    description
    The invention relates to a system for reading an identification code from a customer loyalty program, which is stored on a mobile phone.
    According to the so-called "Visible Light Communication Technology" (VLC) technology, variations in the intensity of visible light, preferably of individual color portions of visible light, are used selectively to transmit information from a transmitter to a receiver. Several examples from the patent literature may be mentioned here:
    As early as 1989, JP 1122220 A proposes transmitting information by means of visible light, which also serves as illumination. The intensity of three color components of the light (red, green, blue) is allowed to fluctuate with changing, high frequencies, the height of each frequency means information. A receiving device selectively receives the color components, also detects the respective frequencies and reassembles the original signal from this information. In an exemplary application, lighting fixtures disposed in the vicinity of an exhibit object transmit an audio signal to a receiving station located in the vicinity of the exhibit and are audible by the receiving station for present viewers. Since the frequencies of the individual intensity fluctuations are so high that they are imperceptible to humans, no viewer notices that the lighting is actually flickering.
    By JP 29233025 A 1997 is proposed to realize a simple and fast digital wireless data transmission by means of visible light. The data present as a serial digital electrical signal are transmitted as three bit packets at the same time by three light sources, wherein the light sources are selectively switched on and off and turned on 1 2/18 1707 12 11:05
    Bluesource +4372363343909 S.5 BS 01 • · · ····· ···· ; 1 " means and off, for example, " 0 ". If necessary, the three light sources shine in exactly one of three primary colors (red, green, blue). The receiving station receives the light of all three light sources, it has three color-selective optoelectronic sensors for exactly one of the primary colors. The receiving station detects the pulses in the individual primary colors and produces the original digital signal again.
    According to US 7949259 B2, visible light is used for data transmission, again sending and receiving the three primary colors selectively. Since there are eight combination options of the primary colors by inserting and removing three primary colors, eight different characters can be encoded, ie each clock pulse of one of eight possible characters can be sent.
    The documents US 2008253202 A1, US 7917034 B2, US Pat. No. 797 4536 B2 propose the use of intensity-modulated visible light as a bidirectional communication medium between mobile telephones, using the display area of the mobile telephone or a separate light source on the mobile telephone as the required light source of a mobile telephone can. By using visible light, larger light intensities can be used than in the more popular infrared transmission where the intensity can be very limited for safety reasons. By being selectively modulated in different spectral regions of the light, several transmission channels can be realized in parallel and, overall, a high data transmission rate can be achieved. The procedure has not prevailed; presumably because, based on the amount of data to be transmitted, the energy expenditure required for transmission is relatively high and because significantly faster light elements must be used for a conventional transmission speed than are currently used for display areas on mobile telephones

    A large number of companies, especially retail companies, which operate purchasing markets, issue a customer card to their customers, with the help of which customers can identify themselves to the company and thus can be clearly identified by the company. The trading company benefits because it enables it to become better acquainted with the purchasing behavior of customers and thus better adjust to the individual customer. Customers can benefit from discounts coupled with a loyalty card, more targeted information and easier shopping. In addition to information such as an identification of the company and the name of the customer, a unique identification feature for the card in the form of an electronically simple and reliable readable code of binary symbols is attached to the customer card. In most cases, this identification code is a bar code, ie a series of juxtaposed black lines of equal length on a light background, wherein a string is coded by the thickness and spacing of the lines. If the customer identifies himself to the company, for example when entering a shopping market or at the point of sale of the shopping market, the electronically readable code is read from the customer card by means of a code reader. Information about the customer is generally not stored on the card, but in a centralized server, where the data record can be accessed by means of the identifier code attached to the customer card.
    With the emergence of mobile phones, which in addition to a data storage also have a display area sufficiently dissolving display image, it is common practice to stir customer cards no more than physical cards, but virtually, 3 4/18 1707 12 11:06

In addition, coupons are no longer carried on paper, but as a file on the mobile phone.
    US 2010149187 A1 describes the provision of a virtual loyalty card on a mobile telephone by data transmission from a server of the enterprise to the mobile telephone and in particular the representation of the customer card belonging bar code on the display surface of the mobile telephone. For bar code scanners designed for reading printed bar codes, a bar code displayed on a display surface of an electronic device such as a mobile phone is rarely readable. In many types of display areas of mobile phones, the reading process is impossible or possible only after many attempts.
    The documents US Pat. No. 6,749,120 B2 and US Pat. No. 6,877,661 B2 are already concerned in 2004 and 2005 with scanners which can read a bar code from a display surface of an electronic device. It is taught to a variety of technical artifice. In fact, to date, no satisfactorily cost effective technology that works reliably for all types of display panels of mobile phones has become widespread. It is unclear if there is any technology that has the potential to do so.
    The optical scanning of a bar code displayed on a display surface serving as an output surface of an electronic device involves considerable difficulties. Therefore, in many places in connection with stored on mobile phones virtual loyalty cards completely refrained from using this transfer method. Instead, the (alphanumeric) string that identifies the identification code and to which the barcode is only one of many representation strings, will become 4 5/18 1707 12 11:06

