such as a goal. It also relates to the cards used for this.

[0002]

2. Description of the Related Art Conventionally, various cards such as a point card having a magnetic stripe as an information recording section have been widely used, and an IC is used as an information recording section other than the magnetic stripe.
Cards and the like having a memory have also appeared, and more recently, cards that also have an information display unit capable of repeatedly rewriting the display by external energy have also appeared. In addition,
The information display unit uses a reversible display element such as a polymer / fatty acid composite film or a liquid crystal / polymer composite film, which can reversibly and repeatedly rewrite visible information using heat, an electric field, a magnetic field, or the like. The member number for identifying the owner of the card is recorded in the information recording unit, and when the card is set in the reader / writer when the member uses the card, the member number is read out and the host By reading the accumulated points of the member registered in the computer and printing the new accumulated points on a receipt or the like, the member has a mechanism to know his / her own accumulated points. Also, if the card has an information display unit, the accumulated points are displayed on the information display unit, and the display is rewritten each time the accumulated points are updated, so that the member always carries the card without receiving a receipt. You can know the latest accumulated points of yourself. As described above, by providing the information display unit on the card, the latest accumulated points can be known from the card in the point card. Further, even in the case of a prepaid card, the latest accurate prepaid balance can be confirmed by providing the information display unit.

[0003]

However, in the conventional method of using the display of the information display unit, for example, the accumulated points are displayed as "point 30" or the prepaid balance is "balance 2.
"500" or both are displayed using characters such as numbers. However, for example, even if the current accumulated points can be recognized on the display by the point service, it is not immediately known what the significance of the accumulated points is. For example, if you can receive a product service if you accumulate up to the target value of 100 points,
If the target value is different, such as when you can receive goods and services after accumulating points, the current accumulated points "3
The meaning of "0" naturally differs. That is, what percentage has reached the number of points that can be exchanged (the ratio of the current numerical value to the target numerical value), or how many more points will be reached or has already been reached. The comparison information of the current numerical value with respect to the target numerical value, that is, (difference of the current numerical value with respect to the target numerical value), that is, the “achievement degree” is the information which has the final meaning. Also,
Even if the target numerical value is also displayed by characters such as numbers, it is necessary to visually recognize the displayed numerical information and the target numerical value, and then start thinking through calculation using these both numerical values. Understand the meaning (for numbers). In addition, it will be described later that the target numerical value is a numerical value that is aimed at achieving the goal and is a kind of the specific numerical value including the meaning that the goal is not achieved.

Therefore, even if a card provided with an information display section is used only with letters and numbers, it has a descriptive power such that its meaning can be perceptually recognized at a glance, because it is based on the descriptive symbols such as numbers. However, there was room for improvement in terms of ease of information transmission. In addition, when displaying with only letters and numbers, there are restrictions on the display size and the number of display characters. In addition, even if the display amount of letters and numbers is increased, it is not possible to sufficiently express the degree of achievement of a thing by being bound by the restriction of expression by the essay symbol, and it is restricted by the limit of the expression by the essay symbol. It Therefore, an object of the present invention is to make it possible to intuitively and easily understand the meaning of numerical information regarding the progress of things such as accumulated points of a point service.

[0005]

In order to solve the above-mentioned problems, the achievement level indicating card system of the present invention comprises:
A card having an information recording unit and an information display unit that repeatedly rewrites visible information with external energy, at least reading of information from the information recording unit, and a reader / writer that rewrites visible information to the information display unit,

FIG. 1 is a schematic system configuration diagram of an embodiment of a business card system.

First, FIG. 1 is an external view showing an embodiment of an achievement degree display card of the present invention, which is used in a card system for carrying out a point service system as one embodiment thereof. An information display unit 4 including a reversible display device using magnetic microcapsules is provided on the front surface of the achievement level display card 10.
After "Points", 70 characters will be displayed to indicate that the present service can be received, and a picture image 5 representing a purse as a bag for coins is displayed. About 30% of the bottom of the bag is dark color. And the degree of achievement is about 3
It means that it is a percentage. The achievement level display card 10 shown in FIG.
When the IC memory has the C memory 2 and the optical memory 3, and the point information such as accumulated points is recorded in the IC memory, the card itself can manage the numerical information related to the point information.

