At the same time, the second magnetic communication unit 4 can obtain the magnetic field change curve to form dynamic verification information in the processing unit, that is, multiple card swipings are used to record the cardholder's card swiping habits, so as to determine whether the card is swiped by the cardholder, thereby improving the security of the card swiping. In addition, the second magnetic communication unit 4 and the third magnetic communication unit 5 complete the positioning of the communication card 10, and cooperate with the position adjustment unit 7 to realize radio frequency communication of the communication card 10 by the radio frequency communication unit 6. During the entire card swiping process, the first magnetic communication unit 3 completes the reading and writing of the magnetic track 101 on the front of the communication card 10, and the second magnetic communication unit 4 and the third magnetic communication unit 5 complete the reading and writing of the magnetic track 101 on the back of the communication card 10, realizing the combination of double-sided card swiping and multi-communication mode card swiping, improving the security of the card swiping, and optimizing the card swiping operation, so that the card can be swiped faster and more conveniently.

[0050] In at least one embodiment, see Figure 7 The first magnetic communication unit 3 includes: a first magnetic head reader 31; the first magnetic head reader 31 is installed on the first card swiping rack 1, the first magnetic head reader 31 is set towards the card swiping channel, and the first magnetic head reader 31 is electrically connected to the processing unit; when the communication card 10 enters the card swiping channel and moves along the card swiping direction and the first magnetic head reader 31 senses the magnetic track 101 on the front of the communication card 10 for the first time, the first magnetic head reader 31 obtains the first sensing time point; when the communication card 10 moves in the card swiping channel, the first magnetic head reader 31 reads and writes the magnetic track 101 on the front of the communication card 10.

[0051] Specifically, the function of the first magnetic head reader 31 is to sense the track 101 on the front of the communication card 10 and complete the read and write operations. At the same time, after obtaining the first sensing time point, it can send the sensing signal to the processing unit in time to provide the processing unit with a basis for calculating the card swiping speed.

[0052] In at least one embodiment, see Figure 8The second magnetic communication unit 4 includes: a second magnetic head reader 41; the second magnetic head reader 41 is installed on the position adjustment unit 7, the second magnetic head reader 41 is set towards the card swiping channel, and the second magnetic head reader 41 is electrically connected to the processing unit; when the communication card 10 enters the card swiping channel and moves in the card swiping direction and the second magnetic head reader 41 senses the track 101 on the back of the communication card 10 for the first time, the second magnetic head reader 41 obtains the second sensing time point; when the communication card 10 moves from the second When the magnetic head reader 41 moves toward the third magnetic communication unit 5, the second magnetic head reader 41 obtains the magnetic field change curve; when the second magnetic head reader 41 first senses the first positioning position point on the track 101 on the back of the communication card 10, the second magnetic head reader 41 sends a sensing signal of the first positioning position point to the processing unit; after the second magnetic head reader 41 senses the track 101 on the back of the communication card 10, the second magnetic head reader 41 reads and writes the track 101 on the back of the communication card 10.
