Description

Electronic magnetic stripe card

Technical field

The present invention relates to the field of analog magnetic strip technology, and in particular to an electronic magnetic stripe card. Background technique

A magnetic stripe card refers to a card that uses a magnetic strip as an information carrier. The magnetic material is coated on a card (such as a bank passbook) or a magnetic strip having a width of about 6-14 mm is pressed against a card (such as a bank card). According to the IS07811/2 standard, the first track can store 76 alphanumeric characters and is read-only after being first magnetically written; the second track can store 37 numeric characters, which is also read-only; the third track It can store 104 numeric characters, is readable and writable, and is used to record information such as book balance. The magnetic stripe of the magnetic stripe card is made of a granular magnetic material, and the magnetic stripe card passes through the working magnetic head with the coil at a certain speed, and the external magnetic line of the magnetic stripe card cuts the coil inside the magnetic head to generate an induced electromotive force in the coil, and further The signal recorded in the magnetic strip is transmitted.

With the development of the financial industry, people have more and more magnetic stripe cards, which are inconvenient to carry and use. Moreover, once the wallet storing multiple magnetic stripe cards is lost, it is also necessary to report the loss and replace multiple cards at the same time, which is very troublesome. The serialized magnetic field is stored on the magnetic strip, and the magnetic field information stored therein can be detected when the magnetic head passes over the magnetic strip. The varying current can also generate a serialized magnetic field through the coil, so the magnetic field can be simulated by controlling the current in the electromagnet to complete the action of transmitting magnetic field information to the magnetic head. By changing the current sequence through the coil, it is possible to change a magnetic stripe card into a plurality of magnetic stripe cards, which can be called "electronic magnetic stripe cards". That is, an electromagnet is used to simulate the magnetic stripe in the magnetic stripe card.

As shown in FIG. 1, the electronic magnetic stripe card 100 generally needs to include a data transmission component 101 (generally in the form of a chip), a processor component 102, a power component 103, and an analog magnetic stripe component 104. The power component 103 is responsible for powering the data transmission component 101 and the processor component 102. The data transmission component 101 is responsible for importing the traditional magnetic stripe card data from the outside in a wired or wireless manner, and the processor component 102 records the information and Data is transmitted to the analog magnetic stripe assembly 104 for magnetic card simulation. When the head passes over the analog magnetic stripe module 104 of the electronic magnetic stripe card, information such as the card number output by the processor component 102 can be read.

Specifically, when simulating a traditional magnetic stripe card, a device (herein referred to as hos t) can be provided, and the hos t has a card slot. First, a conventional magnetic strip can be inserted into the card slot, and the conventional magnetic strip can be read. In the card The data is saved to the hos t; of course, if the user has multiple conventional magnetic stripe cards, the data in each of the conventional magnetic stripe cards can be saved to the hos t in this way. When you need to simulate a traditional magnetic stripe card, you can insert the electronic magnetic stripe card into the hos t, and the interface provided by the hos t (may be the hos t own display, or by means of mobile phones, desktops, etc.) The display shows the list of traditional magnetic strip cards that have been entered into the hos t, from which the user can select the magnetic stripe card to be simulated, so that the data transfer component 101 of the electronic magnetic stripe card can read the traditional from the hos t The data in the magnetic stripe card is imported into processor component 102 to record the information and transmitted to analog magnetic stripe component 104 for magnetic card simulation. At this point, the electronic magnetic stripe card can be removed from the card slot of the hos t, and used for card consumption and the like. If the user needs to simulate another conventional magnetic stripe card next time, the above operation can be repeated, and other magnetic stripe card information can be selected in the list provided by the hos t, and the electronic magnetic stripe card can be used as the other conventional magnetic stripe. The card is used.

In the above manner, it is possible to simulate a plurality of conventional magnetic strip cards by using an electronic magnetic stripe card, thereby avoiding the need for the user to carry a plurality of conventional magnetic stripe cards. However, in the existing technology implementation, the phenomenon of simulation failure often occurs. For example, after the information of a conventional magnetic stripe card is imported into an electronic magnetic stripe card, when the card is swiped on a terminal device such as a POS machine, the card number information or the reading error or incompleteness often occurs.

Therefore, there is an urgent need for technical problems solved by those skilled in the art to: how to more effectively simulate the traditional magnetic stripe card and improve the success rate of the card.

detailed description

The above described objects, features and advantages of the present invention will become more apparent from the aspects of the appended claims.