    Possibilities is sent by means of one of the usual for mobile phones wireless transmission technologies such as SMS, wireless LAN or Bluetooth from the mobile phone to a receiving station of the company. A disadvantage is that at least once a somewhat more elaborate " acquaintance procedure " between the respective mobile phone and the respective receiving station is required. Another disadvantage is that not necessarily local proximity is required between the receiving station and the mobile phone for the identification process. There is a risk that unwanted " identification " takes place or an identification process between a mobile phone and a receiving station is disturbed by other nearby mobile phones.
    The object underlying the invention is to provide a method for data transmission and a matching system, by which stored on a mobile phone identification codes from customer loyalty programs, so belonging to a virtual customer card identification code and identification codes for virtual vouchers, wirelessly transmitted to a reading device can be. Compared to existing methods and systems that already fulfill this task, the entire transfer process for the person using the mobile phone can be made more straightforward and the transmission should still work very well, reliably and error-free. For solving the problem, it is proposed to use visible light as the transmission medium and to encode the information by switching spectral regions of visible light on and off. The corresponding system comprises the mobile telephone, which must be the sending part and a reader, which must be the receiving part,
    As the light source of the cellular phone, the display surface of the cellular phone is preferably used. The reader must have an opti-5 6/18 17071211: 07

    see sensor (which may be composed of several sub-sensors) arranged to be illuminated by the light source of the mobile phone and which is capable of displaying the states " Turned On " and " turned off " to detect selectively for the spectral ranges used.
    The invention will be clarified with reference to a drawing: Füg. 1; shows something stylized an example of the invention ir plant. Side view. Invisible lines are shown in broken lines.
    The system according to FIG. 1 comprises a mobile telephone 1 and a reading device 2.
    In response to signals from the control of the mobile phone 1 toward the display area 1.1 of the mobile phone 1 over a large area, - preferably over the entire area - from a given range of colors each accept a single color and switch between such color representations, each with different colors. The mobile phone contains in a program memory a program which codes on command of the operator out according to an assignment rule alphanumeric characters as a color sequence and outputs as a color sequence to the display area 1.1.
    The reader 2 includes an optoelectronic detector 2.2, which is arranged in the dargesteilten version protected in a recess 2.1 in the housing of the reader and is covered to the outside by a converging lens 2.3 and transparent protective screen 2.4. The optoelectronic detector 2.2 is able to provide an electrical signal of its kind and / or size before. Color and intensity of the light striking him depends on it. In a simple exemplary embodiment, the detector 2.2 may be a small, color-selective CCD sensor, that is, an arrangement of several, to different colors

In the example shown, the illustrated reader 2 via a line 2.5, via which energy and data can be transmitted to another device such as an electronic cash register of a cashier's workstation connectable. For the transmission of the identification code of a stored on the mobile phone 1 virtual customer card from the mobile phone 1 to the reader 2, the customer card is called by a program on the mobile phone and the program is selected that the identification code is to be transmitted by coded visible light. Then, the mobile phone 1 is held as shown with its display surface 1.1 to the recess 2.1 on the reader. Finally, the shutter button 1.2 is pressed on the mobile phone 1. The identification code is displayed by the display area as a color sequence and thus sent as a light signal. The light emitted by the display surface passes - slightly focused by the lens 2.3 - to the optoelectronic detector 2.2, which again generates electrical signals from the built-in reader 2 electronic processing device according to the above-mentioned assignment rule in the original alphanumeric string is re-translated. This string can be made available for other applications in the same way as a conventional bar code scanner (or even semiacode scanner).
    Compared to previously considered applications for data transmission with visible light, the application proposed here is very advantageous. Since each data transmission case only a few (maximum of about 20 characters) alphanumeric characters must be transmitted, it does not matter if the data transfer in relation to the amount of data compared to today's usual transfer rates - extremely slow going on. In any case, the number of color changes which the display area of conventional mobile telephones can make clearly and reproducibly per time is sufficient to satisfy the 7 8/18 170712 11:07

