In this document, the term “pulse timing” refers to the time interval from the start of one pulse to the start of the next pulse, and can be used interchangeably with the terms “pulse duration.” .

Referring to FIG. 2A, an electronic device (e.g., the electronic device 100) may transmit an MST signal containing payment information periodically (T) several times (N times) through the MST module. The transmitted first MST signal 200_1 to nth MST signal 200_n may include a pulse indicating 0 or 1, respectively. For example, if the voltage of the pulse does not change for a certain time (t), the time (t) may represent '0', and if the voltage changes (if the phase changes), the section may represent '1'.

According to one embodiment, the MST module may periodically transmit the same MST signal. For example, the MST signal may include payment information included in at least part of the card.

For example, each MST signal, such as the first MST signal 200_1 to the nth MST signal 200_n, may include information included in two or more of track 1, track 2, or track 3 of the card. .

While the MST signals 200 are transmitted, each MST signal 200_1 to 200_n may have a different form. For example, the pulse timing or period (T) may be different for each MST signal.

Referring to FIG. 2B, an electronic device (e.g., the electronic device 100) may transmit an MST signal containing payment information at different pulse timing (t) through the MST module. According to one embodiment, MST signals, for example, the first MST signal 200_1 to the nth MST signal 200_n, may have different pulse timing (t). For example, the first MST signal 200_1 includes information on at least part of track 1, track 2, track 3, or token of the card, and the pulse timing of each pulse thereof may be 300us. The second MST signal 200_2 includes information on at least part of track 1, track 2, track 3, or token of the card, and the pulse timing of each pulse thereof may be 500us. If the pulse timing t is small, an external device (e.g., POS terminal) can receive a signal similar to when the user quickly swipes the card. If the pulse timing t is large, an external device (e.g., POS terminal) can receive a signal similar to when the user slowly swipes the card.

According to one embodiment, the period T may be variable. For example, the first MST signal 200_1 and the second MST signal 200_2 may each include information on at least some of track 1, track 2, track 3, or tokens of the card, and may be transmitted for a certain period of time (e.g. The first MST signal 200_1 and the second MST signal 200_2 may be transmitted once per second. As another example, the third MST signal 200_3 and the fourth MST signal 200_4 may each include information on at least some of track 1, track 2, track 3, or tokens of the card, and may be transmitted for a certain period of time The third MST signal 200_3 and the fourth MST signal 200_4 may be transmitted once every 2 seconds.

An electronic device (e.g., electronic device 100) may transmit a signal including payment data (e.g., track information) periodically (T) (e.g., once per second) using the MST module. For example, a signal transmitted once per second may include information on track 1 (e.g., Figure 3(a)) or information on track 2 (e.g., Figure 3(b)).

According to one embodiment, data, such as “00000000”, may be added to the lead and tail of the binary string in FIG. 4(a). Accordingly, the data in FIG. 5(a) can be generated. Data, such as “00000000”, may be added before and after the binary column in FIG. 4(b). Accordingly, the data in FIG. 5(b) can be generated.

According to one embodiment, an electronic device (e.g., the electronic device 100) may transmit one track information through the MST module during one period (T). This transmission method may be referred to as a simple sequence. For example, the terminal transmits an MST signal containing information on track 1 (e.g., data in FIG. 5(a)) or information on track 2 (e.g., data in FIG. 5(b)) during one period (T). can do. As another example, a plurality of track information may be included and transmitted during one period (T). This transmission method may be referred to as a complex sequence, and embodiments for implementing this are described below.

Figure 6 shows an embodiment in which a plurality of track information is included in the MST signal.

According to one embodiment, referring to FIG. 6(a), the terminal sequentially connects (lumping) the track 1 data 601 of FIG. 5(a) and the track 2 data 602 of FIG. 5(b). It can be composed of one data, and the configured data can be transmitted for one period (T). For example, at least one MST signal among the MST signals 200 of FIG. 2A may include the data of FIG. 6(a).

According to another embodiment, referring to FIG. 6(b), the terminal may configure at least a portion of the MST signal with at least one track data in reverse order. For example, the terminal generates inverted track 1 data 603 by reversing track 1 data 601 in Figure 5(a), and tracks 2 data 602 in Figure 5(b) and the above. The inverted track 1 data 603 can be sequentially concatenated (lumped) to form one data, and the configured data can be transmitted for one period (T). The reverse track 1 data 603 may produce the same result as if the user swiped the card in the opposite direction.

Figure 7 is a diagram showing an example of a simple transmission sequence and a complex transmission sequence according to an embodiment of the present invention.