The information display section 4 of the card is composed of a conventionally known display element capable of reversibly and repeatedly rewriting visible information by using heat, electric field, magnetic field or the like as external energy. For example, it is transparent by heating and cooling. Reversible display element of thermosensitive recording system that can be rewritten by reversibly changing between the state and cloudy state, reversible display element of electric and thermal recording system that can be rewritten by electric field and heating, and magnetic powder sensitive to magnetic field. A magnetic recording type reversible display element contained in microcapsules can be used. In the thermosensitive recording type reversible display element, a polymer / fatty acid composite film in which fatty acid is dispersed in a polymer matrix is used. In the electric / thermal recording type reversible display element, liquid crystal is dispersed in a polymer matrix. / Those using a polymer composite film or the like can be used.
The information display portion 4 may be provided on any surface of the card, such as the front surface, the back surface, or both surfaces, and may be the same surface as the surface on which the information recording portion is provided or a different surface. . Further, it may be provided at a plurality of locations (on the same surface or different surfaces).
You may use properly according to the application.

In the card system of the present invention, the achievement display of the present invention is used to display the achievement of things as a picture image on the information display section.
FIGS. 2A to 2C are explanatory diagrams showing how the pattern image 5 illustrated in FIG. 1 changes with an increase in the achievement level. Note that in FIG. 2, the information display unit 4 is assumed to be provided on the entire back surface of the achievement level display card 10 in order to enlarge the pattern image and make the description easy to understand.
2A, the achievement ratio of about 30% is represented by the area ratio of the hatched portion 51a of the hatched portion in FIG. Similarly, in FIG. 2 (b), the hatched portion 51b indicates that the achievement level is about 50%, and in FIG. 2 (c), the hatched portion 51c indicates that the achievement level reaches 100% (target value). . It should be noted that a scale may be added to the design image to make it easier to understand the degree of achievement represented by the hatched portion. Also, the achievement level is 0 on the scale.
(%), 50 (%), 100 (%), and the like may be added.

FIG. 3 shows the achievement level of the points when the achievement level indicating card 10 of the present invention having the information recording section and the information displaying section as described above is used and at least it can be used as a point card. It is a schematic system block diagram of one Example of the achievement degree display card system of this invention displayed as a design image. The card system shown in the figure is intended to use common points at a plurality of stores such as a shopping street and a chain store. In the system of the present embodiment, the generated points can be used in common for each store, so the point information such as accumulated points is not managed individually in each store, but is recorded in the commonly used achievement level display card 10. . The achievement level display card 10 is a CP
It is also an IC card with a built-in U, and point information is recorded in the IC memory from the viewpoint of ensuring its security, and the card itself can manage point information such as accumulated points. (The card is C from the viewpoint of security.
A PU is preferable, but a non-integrated IC memory card may be used. )

On the other hand, on the store side, a reader / writer and a data processing device are provided for each store. That is, store A
Then, the reader / writer 20 and the data processing device 30a, and similarly in the store B, the reader / writer 20 and the data processing device 30.
b. The data processing device 30a of the store A is C
The calculation control means including a PU is provided with a customer file 60 that stores customer information unique to the store A and an image file 50 that stores a pattern image showing the degree of achievement. It is a data processing means for calculating a degree of achievement and displaying a picture image corresponding to the calculated degree of achievement on the information display section of the card by the reader / writer. Further, the data processing device 30b of the store B differs from the data processing device 30a of the store A only in that the customer file is the customer file 60a for the customer unique to the store B, and the image file 50 has the same contents as the store A. It is a file. (Of course, the customer file may be shared.) Note that the image of the degree of achievement is the same for store A and store B, but if different image files are provided, the same degree of achievement will be obtained. Even if there is, it is possible to use the image of the image that matches the product or service of the store to express the degree of achievement. Further, when a customer already registered at the store A uses the unregistered store B, it is registered in the customer file of the store B based on the customer information registered in the customer master file 61 of the management device 31 at the time of registration at the store A. To be done.

Card reader / writer 20 provided in the store
Is a read / write means for reading / writing information from / into each information recording section of the card such as a magnetic stripe of a card, an IC memory, an optical memory, etc., and a display of a picture image of the degree of achievement displayed on the information display section of the card. Is provided with a rewriting means for rewriting. The rewriting means applies energy such as heat, electric field, and magnetic field to the reversible display element depending on the type of the reversible display element used in the information display section. The head is used as a rewriting means.