    • ······················································································································· For this, the data transfer rate does not even have to be one kilobit per second.
    This means that all of today's popular mobile phones are in terms of their hardware to be able to be part of the system according to the invention. It only requires the mobile phones to play the appropriate program and, of course, the customer card (s).
    In an advantageous construction, the opening area of the depression 2.1 on the reading device 2, in which the optoelectronic detector 2.2 is arranged, is smaller in both dimensions than the smaller dimension of the (rectangular) display area 1.1 of the mobile telephone 1. As a result, the opening area is well visible through the display surface of the mobile telephone Cell phones coverable and the influence of ambient light is minimized.
    In order to avoid erroneous transmissions and to avoid that a transmission is detected by the reading device, although no transmission has taken place, simple checks to be implemented in the reading device by software are sufficient. For example, it may be required that a certain minimum number of color changes have taken place within a certain time and that only intensity values that are above an upper threshold or below a lower threshold are recognized as part of the code.
    In terms of the invention based advantageous modifications and additions to the previously described as an example construction and operation are further explained:
    It is quite possible to use a sensor 2.2 on the reader 2 without previously arranged converging lens 2.3 and also without protective cover 2.4. You can also arrange the sensor 2.2 flush with the surface of the reader housing. 8 9/18 1707 12 11:08

    In an advantageous mode of operation, the eventual transmission of the identification code by the mobile telephone 1 is not triggered by the pressure of a key 1.2, but by the fact that the mobile telephone 1 - on which previously readiness for transmission was produced - is placed with the display side down on a surface and not more is being moved. Through a position and motion sensor, as they are installed in almost all newer mobile phones today, recognizes the control of the mobile phone 1 that the phone is quiet with the display side down and indicates that as a command to send the identification code.
    In a further preferred mode of operation, the mobile telephone repeatedly transmits the identification code and the repetitive transmission of the identification code is aborted by moving the mobile phone.
    Thus, the operation is extremely easy and it is avoided that the mobile phone 1 emits disturbing light pulses into the environment. Repeated sending creates redundancy, which automatically corrects erroneous reads.
    In repetitive transmission of the code, it is inevitable that in addition to the information significant to the characters of the code, information is also sent, which is the beginning of the string meaning the code. For example, as information that the end of the identification code has been sent or that the beginning of an identification code will be sent at once, the 1 will be sent six times followed by a 0.
    Corresponding to a coding that is particularly robust and yet very fast against read errors, the characters of the identification code to be transmitted as well as possibly the information indicating the end of the identification code are displayed in a binary code and the " 1 " or " 0 " are used as alternations between two colors. 9 10/18 170712 11:09 Bluesource +4372363343909 p.13 ··· . Colors encoded in a predetermined, closed order of at least three different colors, starting from that of those colors currently present, to represent a " 1 " in one direction the next color is displayed and to display a " 0 " in the other direction the next color is displayed. For example, the colors red, green, blue can be used. To represent " 1 " will change from red to green or from green to blue, or from blue to red. To represent "0 " is changed in the opposite direction, ie from red to blue or from blue to green or from green to red.
    This makes it possible to achieve that the transmission works completely independently of a clock frequency and that only the same number of switching operations are required as to transfer ones and zeros. In spite of the fact that the transmission takes place without a clock synchronized between transmitter and receiver, there is no need for any additional information to make identically sequential numbers transmitted as a number sequence instead of just one digit. There is no need for a voting process to set the reader 2 to the speed at which the various mobile phones 1 used can switch between the individual colors. Currently common mobile phones provide about 30 to about 100 color changes per second, which means a transfer rate of 30 to 100 bits per second.
    In an advantageous mode of operation, the thresholds of brightness (intensity) at which a color is displayed as being "" applies, continuously calibrated. This ensures that the data transfer works regardless of the display brightness of the mobile phone used. This also ensures that the transmission can also work if the mobile phone is not placed on the reader, but at a distance of a few centimeters, 10 11/18 1707 12 11:09

    Before the start of a transmission, a basic calibration can be carried out, in which the mobile phone simply displays bright white for a short time and the reading device calculates a threshold value for the intensity in the individual colors from the intensity measured in the process.
    The reader 2 does not necessarily have to include an electronic processing unit which re-translates the immediate results of the sensor 2.2 into the identifier code. Of course, this electronic processing unit can also be contained in a device which is not contained in the reader 2, but only in data transmission connection with it. 11 12/18