Referring to FIG. 7 , an electronic device (eg, electronic device 100) may first perform the first simple sequence 710. For example, the electronic device periodically (T ₁ ) transmits the MST signal containing the information of track 2 (e.g., the data in FIG. 5(b)) four times in succession (e.g., once every second (T ₁ )). Number 4) It can be transmitted. Here, the width W ₁ of the MST signal may be determined by the pulse timing of the pulse of the MST signal. For example, the pulse timing of the first simple transmission sequence 710 may be determined to be 300us.

Next, the electronic device may perform the first complex sequence 720. For example, the electronic device periodically (T ₂ ) sequentially connects the information of track 1 and inverted track 2 (e.g., inverted track 2 data consisting of track 1 data 601 and track 2 data 602 in reverse order). An MST signal containing one piece of data can be transmitted four times in succession. The electronic device may reduce the pulse timing of the first complex sequence 720 to make the period T ₂ equal to the period T ₁ . As another example, the electronic device may make the pulse timing of the first complex sequence 720 the same as the pulse timing of the first simple sequence 710. In that case, the amount of information transmitted in period T ₂ becomes more than T ₁ , so the width W ₂ becomes wider than W ₁ . Therefore, if the interval I ₂ and I ₁ are set to be the same, the period T ₂ may be longer than the period T ₁ . However, the electronic device may make the period T ₂ equal to the period T ₁ by making the interval I ₂ narrower than I ₁ .

Next, the electronic device may perform the second simple sequence 730. For example, the electronic device may periodically transmit an MST signal including information on track ₂ (e.g., data in FIG. 5(b)) four times in succession. At this time, the pulse timing may be longer than the pulse timing of the first simple sequence 710. For example, if the pulse timing of the first simple sequence 710 is 300us, the pulse timing of the second simple sequence 730 may be 500us.

Next, the electronic device may perform the second complex sequence 740. For example, the electronic device periodically (T ₄ ) sequentially connects the information of track 1 and reverse track 2 (e.g., data consisting of the data in FIG. 5(a) and the data in FIG. 5(b) in reverse order). An MST signal containing data can be transmitted four times in succession. At this time, the pulse timing may be longer than the pulse timing of the first complex sequence 720. For example, if the pulse timing of the first complex sequence 720 is 300us, the pulse timing of the second complex sequence 740 may be 500us.

According to various embodiments of the present invention, an electronic device (e.g., MST control module 130 of the electronic device 100) may adjust pulse timing. As another example, an electronic device (e.g., MST control module 130 of the electronic device 100) may perform periodic adjustment of the MST signal. As another example, an electronic device may perform a simple sequence. As another example, an electronic device may perform a complex sequence. As another example, an electronic device can perform a combination of simple sequences and complex sequences. For example, as shown in FIG. 7, the electronic device can generate a total of 16 MST signals for 20 seconds by combining a simple sequence and a complex sequence. Here, the number of occurrences and time “16 times, 20 seconds” are design changes and do not limit the technical idea of the present invention. The MST signal may have characteristics different from other MST signals in at least one of the type of data included therein, period, and pulse timing. For example, an MST signal may have a signal transmission period of 1 second, and other MST signals may have a value other than 1 second.

The MST signal may be changed and transmitted depending on the terminal situation. For example, according to one embodiment, the electronic device acquires location information (e.g., country code, IP address, GPS information, etc.), uses this to recognize the location of the electronic device, and sends a signal corresponding to the recognized location. Occurrence conditions (e.g. sequence combination, period, pulse timing) can be determined. For example, a condition table is previously stored in the memory of the electronic device, and the processor can check the condition corresponding to the recognized position in the condition table. The electronic device may generate an MST signal based on determined conditions. According to another embodiment, the electronic device may check the remaining battery capacity or the heat status of the battery. In cases where battery consumption is high or heat is excessive, a simple sequence may be transmitted preferentially. According to another embodiment, the electronic device may transmit the MST signal by changing at least one of the transmission period, pulse timing, or sequence depending on the cellular communication method. For example, when GSM is implemented in an electronic device, the electronic device may adjust the transmission cycle of the MST signal so as not to be affected by the TDMA cycle.

The MST signal may be changed and transmitted by an external device located near the terminal. For example, the electronic device (user terminal) receives characteristics of the POS terminal related to, for example, track, transmission cycle, etc. from a beacon terminal installed in a store, and based on this, at least one of the transmission cycle, pulse timing, or sequence. You can adjust one.

A signal 812 may be transmitted. According to another embodiment, the MST data transmission module 810 may transmit data in differential form with different phases. According to another embodiment, the MST data transmission module 810 divides track 1, track 2, or track 3 data included in the magnetic card by time and sequentially transmits them, or interleaves each data and transmits it. You may. As another example, the MST data transmission module 210 may transmit at least part of track 1, track 2, or track 3 data by reversing it (e.g., changing 11110101 to 10101111 by changing the order). As another example, the MST data transmission module 810 may sequentially transmit the first simple sequence 710, the first complex sequence 720, the first simple sequence 730, and the second complex sequence 740 of FIG. 7. It may be possible.