The data processing devices 30a and 30b, etc., provided in each store can be used by existing customers or (customer master files) in the store based on the customer number read from the magnetic stripe of the card set in the reader / writer or the information recording unit such as IC memory. (Registered in the) is determined, and the customer file of the own store is updated if necessary. Then, the cumulative points read from the IC memory of the card with the reader / writer are converted into achievement levels with respect to the target cumulative points held by the data processing device. One of the calculations is the difference x to the target value, and the other is the ratio y to the target value. The former is used to express the achievement level by the number and "characters (other than the number)" that are "x points until present". The latter is used to display the degree of achievement in terms of figure area using a picture image of a purse. As for the pattern images to be used, if the ratio y is expressed as a percentage, 11 types of pattern images are registered in advance in the image file in increments of 10% from when the achievement level is 0% to 100%. It should be noted that the increment may be appropriately increased or decreased in consideration of the actual size displayed on the information display section of the card. Then, the data processing device selects a picture image closest to the achievement degree calculated as the ratio y and controls the reader / writer to rewrite the display of the information display portion of the card with the selected picture image. Further, the difference x between the character and the numerical value up to the target value is also displayed on the information display unit by the reader / writer. It should be noted that the numerical part may be built in the program as a fixed sentence by the calculated difference x and the character part may be built in the program. The current number of points may be simultaneously displayed by numbers and letters.

Further, an office for controlling a plurality of stores is provided with a management device 31, and the management device is provided with a customer master file 61 for customer information of customers who have summed (logically summed) the customers of each store. By managing the customers as a whole and registering at one store, the card can be used at other stores without the same registration. For this reason, the data processing device of each store is connected to this management device through a communication line, and each store and office manages the customer by updating the customer file and the customer master file. Then, the management device 31 is provided with an image file 51 of a picture different from the picture image prepared by the store for each shop, and it is also possible to use the picture image unique to the office by transmitting it to the shop. ing. If the management device has an image file,
If the image of the design is used commonly in each store, the image file in each store can be omitted. However, it is more efficient to prepare a picture image having a large amount of data in each store, rather than transmitting it from the management device to each store by data communication each time.

Next, an example in which the above-described system and card are used to display the degree of achievement in a certain shopping mall will be described.

In this shopping street, 1 point is given for every 100 yen of shopping, and when 100 points are given, 1 point is given.
It is assumed that a service that allows you to shop for ¥ 00 is provided. Then, when the customer makes a purchase of 500 yen and sets the card in the reader / writer, the data processing device first reads and confirms the customer number of the card, and the accumulated points (probably 2
Also read 5 points. And the number of points to be given from the purchase amount of 500 yen input by the clerk,
5 points are calculated and added to the previous accumulated points (25 points) to obtain new accumulated points (30 points), and the accumulated points of the card are updated. Then, as illustrated in FIG. 1, the achievement level is displayed instead of displaying the accumulated points on the information display portion of the card. That is, regarding the achievement level, the difference x between the new cumulative points (30 points) and the target points (100 points) x
(70 points) is calculated, and the difference is replaced with the display of accumulated points, and the achievement level based on the difference of "70 points left until the present", which is a display composed of numbers and characters, is displayed. Further, the ratio y (0.3 = 30%) of the cumulative points to the target points is calculated, a pattern image corresponding to the ratio y is selected from the image file, and is used for the achievement level display by the ratio using the pattern image. . The accumulated points may also be displayed together.

