S4: and (5) carrying out milling groove packaging on the card.
Specifically, as shown in fig. 2, the visible card comprises a middle metal shell 1 and two metal printing sheets 2. In the process of manufacturing the middle metal shell 1, a piece of metal sheet 101 is firstly taken, and the metal sheet 101 can be steel or aluminum. Coating insulating materials on the upper and lower surfaces of the metal sheet 101, wherein the insulating materials are insulating glue; a die is used to press the surface of the metal sheet 101 to form a slot for mounting an electronic module. Punching is carried out in the slot position area, and the punching position corresponds to the position of each component on the electronic module; the components on the electronic module at least comprise keys, a chip, a display and a battery. The resulting intermediate metal shell 1 is shown in fig. 3, and the thickness of the intermediate metal shell 1 is 0.5mm. One metal sheet 101 may be die cut to form a plurality of intermediate metal shells 1, which may be mass-produced.
In the production of the metal printing sheet 2, a metal sheet 101 is first taken, and the metal sheet 101 may be steel or aluminum. The metal sheet 101 is subjected to personalization, wherein the personalization refers to printing trademark patterns and/or marks such as digital serial numbers on the surface of the metal sheet 101 in the area where the window 201 is not displayed according to the needs of customers. If the trademark pattern and the digital serial number are printed, the trademark pattern and the digital serial number are arranged for the attractive appearance of the card, and at least the trademark pattern and the digital serial number are not overlapped. The personalized metal sheet 101 is punched with a die to punch the display window 201 on the metal sheet 101, and after punching, the surface of the metal sheet 101 is coated with an adhesive and covered with a transparent film, wherein the transparent film is a transparent laser film and has an insulation function.

After the isolation and insulation treatment is carried out on each device of the electronic module, the upper surface and the lower surface of the middle material metal shell 1 are respectively covered with a metal printing sheet 2, so that the display 5 in the electronic module is positioned in the display window 201. Of course, the size of the metal printed sheet 2 is identical to the size of the intermediate metal shell 1. After the positions of the metal printing sheet 2 and the middle metal shell 1 are adjusted, lamination is carried out under the environment of the pressure range of 2Mpa to 4Mpa, and then solidification is carried out for 24 hours under the environment of the temperature of 40 ℃ to form the metal visible card, as shown in figure 5. The metal visual card is a non-contact card, and the non-contact card is obtained through an antenna chip in the card when related equipment reads card information, and the metal visual card does not need to be in contact with the card, so long as the metal visual card is close to the card.
Of course, one metal sheet 101 may be used to make a plurality of metal shells 1 or metal printed sheets 2, so that a plurality of metal video cards may be made at a time. After the metal visible card is formed, the metal visible card is cut into single cards by using a laser cutting machine, and the edges of the cards are polished in order to enable the cards to have attractive and comfortable hand feeling.
The metal visual card provided by the invention can also be made into a contact card. After the metal visible card is molded, grooves 7 are milled on the card by using CNC (Computer numerical control) engraving equipment, 8 grooves 7 are milled in total and are arranged into circles, as shown in fig. 6; the lower part of the groove 7 is the position of the safety chip in the electronic module, the carrier tape is placed on the groove 7 (namely, the surface of the groove 7) and is subjected to hot-pressing encapsulation, so that the carrier tape is contacted with the safety chip, and the card achieves the contact function. The touch function refers to that when related equipment (such as POS (Point of sales) machine) reads card information, the card is required to be inserted into a card slot of the POS machine to be contacted with the POS machine, and the POS machine can only read information of the security chip through the carrier tape.
In summary, the invention provides a method for manufacturing a metal visual card, which fills the gap of the prior art for manufacturing the visual card by adopting a metal material. The metal visual card not only has the non-contact and contact functions of a common card, but also adds an OTP (One-Time Password) algorithm into the electronic module, so that OTP dynamic passwords can be realized.