According to one embodiment, the data reception module 822 of the MST control module 820 may recognize the low/high state of the transmitted pulse as data (eg, 0 or 1 bit). Alternatively, the number of low/high transitions during a specified time can be checked and recognized as data. For example, if low/high conversion occurs once during a specified time, it can be recognized as 0 (zero) bit, and if it occurs twice, it can be recognized as 1 (one) bit.

For example, in the case of Zero bit, the data reception module 822 can turn on the first and fourth switches, and turn on the second and third switches. Or it may work the other way around. In the case of one bit, the data reception module 822 can turn off the first and fourth switches and turn on the second and third switches. Or it may work the other way around. The output conversion module 821 changes the direction of the voltage (direction of the current) supplied to both ends of the coil antenna (L) according to the data recognized by the data reception module 822, and sends it to an external device (e.g. The direction of the magnetic field transmitted to the POS terminal can be changed. For example, in the case of zero bit, the voltage level applied to the coil antenna 831 may be Vm and the direction of current may be in the A direction. In the case of one bit, the voltage level applied to the coil antenna 831 is Vm and the direction of current may be in the B direction opposite to A. The magnetic field generated from the coil antenna may be similar to the magnetic field generated when a magnetic card is swiped on a POS terminal. The switches S1, S2, S3, and S4 may include at least one of an N-type transistor (eg, a metal oxide semiconductor field effect transistor (MOSFET)), a P-type transistor, or a relay.

FIG. 18(a) shows the rear of the electronic device, FIG. 18(b) shows internal components placed below the rear, and FIG. 18(c) shows the rear and internal components together.

Referring to (a) of FIG. 18, the cover 1810 may constitute the back of the electronic device and may be made of a conductive material, and an upper region 1813 is formed by an upper slit 1811 and a lower slit 1812. It can be divided into a central area 1814 and a lower area 1815.

Referring to (b) and (c) of FIG. 18, a loop antenna 1850 (e.g., loop antenna 1120 of FIG. 11) may be placed under the cover 1810. One end of the loop antenna 1850 may extend adjacent to the upper slit 1811, and the other end may extend adjacent to the lower slit 1725.

Additionally, the upper area 1813 may operate as another antenna (e.g., NFC antenna) by being electrically connected to the feeding coil 1824 through the third feeding point 1823 formed on the first substrate 1820.

Figure 19 shows an electronic device with a solenoid-type loop antenna, according to various embodiments of the present invention. Figure 19 (a) shows the rear of the electronic device, Figure 19 (b) shows internal components arranged below the rear, and Figure 19 (c) shows the rear and internal components together.

Referring to (a) of FIG. 19, the cover 1920 may form the back of the electronic device and may be made of a conductive material. The cover 1920 may have an opening 1926 through which an optical sensor (camera, PPG sensor, etc.) can be placed, and the upper slit 1924 and the lower slit 1925 form an upper region 1921, a central It can be divided into a region 1922 and a lower region 1923. The upper slit 1924 extends a certain length toward the bottom of the cover 1920, that is, toward the opening 1926, and as shown, its shape may be a “T” shape. Symmetrically, the lower slit 1925 extends a certain length toward the top of the cover 1920, so its shape may also be a “T” shape. The upper area 1921 and the central area 1922 may be electrically connected by a first connection part 1927, and the central area 1922 and the lower area 1923 may be electrically connected by a second connection part 1928. there is.

Referring to (b) and (c) of FIGS. 19, the loop antenna 1931 (e.g., the loop antenna 1120 of FIG. 11) may be disposed between the upper slit 1924 and the lower slit 1925, and A magnetic field can be formed in the axial direction. Accordingly, the magnetic flux generated by the loop antenna 1931 may propagate to the upper slit 1924 or the lower slit 1925 and be radiated outside the terminal. A battery (not shown) may be located below the loop antenna 1931.

The length of the loop antenna 1931 may be shorter than the distance between the upper slit 1924 and the lower slit 1925. Then, eddy currents may be generated in the cover 1920 or internal conductive parts, and the radiation efficiency may be lower than the desired standard value. Accordingly, the first metal plate 1932 or the second metal plate 1933 may be attached adjacent to (or in contact with) both ends of the loop antenna 1931, respectively, and thus, the generation of vortices can be reduced. and the magnetic flux can be smoothly propagated toward the slit. The first metal plate 1932 or the second metal plate 1933 can be used as a radiator for other communication methods. For example, the loop antenna 1931 can be used as a radiator for MST by combining with the first metal plate 1932 and the second metal plate 1933. The first metal plate 1932 or the second metal plate 1933 can be used as a radiator for NFC or WPC (wireless charging). That is, the first metal plate 1932 and the second metal plate 1933 may be disposed adjacent to the upper slit 1924 and the lower slit 1925, respectively, and accordingly, the first metal plate 1932 or the second metal plate 1933 may be disposed adjacent to the upper slit 1924 and the lower slit 1925, respectively. 2 The magnetic flux generated in the metal plate 1933 may be radiated outward through the upper slit 1924 or the lower slit 1925.