The above is a system and a card that can provide a point service common to a plurality of stores in a shopping mall.
Another embodiment of the present invention shown in FIG. 4 is an example of a POS interlocking type online system and a card for a large store that interlocks with a POS (point of sale) system for managing sales information of a plurality of stores. In the figure, each store is provided with a plurality of POS registers, and the information of the POS registers is collected by the data processing devices 30c and 30d for each store.
1a. A point service function is added to the function of the normal POS processing, and the achievement level display card 10 in which the point information is recorded in the IC memory is used here as in the system of FIG. In the store A, the reader / writer 20 and the POS register 40 are installed for each cashier counter in the data processing device 30c. At store B as well as store A, reader / writer 20, POS
The register 40 and the data processing device 30c are provided. The data processing device 30c includes an image file 50 in which a pattern image representing the degree of achievement is stored and a customer file 60,
Further, the data processing device here also has a function necessary for the POS processing in addition to the data processing device in the system of FIG. 3 described above. Then, the data processing device 30c displays P
A picture image is displayed on the information display section of the card by the reader / writer via the OS register. Further, the management device 31a installed in the head office also has an image file 51 unique to the management device in addition to the functions necessary for the POS processing, and a picture image for achievement level display unique to the head office is provided as a card if necessary. Can be displayed on the information display section.

Another embodiment of the present invention shown in FIG. 5 is an example of a system for small-scale retail stores and an achievement level display card used for the system. The system is a stand-alone type system used independently in one store. Is. In the system shown in the figure, the functions of the reader / writer and the data processing device necessary for displaying the achievement level are built in a normal register, and the reader / writer built-in register / data processing device 32 is used for the image file 50 and the customer file. 60, and a point file 70 that stores point information such as accumulated points for each customer, and this one unit can perform all necessary processing. Further, the achievement level display card 10a used in the system of the same figure does not have point information unlike the achievement level display card 10 used in the systems of FIGS. The point information is stored in the point file of the data processing device 32. Therefore, the achievement level display card 1
Since 0a does not record point information for which security is desired to be secured, an inexpensive card having only a magnetic stripe recording a customer code as an information recording unit may be used. Therefore, the function for the information recording unit of the card of the reader / writer built in the register / data processing device is (the customer code does not need to record the point information).
It only needs to be read. In addition, the system of FIG.
The portable handy terminal 33 is also provided, and the handy terminal has a built-in reader / writer so that the achievement display and information can be read on the card other than the cashier counter. The point information and the customer information are centrally managed by the data processing device 33, and the handy terminal exchanges necessary information such as the achievement level with the data processing device through online data communication through a communication line such as a wireless communication. Image file used for display is image file 50
Use the one you own. It should be noted that at least the data processing device 32 has an arithmetic function for calculating the achievement level as necessary, but any handy terminal may be used. If it is not provided, the calculation result may be received by leaving the calculation to the data processing device side. Also, if the storage capacity of the handy terminal allows, fixed information files such as customer files and message files may be provided in the handy terminal.

As described above by taking the point service as an example, in the achievement level display card system of the present invention, numerical information that is a source of the achievement level (for example, successive product purchase amount and its total, accumulated points, etc. and target total) Numerical information of purchase amount, target points, etc.) or achievement level itself, or numerical information of both of them may be present in the card, the data processing device, etc., and is optional, and the system of the card, the reader / writer, and the data processing device. The system may be constructed according to the usage environment. If the information is recorded in the information recording section of the card, the card itself can manage the numerical information or the numerical information of the achievement level.

As for the definition of the degree of achievement, up to now, the point service, which is the ratio of the current numerical value to the target numerical value (which is the target to be achieved) or the difference between the current numerical value and the target numerical value, has been described as an example. It was But,
In addition to the case where there is a goal to achieve something called "goal", it may be a "specific" numerical value that is not the goal to achieve. For example, let's say that if you fail in a certain game using cards, damage points will be added and there is a warning point that the total number of damage points should not exceed. Then, it can be said that the warning point is not a target, and is a specific numerical value specified with a meaning different from other numerical values (cumulative number of arbitrary damage points). In addition, the target numerical value is a kind of subordinate concept of the specific numerical value. That is, the achievement level of the present invention means the progress of things with respect to a specific numerical value. In the case of a specific numerical value that is not the target numerical value, it may be more meaningful to call the achievement level than the achievement level. However, the achievement level in the present invention includes the achievement level. It should be noted that if the current position of the damage point with respect to the warning point is displayed as the difference or ratio in the above game, it will be easy to understand sensibly.

