Description

Technical Field

[0001] This utility model relates to the field of smart card technology, and in particular to a smart card with a numeric keypad and a display screen. Background Technology

[0002] Smart cards are plastic cards with embedded microchips. Smart cards can be classified as follows: based on the type of chip they contain and the method of information communication, smart cards can be divided into storage cards and microprocessor cards, as well as contact cards, contactless cards, and dual-interface cards.

[0003] Existing patent CN216118824U discloses a novel smart card. This utility model includes a smart card body, a first fixing hole, a second fixing hole, an identification tag, a pressure-resistant frame, and a voice broadcast device. The pressure-resistant frame is installed inside the smart card body. The front surface of the smart card body has the first fixing hole and the second fixing hole respectively. The identification tag and the voice broadcast device are embedded in the front surface of the smart card body. The first fixing hole is located between the second fixing hole, and the first and second fixing holes are located above the identification tag, which is also located above the voice broadcast device. This novel smart card is easy to carry, has strong pressure resistance, and is convenient for people with visual impairments or weak recognition abilities to use.

[0004] However, while the existing patent CN216118824U is easy to carry, has strong pressure resistance, and is easy for people with poor eyesight and recognition ability to use, it may affect the normal use of the card when the magnetic core end of the card is subjected to electromagnetic interference or is damaged.

[0005] To address this, we propose a smart card with a numeric keypad and a display screen. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a smart card with a numeric keypad and a display screen.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A smart card with a numeric keypad and a display screen includes a base card, a numeric keypad fixedly disposed on the outside of the base card, a display screen fixedly disposed above the numeric keypad, and a control unit fixedly disposed inside the base card.

[0009] As a further embodiment of this utility model: a magnetic card sensing area is fixedly provided on the outside of the base card, the magnetic card sensing area is connected to the display screen, and a storage unit is fixedly provided inside the base card.

[0010] As a further improvement of this utility model: the control unit is signal-connected to the storage unit, and a button battery is fixedly installed inside the base card.

[0011] As a further improvement of this utility model: the button battery is electrically connected to the display screen, and two button batteries are fixedly disposed inside the base card.

[0012] Compared with the prior art, this utility model provides a smart card with a numeric keypad and a display screen, which has the following advantages:

[0013] 1. In this utility model, the magnetic card sensing area can display the information inside the storage unit on the display screen through sensing. When the magnetic card sensing area is interfered with or damaged, the numeric keypad can be used to input the card PIN. When the card PIN is entered correctly, the control unit can also display the information inside the storage unit on the display screen. When the card PIN is entered incorrectly, the control unit cannot display the information inside the storage unit on the display screen.

[0014] 2. In this utility model, the storage unit is used to store card information. According to the power consumption requirements of the control unit, numeric keypad and display screen, a button battery of appropriate capacity is selected, and a button battery holder is installed on the base card to ensure that the positive and negative terminals of the battery are correctly connected. The button battery is used to power the control unit, numeric keypad and display screen, effectively improving the convenience of the card.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0022] Example: A smart card with a numeric keypad and a display screen includes a base card 1, a numeric keypad 2 fixedly disposed on the outside of the base card 1, a display screen 3 fixedly disposed above the numeric keypad 2, and a control unit 4 fixedly disposed inside the base card 1.

[0023] like Figures 1-3 As shown, a magnetic card sensing area 5 is fixedly installed on the outside of the base card 1. The magnetic card sensing area 5 is connected to the display screen 3. A storage unit 6 is fixedly installed inside the base card 1. A control unit 4 is connected to the storage unit 6. A button battery 7 is fixedly installed inside the base card 1. The button battery 7 is electrically connected to the control unit 4, the numeric keypad 2, and the display screen 3. Two button batteries 7 are fixedly installed inside the base card 1. When using a smart card with a numeric keypad and display screen, the magnetic card sensing area 5 can display the information inside the storage unit 6 on the display screen 3 through sensing. When the magnetic card sensing area 5 is interfered with... When both are damaged, the numeric keypad 2 can still be used to input the card key. When the card key is entered correctly, the control unit 4 can also display the information inside the storage unit 6 on the display screen 3. When the card key is entered incorrectly, the control unit 4 cannot display the information inside the storage unit 6 on the display screen 3. The storage unit 6 is used to store card information. Based on the power consumption requirements of the control unit 4, numeric keypad 2, and display screen 3, a button battery 7 of appropriate capacity is selected and installed in the button battery holder on the base card 1, ensuring that the positive and negative terminals of the battery are connected correctly. The button battery 7 is used to power the control unit 4, numeric keypad 2, and display screen 3.

[0024] Working principle: When using a smart card with a numeric keypad and display screen, the magnetic card sensing area 5 can display the information inside the storage unit 6 on the display screen 3 through sensing. When the magnetic card sensing area 5 is interfered with or damaged, the numeric keypad 2 can still be used to input the card PIN. When the card PIN is entered correctly, the control unit 4 can also display the information inside the storage unit 6 on the display screen 3. When the card PIN is entered incorrectly, the control unit 4 cannot display the information inside the storage unit 6 on the display screen 3. The storage unit 6 is used to store card information. According to the power consumption requirements of the control unit 4, numeric keypad 2, and display screen 3, a button battery 7 of appropriate capacity is selected and installed in the button battery holder on the base card 1, ensuring that the positive and negative terminals of the battery are correctly connected. The button battery 7 is used to power the control unit 4, numeric keypad 2, and display screen 3.