In the loop antenna 1931, the metal plate (e.g., core 1124b in FIG. 11) may have a different permeability from the first metal plate 1931 and the second metal plate 1933. The first metal plate 1931 and the second metal plate 1933 may also have different permeability. For example, the metal plate of the loop antenna 1931 may be for MST, the first metal plate 1932 may be for NFC, and the third metal plate 1933 may be for WPC, and if so, each may have a different operating frequency (e.g. NFC is 13.56MHz, WPC is 100KHz~205KHz, MST is 100KHz or less), and the permeability of metal plates may vary accordingly. Of course, even if their uses are different, the first metal plate 1932 and the second metal plate 1933 propagate the magnetic flux propagated from the loop antenna 1931 to the upper slit 1924 or the lower slit 1925 to achieve MST performance can be improved.

The portion below the lower slit 1925 in the cover 1920 can be used as an antenna. For example, the left portion of the second connection portion 1928 may operate as the first antenna 1941, and the right portion may operate as the second antenna 1942.

The first antenna 1941 and the second antenna 1942 can operate as main antennas that transmit and receive signals. The frequency supported by the first antenna 1941 may be higher than the frequency supported by the second antenna 1942. For example, the first antenna (1941) can support 1.6 GHz to 5 GHz, and the second antenna (1942) can support 600 MHz to 2 GHz.

The upper part of the upper slit 1924 in the cover 1920 can be used as an antenna. For example, the right portion of the first connector 1927 may operate as the third antenna 1943, and the left portion may operate as the fourth antenna 1944. The third antenna 1943 and the fourth antenna 1944 may be electrically connected to the first substrate 1950, respectively, and the third feeding point 1951 and the fourth feeding point disposed on the first substrate 1950 A signal can be received and radiated from a communication circuit through (1952), and a wireless signal can be received and transmitted to the circuit through the third feeding point (1921) and the fourth feeding point (1952). The third antenna 1943 and the fourth antenna 1944 may operate as diversity antennas for receiving signals. The frequency supported by the third antenna 1943 may be higher than the frequency supported by the fourth antenna 1944. For example, the third antenna (1943) can support 1.6 GHz to 5 GHz, and the fourth antenna (1944) can support 600 MHz to 2 GHz.

The first connection part 1927 and the second connection part 1928 may be arranged opposite to each other based on the X-axis. The first antenna (1941), the third antenna (1943), the second antenna (1942), and the fourth antenna (1944), which support similar frequencies, are located diagonally to increase the isolation between the antennas and signal Correlation in transmission and reception can be lowered.

In the cover 1920, the central area 1922 between the slits may be electrically connected to the ground 1953 of the first substrate 1950. To prevent electric shock, ground 1953 may be connected to the central area 1922 through a capacitor. Through grounding (1953), the performance of the antenna can be improved and the noise shielding effect can be increased.

The heights of the first substrate 1950 and the second substrate 1960 may be different. The first substrate 1950 and the second substrate 1960 may be connected to the FPCB 1970. The second substrate 1960 is disposed at a lower position than the first substrate 1950, and the distance between the second substrate 1960 and the first and second antennas 1941 and 1942 on the Z axis is equal to the distance between the first substrate 1950 and the first antenna 1941 and 1942. and 2 antennas (1941, 1942). By increasing the distance between the second substrate 1960 and the first and second antennas 1941 and 1942, the performance of the first and second antennas 1941 and 1942 can be improved. The circuit of the first board 1950 and the power supply module of the second board 1960 may be connected through a coaxial line.

Figure 27 illustrates a payment user interface of an electronic device, according to various embodiments.

According to one embodiment, an electronic device (eg, electronic device 11) may receive a user input and execute a payment application. For example, the electronic device may execute a payment application (e.g., Samsung Pay) in response to the user input 2730 (e.g., sweep from the bezel area 2710 in the direction of the display 2720). Additionally, the electronic device may display a card image 2740 corresponding to at least one of cards already registered in the electronic device through the display 2720 in response to the user input 2730.

According to one embodiment, the electronic device may select a card to be used for payment from among a plurality of pre-registered cards in response to a user input. For example, the electronic device may select a card to be used for payment in response to a user input 2750 (e.g., left or right scrolling) and display a card image 2760 corresponding thereto. The electronic device may request authentication from the user for payment using the selected card. The authentication method may use, for example, the user's biometric information. For example, the electronic device may perform a payment operation by scanning the user's fingerprint 2770 through a fingerprint detection module. For example, when user authentication is completed through the fingerprint detection module, the electronic device may perform a simple sequence (e.g., transmitting an MST signal containing information in track 2 several times).