In the point service, the current numerical value is increasing toward the specific numerical value which is the target numerical value. However, conversely, the current value may decrease toward the target value or the specific value. For example, let's consider a service in which a prepaid card of 50,000 yen is provided here, and when the remaining amount reaches 20,000 yen and when it reaches zero yen, a crude product is provided. The point is that if you use the prepaid card well, you will be offered a service. (Note that in the system of the present invention for prepaid cards, the card has balance information that is sequentially updated in its information recording unit, and the reader / writer reads and writes this to update.) In this case, the balance. 20,000 yen is the first target value, and zero balance is the second target value. Then, the current value will decrease from the initial state of 50,000 yen.
However, in this case, 20,000 yen is certainly the target value, but if we try to apply the meaning of "the ratio of the current value to the target value" to this, then the current balance ÷ 20,000 yen makes a significant sense. I don't. However, the remaining amount of 20,000 yen is the consumption amount of 30,000 yen, and this consumption amount of 30,000 yen is also a target figure when the same situation is seen from a different point of view. That is, the current remaining amount is similarly replaced with the current consumption amount, which is the current consumption amount / 30,000 yen. This is the ratio that is (indirectly) related to the target value (20,000 yen), and the ratio that is (directly) related to the target value (30,000 yen) from another perspective. Alternatively, if the difference is the difference between the current numerical value and the target numerical value, the achievement level may be the current balance of 20,000 yen. And the second goal was zero yen, but if it is displayed in the meaning of the difference, it is nothing but the remaining amount display, but in this example, the remaining amount display is the display as the degree of achievement, and there is a special It is a display for “things” to which a meaning as a target numerical value having a different meaning (obtaining a crude product in the above example) is given. In this regard,
Achievement level display with the remaining amount of zero yen as the target value is rather replaced by replacing the remaining amount of zero yen with the consumption amount of 50,000 yen in the same manner as above, and displaying it as the current balance or the ratio of the current consumption amount to 50,000 yen. By doing so, the merit of the present invention can be applied more clearly and meaningfully to the balance display of the conventional prepaid card.

The above-mentioned "specification" of a specific numerical value means that when the state of another certain state B with respect to a certain specific state A is displayed as the degree of achievement, the state of the state A is different from other states. It is specific in that they differ, and the content of the cause to be specified is arbitrary. If this specific value is taken as an example of the above prepaid card, the remaining amount of a normal (normal service such as the above example) prepaid card is zero yen. In other words, it is the vanishing point of the monetary value (= the entire amount is consumed) and has a different property from other balances. If the present invention is applied to this concept, the total possible consumption amount (prepaid amount) of the balance or the consumption up to now (although the normal balance may be displayed) even if there is no special service By displaying the ratio to the achievement level, it is possible to grasp the progress of things (use) based on the concept of the percentage such as what percentage of the value of the owned card is used or what percentage remains. .

Next, as an information recording section of the achievement level display card of the present invention to be used, a magnetic stripe, an IC memory card (without a CPU) or an I (with a CPU) is used.
It may be an IC memory used for a C card or the like, or an optical memory or the like, and at least a card identification code such as a customer number for identifying the card may be recorded.
If the card does not have the numerical information necessary for calculating the achievement level, the data processing device holds it. Also, the reversible display element used in the information display part of the achievement level display card reversibly repeats visible information by external energy, such as a polymer / fatty acid composite film, a liquid crystal / polymer composite film, in addition to the magnetic microcapsules. It is arbitrary and not limited as long as it can be rewritten. Further, when using a design image, the design and the like are arbitrary, and the expression of the achievement level is not limited to the hatching display, and may be expressed by the size of the design or the like. In addition to the information regarding the achievement level, it is of course possible to display the current numerical value such as the current number of points and the information regarding the current state as in the conventional case.

[0025]

In the achievement level display card system of the present invention and the achievement level display card of the present invention, since the achievement level of an object can be displayed as a pattern image, the progress of a goal toward a specific state such as a goal can be visually indicated. , Intuitively understandable. For example, when a card is used in the point service, the achievement level of the cumulative points at that time with respect to the target points of the product exchange, the degree of difference, etc. can be easily and intuitively recognized as a picture image at a glance. Further, if the characters and numbers are displayed together with the picture image, the recognition becomes more accurate and easy. Besides the point service,
As the degree of achievement of things, it is possible to display the usage rate of the prepaid card or display for various purposes such as sports clubs, learning-related services, services other than points at retail stores, games, and amusement such as stamp rally. Therefore, in addition to stores, it can be effectively used in various facilities such as membership sports clubs.