It should be noted that, in the process of implementing the present invention, the inventors have found that in the prior art, when an electronic magnetic stripe card is used to simulate a conventional magnetic stripe card, the phenomenon of flashing failure often occurs because: The magnetic stripe simulation method uses a magnetic core with a uniform magnetic permeability direction as the core component of the analog magnetic strip. Figure 2 is one of the more representative ones, that is, the longitudinal coil is wound directly on the lateral core 201. 202, analog magnetic strip. A disadvantage of this magnetic stripe simulation technique is that the head can detect a higher amplitude of induced current at a portion of the entire analog strip (usually at both ends), in the remainder (usually in the middle-long section) only It can detect very small or even impossible to detect the induced current. In addition, the direction in which the magnetic head detects the induced current is also unstable, resulting in unstable detection or even failure of detection.

Figure 3 shows the average amplitude A of the induced current and the relationship between the direction and the head position coordinates detected by the head as it passes over the analog magnetic strip. Wherein, the abscissa X is the position of the magnetic head on the analog magnetic strip, L is the length of the analog magnetic strip, and the ordinate is the amplitude and direction of the average value of the induced current on the head. It can be found that the traditional magnetic stripe simulation technology makes the current induced by the detecting head very unstable both in magnitude and current direction, which easily leads to invalid card swiping. .,

Therefore, in the embodiment of the present invention, the electronic magnetic stripe card is improved from the perspective of improving the magnetic stripe simulation mode, so as to achieve a more effective analog magnetic stripe card and improve the success rate of the swipe card. The specific implementation is described in detail below.

Embodiment 1

In the first embodiment of the present invention, an electronic magnetic stripe card is provided, which can also be composed of the data transmission component 101, the processor component 102, the power component 103 and the analog magnetic stripe component 104 described in FIG. However, it is necessary to improve the magnetic stripe simulation of the analog magnetic stripe assembly. In the first embodiment, the improved manner is: an electromagnetic coil made of a wire wound and a magnetic core with an anisotropic magnetic permeability; wherein the magnetic permeability of the magnetic core is oblique, thereby Produces an oblique magnetic field. Here, the oblique direction means that it has a certain angle with the lateral direction, for example, the angle may be 45 degrees. Wherein, the lateral direction refers to the direction parallel to the length side of the electron magnetic nica. The so-called permeability anisotropy means that the magnetic permeability in one direction is high and the magnetic permeability in other directions is low. The magnetic permeability direction is oblique, that is, the magnetic permeability is relatively high only in the oblique direction, and the other directions are relatively low, so that the magnetic field generated when the electromagnetic coil is energized is also oblique. In this way, the effectiveness of the magnetic stripe simulation can be improved. When the magnetic head is traversed by the analog magnetic stripe assembly, a strong induced current can be detected at both ends and in the middle portion, thereby improving the success rate of the swipe.

That is, in the first embodiment of the present invention, the main active component is a magnetic core having an anisotropy in the magnetic permeability direction, a positional relationship between the electromagnetic coil and the magnetic core, and a winding manner of the electromagnetic coil, etc. It is not limited. For example, the positional relationship between the electromagnetic wire and the magnetic core may be that the electromagnetic coil is wound on the outer side of the magnetic core, or the magnetic core may be wrapped outside the electromagnetic coil, or the electromagnetic coil and the magnetic core are Included with each other, or, the electromagnetic coil and the core are independent of each other. As shown in Figures 4-1, 4-2, 4-3, and 4-4, the above four positional relationships are shown, wherein the solid line represents the magnetic core and the broken line represents the electromagnetic coil. The winding method of the electromagnetic coil can also be in various ways such as lateral, longitudinal, and oblique directions. For example, Figure 5-1 shows the way of lateral winding and Figure 5-2 shows the way of longitudinal winding.

The core of the magnetic permeability anisotropy may be a magnetic core material directly producing an anisotropy of magnetic permeability to meet the requirements of the first embodiment of the present invention. As shown in 6-1, the direction of the arrow indicates the direction of magnetic permeability of the core material. This core material can be produced in physical or chemical form, or it can be extruded obliquely on a common high magnetic permeability material. The method of machining such as grain is produced. Alternatively, a magnetic permeability anisotropic magnetic core may be prepared using a non-uniformly distributed magnetic powder or the like, and the like.