According to one embodiment, user authentication may be performed again in order to re-perform the payment operation. For example, when user authentication is completed again after a certain period of time, the electronic device may transmit the MST signal again, but change the method. For example, electronic devices can change period or pulse timing. Additionally, the information included in the MST signal can be changed to information according to a complex sequence. According to another embodiment, in order to re-perform the payment operation, the user can place the terminal on the reader and tag it again. The user's tagging behavior may be recognized through various sensors (e.g., acceleration sensor 103, gyro sensor 105, proximity sensor, HRM (heart rate monitor) sensor, etc.) provided in the electronic device. In response to the tagging operation, the electronic device may transmit the MST signal by changing at least one of the transmission period, pulse timing, or sequence of the MST signal. Each time a user performs a tagging operation, the electronic device may transmit the MST signal by changing at least one of the transmission period, pulse timing, or sequence of the MST signal.

According to one embodiment, when user authentication is completed, the electronic device may transmit NFC and MST signals simultaneously or sequentially. For example, a processor (e.g., 150) in an electronic device controls an NFC control module (e.g., 140) and an MST control module (e.g., 130) to activate the NFC module (e.g., 120) to detect a card reading device. (e.g., setting the NFC module to polling mode), and at the same time, generating an MST signal can be performed through the MST module (e.g., 110). The processor can check whether a signal (e.g., ping) has been received from the card reading device through the NFC module, and if a ping has been received as a result of the confirmation, the processor can stop the operation of the MST module. Additionally, the processor may provide card information for payment to a card reading device (eg, NFC reader) through the NFC module. If the ping is not received as a result of the confirmation, the processor may control the MST control module to generate an MST signal with payment information.

According to one embodiment, when payment is completed, the user may press a button (eg, home button 2780) on the electronic device to close the payment application. When payment is completed, the electronic device (user terminal) may recognize this and accordingly, for example, stop generating the MST signal. For example, when the card company confirms the payment, it notifies the user terminal through the network and the user terminal can stop generating the MST signal.

The first antenna 3130 and the second antenna 3140 may be different types of antennas. For example, one of the antennas may be a planar type antenna (e.g., the first loop antenna 1020), and the other may be a solenoid type antenna (e.g., the second loop antenna 1120). Additionally, when the MST module has a solenoid-type antenna, the MST module may be protected with a housing at least partially made of a non-conductive material (eg, a housing with a cover 1113).

According to one embodiment, the first antenna 3130 and the second antenna 3140 may transmit the same MST signal. Referring to FIG. 31A, a first electrode 3111 and a second electrode 3112 are formed in the driving unit 3110, and the connection unit 3120 connects the first electrode 3111 to the first antenna 3130 and the second antenna. Each can be electrically connected to 3140, and the second electrode 3112 can be electrically connected to the first antenna 3130 and the second antenna 3140, respectively. The first antenna 3130 and the second antenna 3140 each receive current from the first electrode 3111 or the second electrode 3112 through the connection portion 3120, and form a magnetic field by the supplied current. , a magnetic field signal (MST signal) of a specific frequency can be radiated to the outside. For example, the first antenna 3130 and the second antenna 3140 may receive the sequences of FIG. 7 from the driver 3110 through the connection unit 3120, convert them into RF signals, and sequentially transmit them.

According to another embodiment, the first antenna 3130 and the second antenna 3140 may transmit different MST signals.

Figure 32 schematically shows a loop antenna according to various embodiments of the present invention.

According to one embodiment, the loop antenna 3200 (e.g., loop antenna 1020) may be designed so that the magnetic field strength is different for each region. Accordingly, the location of the null point of the loop antenna occurring within the terminal may be moved. For example, the width of the antenna pattern (e.g., coil) of the first part 3210 may be implemented to be wider than that of the antenna pattern of the second part 3220. Accordingly, when current flows, the resistance of the first part 3210 is relatively lower than that of the second part 3220, and therefore, the strength of the magnetic field generated in the first part 3210 is generated in the second part 3220. It can be stronger than the strength of the magnetic field. If the strength of the magnetic field generated in the first part 3210 is stronger than the strength of the magnetic field generated in the second part 3220, the shaded area of the loop antenna 3200 is not the center 3230 of the terminal, but the lower part 3240. ) can be formed. In other words, if the width of the antenna pattern of the first part 3210 and the width of the antenna pattern of the second part 3220 are the same, the shaded area may be the center 3230 of the terminal. If the width of the antenna pattern of the first part 3210 is wider than the width of the antenna pattern of the second part 3220, the shaded area may be the lower part 3240 of the terminal. For example, as shown in FIG. 22, while payment is in progress, the electronic device (e.g., electronic device 100) recognizes the MST recognition range (e.g., the area between the center and the top of the terminal corresponding to box 2230). ') and thereby allowing the user to bring the MST recognition range closer to the leader, thereby improving the recognition rate of the MST.

Figures 33A to 33G schematically show the structure of a loop antenna according to various embodiments of the present invention.

According to one embodiment, as shown in FIG. 33A, the loop antenna 3310 (e.g., loop antenna 1020) has a first path 3311 on top of a terminal (e.g., a smart phone), and a second path. It may be designed so that 3312 is formed in the center and the third path 3313 is formed at the bottom. Additionally, the loop antenna 3310 may be designed so that the direction 3311a of the current flowing through the first path 3311 is the same as the direction 3312a of the current flowing through the second path 3312. Then, the direction 3311a of the current in the first path 3311 may be opposite to the direction 3313a of the current flowing in the third path 3313. Accordingly, when the loop antenna 3310 forms a magnetic field by the current supplied from the communication module 3315 (e.g., MST module 110), the strength becomes stronger at the top and center rather than at the bottom, forming a shadow area 3314. may be formed around the lower portion.

According to another embodiment, referring to FIG. 33B, the loop antenna 3320 (e.g., the loop antenna 1020) has the direction 3323a of the current flowing through the third path 3323 flowing through the second path 3322. It can be designed to be the same as the direction of current 3322a. Then, the directions 3323a and 3322a may be opposite to the direction 3321a of the current flowing through the first path 3321. Accordingly, a shaded area 3325 may be formed around the top of the terminal.

According to another embodiment, referring to FIG. 33C, the paths of the loop antenna 3330 (e.g., loop antenna 1020) connected to the communication module 3332 (e.g., MST module) are in a “B” shape (i.e. , If you draw the current flow, it may be in the shape of a 'B'), and the directions of the currents in the center (3331) may be opposite to each other. Accordingly, the center 3331 may be a shaded area. For example, the loop antenna 3330 in the shape of a 'B' is distributed to both sides (upper and lower) compared to the loop antenna 2100 of FIG. 21. It can have an effect.

According to another embodiment, referring to FIG. 33D, the paths of the loop antenna 3340 (e.g., loop antenna 1020) connected to the communication module 3342 (e.g., MST module) may be in the shape of an “8”. In the center 3341, the currents may have the same direction. Accordingly, the center (3341) may have the strongest magnetic field. The upper part 3343 and the lower part 3344 may be shaded areas.

In addition to the above structures, the loop antenna may be designed to have various structures, such as “B” shaped paths as shown in FIGS. 33E, 33F, and 33G. In these drawings, arrows indicate the direction of current, and places 3350, 3360, and 3370 where the current direction is opposite to each other may be shaded areas.

According to examining the structure of the loop antenna with reference to FIGS. 33A to 33G, the shaded area may vary depending on the location of current paths and the direction of the current in the loop antenna. Therefore, when designing an antenna to increase the MST recognition rate, the location of the shaded area may be considered to increase the MST recognition rate.

34A and 34B schematically show the structure of a loop antenna according to various embodiments.

The loop antenna shown in FIG. 34A can be applied to, for example, the antenna 2430 in FIG. 24B. The first path 3411 forming the outside of the loop antenna 3410 is composed of a planar type coil (e.g., the loop antenna 1020), and the second path 3412 forming the relatively inside is a solenoid coil ( For example, it may be configured as a loop antenna 1120). The flat coil may, for example, be wound without overlap in the XY plane. The solenoid coil may be wound multiple times in the Z-axis direction. Additionally, the solenoid coil may be wound several times in the direction perpendicular to the Z-axis, as shown in FIG. 34b. By varying the number of turns of the coil placed in each section and the area where the coil is placed, the shaded area moves from the center of the loop antenna to the outskirts, and a greater amount of magnetic flux can be radiated in the second path 3412. there is.

The other ends of the two antennas 3512 may be connected to the second electrode 3522, respectively. The first antenna 3511 and the second antenna 3512 may be implemented in different layers of the FPCB. For example, based on the shown Z-axis, the first antenna 3511 may be formed on the bottom layer of the FPCB, and the second antenna 3512 may be formed on the top layer of the FPCB. Loop antennas may be formed on the same layer as each other. For example, referring to FIG. 35B, the first antenna 3531 may be formed at the upper part 3541 on the XY plane, and the second antenna 3532 may be formed at the lower part 3542.

36A and 36B schematically show a plurality of loop antennas according to various embodiments.