In addition, in the first embodiment of the present invention, the following manner of simulating the magnetic permeability anisotropy core is also provided: arranging a plurality of soft iron bars obliquely to form a magnetic core material, so as to follow the direction of the soft iron rod The magnetic permeability is relatively high, while the magnetic permeability in other directions is relatively low. Finally, the soft iron rods are arranged together, which is equivalent to forming a magnetic core with an anisotropic magnetic permeability. That is to say, as shown in Figure 6-2, the magnetic core can be composed of a plurality of soft iron rods, each of which is placed obliquely (that is, at a preset angle to the lateral direction), and each soft iron rod is Parallel discharge in the horizontal direction. It should be noted that in the implementation manner as in 6-2, the soft iron rod itself may be isotropic in the magnetic permeability direction, but in this way, the magnetic permeability direction of the magnetic core is along The direction of the soft iron rod. It should also be noted that, as shown in Figure 6-3, the shape of the soft iron rod itself may also be curved, or as shown in Fig. 6-4, or may be a shape connected by oblique angles, and the like.

In summary, in the first embodiment of the present invention, the magnetic core with anisotropic magnetic permeability can enhance the magnetic field strength and change the direction of the magnetic field lines, so that the analog magnetic strip assembly can be produced in a specific direction. Strong magnetic field. In this way, when the magnetic head is passed over the analog magnetic strip assembly, a strong induced current can be detected at both ends and intermediate portions of the analog magnetic strip assembly, thereby increasing the probability of successful card swiping. '

Embodiment 2

In the second embodiment of the present invention, the analog magnetic stripe assembly can be made to generate a strong and stable magnetic field in a specific direction. The analog magnetic strip assembly can be composed of a plurality of obliquely arranged electromagnetic coil groups to make. That is, as shown in FIG. 7, the analog magnetic strip assembly includes a plurality of electromagnetic coils wound by wires, wherein the respective electromagnetic coils are juxtaposed in the lateral direction, and each of the electromagnetic coils is obliquely placed, wherein, Similar to the first embodiment, the oblique direction is 'the direction of the preset angle with the lateral direction; the transverse direction is the direction parallel to the length side of the electronic magnetic stripe card. Through the physical arrangement between the different electromagnetic coils, the magnetic field lines can also be deflected, that is, the analog magnetic stripe assembly can generate an oblique magnetic field after being energized, and in this direction, the magnetic field Both strength and stability are high. Of course, in order to further increase the strength of the magnetic field, each of the electromagnetic coils may also have a magnetic core (as shown in Fig. 7 with a magnetic core), which may be isotropic in the magnetic permeability direction.

Of course, the analog magnetic stripe assembly provided in the second embodiment is also used in an electronic magnetic stripe card. The electronic magnetic stripe card includes a data transmission component, a processor component, and a power supply component in addition to the analog magnetic stripe component.

Embodiment 3

In the third embodiment of the present invention, in order to make the analog magnetic stripe assembly generate a strong and stable magnetic field in a specific direction, the analog magnetic stripe assembly may further include an electromagnetic coil and a magnetic core wound by a wire; wherein, the magnetic The ratio between the length and the width of the core is greater than a preset threshold, and the electromagnetic wire is wound laterally on the outside of the core so that when the solenoid is energized, an oblique magnetic field can be generated. Similarly, the oblique direction herein refers to a direction that is at a preset angle to the lateral direction, and the lateral direction is a direction parallel to the length side of the electronic magnetic stripe card.

That is to say, in order to achieve the purpose of deflecting the magnetic field lines, in addition to the magnetic permeability direction anisotropic core and the oblique arrangement of the electromagnetic coils, the geometric properties of the magnetic core itself can be utilized. As shown in Fig. 8, a laterally wound coil 811 can be used to surround a relatively large core 812. The reason why the magnetic field lines can be deflected is because the magnetic field lines of the magnetic field formed by the energization of the coil 811 are generally not in the strict vertical direction y, but have a small deflection angle with the vertical direction y. This is because the wires of the coil have a certain diameter, so they are not strictly parallel to the X direction when wound. In the absence of a magnetic core, it is assumed that the magnetic field lines generated by the turns are shown by the dotted lines in Figure 9. When the core is added, the strength of the magnetic field increases accordingly. The geometrical properties of the core are relatively large and wide, which means that the core extension in the X direction is longer than that in the y direction, so that the enhancement of the coil magnetic field in the X direction is stronger than that in the y direction. Therefore, the magnetic field generated by the simple coil (shown by the broken line in Fig. 9) is enhanced by the magnetic core 812 to become a new magnetic field having a stronger intensity and a sharp deflection angle (shown by the solid line in Fig. 9).