Referring to FIG. 36A, a plurality of coil antennas, for example, a first antenna 3611 and a second antenna 3612, may be formed on the same plane (XY plane). According to one embodiment, the loop antenna for MST can be manufactured in various forms to improve the recognition of magnetic fields transmitted to external devices (eg, POS terminals). For example, the paths may be in the shape of an “8” as shown in FIG. 22D or in the shape of a “B” as shown in FIG. 22C. When an electronic device is close to an external device (e.g. POS terminal), it is possible to form current paths perpendicular to the direction in which the magnetic card is swiped on the external device (e.g. POS terminal) as much as possible. It may be in the form. The first antenna 3611 and the second antenna 3612 may each transmit different MST signals. For example, the first antenna 3611 may transmit some of the sequences of FIG. 7 as the first antenna 2530 of FIG. 25B, and the second antenna 3612 may transmit some of the sequences as the second antenna 2540 of FIG. 25B. This allows other parts of the sequences in FIG. 7 to be transmitted.

Referring to Figure 36b, coil antennas may be formed on different planes and based on different axes. For example, the first coil antenna 3621 may form a loop around the x-axis, and the second coil antenna 3622 may form a loop around the y-axis. A shielding layer (not shown) may be positioned between the first coil antenna 3621 and the second coil antenna 3622 to eliminate interference between them.

According to one embodiment, the first coil antenna 3621 or the second coil antenna 3622 may be an FPCB antenna. A loop can be formed in a stacked form by connecting patterns to an FPCB composed of multiple layers.

According to another embodiment, the first coil antenna 3621 or the second coil antenna 3622 may form a loop that surrounds at least a portion of the housing of the electronic device. One part of the coil antenna may be located under the front display of the terminal, and the other part of the coil antenna may be located under the rear cover of the terminal. The coil antenna may be in the form of an FPCB, or may use at least part of the exterior of the terminal.

Figures 37 to 39 show hardware block diagrams inside an electronic device including a plurality of MST modules according to various embodiments of the present invention.

Referring to FIG. 37 according to one embodiment, the first MST module 3710 and the second MST module 3720 may transmit the same data to an external device. The first MST module 3710 and the second MST module 3720 may include coil antennas of different types. The first MST module 3710 and the second MST module 3720 may be positioned spaced apart from each other. The voltage or current delivered to the first MST module 3710 and the second MST module 3720 may be at different levels. The first data reception module 3731 and the second data reception module 3732 within the MST control module 3730 may receive at least one same signal from the MST data transmission module 3740. For example, the MST data transmission module 3740 may transmit the MST signal 3751 (e.g., the data in FIG. 25) containing the same payment information to the first data reception module 3731 and the second data module 3732. there is. In addition, the MST data transmission module 3740 provides a control signal to the first data reception module 3731 and the second data reception module 3732 to activate the first MST module 3710 and the second MST module 3720. 3752) can be transmitted in the same way.

The second MST module 3820 may then be activated to sequentially transmit sequences (e.g., 730, 740).

According to one embodiment, the first MST module 3810 and the second MST module 3820 may be activated alternately to transmit an MST signal to an external device (eg, POS terminal). For example, the first MST module 3810 may be activated first to transmit a sequence (e.g., 710), and then the second MST module 3820 may be activated to transmit a sequence (e.g., 720). Next, the first MST module 3810 is activated again to transmit a sequence (e.g., 730), and then the second MST module 3820 is reactivated to transmit a sequence (e.g., 740).

The first MST module 3810 and the second MST module 3820 may be selectively activated depending on the status of the terminal. For example, when short-range wireless communication (e.g., NFC communication) is activated in the terminal using a loop antenna adjacent to the first MST module 3810, or when cellular network wireless communication is activated using an adjacent antenna, MST The control module 3830 can transmit an MST signal by activating the second MST module 3820. For example, when the MST signal is transmitted by activating at least one of the first MST module 3810 and the second MST module 3820, it is not recognized well, and the user moves the terminal and wants to recognize it again (e.g. : When the user terminal is displayed on the POS terminal and re-tagging), this can be recognized by a sensor, and the first MST module 3810 and the second MST module 3820 can be activated at the same time. For example, when the display mode of the terminal is portrait mode, the second MST module 3820 (e.g., the second coil antenna 3622 in Figure 36b) may be activated, and landscape mode may be activated. ), the first MST module 3810 (e.g., the first coil antenna 3621 in FIG. 36B) may be activated.

The same control signal (D) may be transmitted, and MST signals (E, F) containing different payment information may be transmitted to the first data reception module 3831 and the second data reception module 3832. For example, track 1 and track 2 information may be transmitted to the first data reception module 3831 and the second data reception module 3832, respectively. The MST signal including track 1 information is transmitted to the first MST module 3810 through the first output conversion module 3851, and thereby can be transmitted to the outside.

FIG. 44 is a diagram schematically illustrating a plurality of coil antennas in an electronic device according to various embodiments of the present invention, and showing the strength of a magnetic field generated from the plurality of coil antennas and a shaded area.

Referring to FIG. 44(a), an electronic device (e.g., electronic device 11) according to various embodiments of the present invention includes a first coil antenna 4411 and a second coil antenna 4412, and the current Depending on the power supply, the first coil antenna 4411 and the second coil antenna 4412 may each form a magnetic field. Figure 44(b) shows the strength of the magnetic field (recognized by an external device (POS terminal)) generated from the first coil antenna 4411 according to various embodiments of the present invention and the location of the shaded area (null point) . Additionally, Figure 44(c) shows the strength of the magnetic field generated from the second coil antenna 4412 and the location of the shaded area according to various embodiments of the present invention.

According to FIG. 44(b), the first shaded area 4421 generated by the first coil antenna 4411 and the first shaded area 4422 generated by the second coil antenna 4412 overlap each other. ) may not work. The first coil antenna 4411 and the second coil antenna 4412 may transmit MST signals periodically and alternately. For example, the first coil antenna 4411 and the second coil antenna 4412 can transmit the MST signal to the outside once every second a total of 16 times (i.e., 8 times each). Accordingly, the shaded areas may also alternate periodically. For example, the shaded area may be periodically changed from the first shaded area 4421 to the second shaded area 4422 or vice versa. At this time, when an external device (e.g., POS terminal) is located in the first shaded area 4421, the external device (POS terminal) does not receive payment information from the first coil antenna 4411, or even if payment information is received, the external device (POS terminal) does not receive payment information. There may be cases where recognition is not possible. Payment may be completed by receiving payment information (MST signal) from the second coil antenna 4412 of an external device (e.g., POS terminal). As described with reference to FIG. 44, the electronic device can increase the payment success rate by sequentially operating a plurality of coil antennas in alternating shaded areas.

For example, referring to FIG. 45A, the first coil antenna 4511 may be formed on the left side of the electronic device (eg, a smart phone) and the second coil antenna 4512 may be formed on the right side. Current may be supplied to the first coil antenna 4511 and the second coil antenna 4512 at the same time. At this time, the direction of the current may be different. For example, the path of the first coil antenna 4511 may form a clockwise direction, and the path of the second coil antenna 4512 may form a counterclockwise direction. Accordingly, as shown, the direction of the current is the same at the center, so the magnetic field strength is greatest, and a shaded area may be created around it. For example, two shaded areas 4513 and 4514 may be formed on both sides of the center.

Referring to Figure 45b, the directions of the currents may be the same. Accordingly, as shown, the direction of the current changes at the center, so the strength of the magnetic field may be the weakest. That is, when the first coil antenna 4511 and the second coil antenna 4512 are arranged as shown, if the directions of current are the same, the area adjacent to each other (i.e., the center) is the shaded area 4515. You can.

You can. In other words, the electronic device can increase the success rate of payment by simultaneously operating a plurality of coil antennas in alternating shaded areas and changing the direction of the current.

Meanwhile, the electronic device uses both a method of sequentially operating a plurality of coil antennas (see FIG. 44) and a method of operating a plurality of coil antennas simultaneously but changing the direction of the current (see FIG. 45), all of which are used to create a shadow area. can be changed, and this can have the effect of increasing the success rate of payment.

When the track (i.e., magnetic black line) of a magnetic card is swiped at the position of the header on the rail of the card reader, it passes through the coil connected to the header. Magnetic flux can be varied. A current corresponding to the change in magnetic flux is generated in the card reading device, and the card reading device can read and process data recorded in the track from this current.

The electronic device stores data recorded in tracks of a magnetic card and may be equipped with a module for magnetic field communication, such as an MST module. The MST module can load the data contained in the tracks into a magnetic field signal and transmit it to the card reading device through an antenna. Then, the same current as when the magnetic card is swiped at the position of the header of the card reading device can be generated in the card reading device. That is, the user can pay expenses by bringing the electronic device close to or in contact with the card reading device.

Figures 48A and 48B are diagrams for explaining data transmission methods according to various embodiments of the present invention.

Data transmitted in the MST signal by the MST module may be transmitted in the form of a token, as shown in FIG. 48A. In a payment method using tokens, at least some of the data in tracks 1, 2, and 3, rather than tracks 1, 2, and 3, may be replaced with tokens or cryptograms. For example, referring to Figure 48b, PAN can be replaced with Token in tracks 1, 2, and 3. ADDITIONAL DATA and DISCRETIONARY DATA in tracks 1 and 2 and USE AND SECURITY DATA and ADDITIONAL DATA in track 3 can be replaced with Cryptogram. The replaced value can be converted to bits and transmitted to the card reading device in the MST signal.