Similarly, the analog magnetic strip assembly provided in the third embodiment is also applied to an electronic magnetic strip card. In addition to the analog magnetic stripe assembly, the electronic magnetic stripe card also includes a data transmission component, a processor component, and a power component.

In summary, in the above three embodiments provided by the embodiments of the present invention, the magnetic field lines are deflected, so that the entire analog magnetic strip assembly has better stability and reliability, so that the power generation efficiency of the card is improved. Referring to FIG. 10, in the solution provided by the embodiment of the present invention, the average amplitude of the induced current detected by the magnetic head and the relationship between the current direction and the detected position are compared. As can be seen from FIG. 3, the amplitude and direction of the current detected by the magnetic head are The entire magnetic stripe area is relatively stable, which improves the success rate and reliability of the card.

It should be noted that a common electronic magnetic stripe card generally includes a data transmission component, a processor component, a power component, and an analog magnetic stripe component. When a conventional magnetic stripe card needs to be simulated, the data transmission component will continue to be continuously Send a signal to the analog magnetic stripe component. Specifically, the information on the magnetic stripe of the traditional magnetic stripe card stored by the transport processor component is generally a string of characters stored in a binary form, and the data transmission component sends the string of characters as an electrical signal to the analog magnetic The strip component, after sending the string of characters, resends from the beginning and loops. Correspondingly, the analog magnetic stripe component generates a magnetic field based on the received electrical signal. When the card is swiped, the magnetic head can be detected by swiping the analog magnetic stripe assembly. However, since the data transmission component is constantly transmitting signals to the analog magnetic stripe assembly, the analog magnetic stripe component is constantly generating a magnetic field, so that the magnetic field reflected by the analog magnetic stripe component may not be a string when the magnetic head is crossed. At the beginning position, the signal detected by the head may eventually cause a shift deviation.

In order to avoid this, as shown in FIG. 11, in the embodiment of the present invention, the electronic magnetic stripe card 1100 may include, in addition to the data transmission component 1101, the processor component 1102, the power component 1103, and the analog magnetic stripe component 1104, A magnetic strip sensing component 1105 can also be included for sensing the signal of the magnetic head across the analog magnetic strip assembly, passing the signal to the processor component 1102 for controlling the data transfer component 1101 by the processor component 1102. A signal is generated and output to the analog magnetic strip assembly 1104. That is, when the magnetic stripe sensing component 1105 senses that the card is being swiped, the data transfer component 1101 transmits the data that needs to be simulated to the analog magnetic stripe component 1104 for magnetic card simulation. The magnetic strip sensing component 1105 can generally be placed at one or both ends of the analog magnetic strip assembly 1104. When the specific head passes over the magnetic strip sensing component 1105, a signal is sent to the processor component 1102. The processor component 1102 It is known that the user starts to swipe the card, and then controls the analog magnetic stripe component 1104 to generate a signal, ensuring that the magnetic head can receive a continuously stable signal in the middle portion of the analog magnetic stripe, completing a card swipe operation.

In addition, in the embodiment of the present invention, an electronic magnetic stripe card may include multiple analog magnetic strip components for simulating multiple tracks on a conventional magnetic stripe card, and each analog magnetic stripe component corresponds to one track. . Moreover, each of the analog magnetic strip assemblies can be implemented in the manner described in the embodiment of the present invention. Experiments show that when the analog magnetic strip assembly is implemented in the manner of the embodiment of the present invention, multiple analog magnetic strip assemblies are used. The interference between the two is relatively small.

The various embodiments in the present specification are described in a progressive manner, and each embodiment is mainly described as being different from the other embodiments, and the same or similar parts between the various embodiments may be referred to each other. For the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method embodiment.

The electronic magnetic stripe card provided by the present invention has been described in detail above. The principles and embodiments of the present invention have been described using specific examples. The description of the above embodiments is only for helping to understand the method of the present invention and At the same time, there will be changes in the specific embodiments and the scope of application according to the idea of the present invention, and the contents of the present specification should not be construed as the present invention. limits.
