The existing smart card usually includes a card base, a smart chip is disposed in the card base, and a preset program can be run in the smart chip and user data and the like can be recorded.
Referring to fig. 1, a conventional smart card has a card base 10, a smart chip 18 embedded in the card base 10, and a plurality of electrical contacts exposed on a surface of the smart card 18, wherein when the smart card is inserted into a card reading device, the electrical contacts contact and communicate with electrical contacts on the card reading device.
Referring to fig. 2, the card base 10 includes, in order from top to bottom, a first protective film layer 11, a first printing layer 12, a first adhesive layer 13, a substrate layer 14, a second adhesive layer 15, a second printing layer 16, and a second protective film layer 17. The first printing layer 12 and the second printing layer 16 may be printed with predetermined characters and patterns. The smart card shown in fig. 2 is a dual interface card, i.e. the smart card has functions of contact communication and non-contact communication, therefore, an antenna 19 is embedded in the substrate layer 14, the antenna 19 forms an induction coil, and the antenna 19 is electrically connected with the smart chip 18.
When the smart card approaches the contactless card reading device, the antenna of the contactless card reading device emits an induced magnetic field, the antenna 19 in the smart card induces the induced magnetic field to generate a current and supply power to the smart chip 18, and the contactless card reading device communicates with the smart chip 18 in a wireless communication manner to read data stored in the smart chip 18.
With the development of technology, the requirements of smart cards for their functions are increasing, and besides the basic data storage function of smart cards, smart cards are also expected to have functions that satisfy the needs of people in daily life, such as measuring the body temperature of the card holder. For example, in the new crown pneumonia epidemic situation of 2020, many public places require that the temperature of the person entering the place be measured, and the person is allowed to enter the place only if the temperature is within the normal range. And the smart card is as the articles for use that people carried with oneself usually and conveniently carried, if possess the function of body temperature measurement, will make things convenient for people in time to know the body temperature situation of self greatly, even when getting into public place, can let public place managers know card holder's body temperature through showing the smart card, reduce because of the problem that public place managers measured and lead to personnel to gather.
For example, chinese utility model patent with publication number CN207924716U discloses a transaction card capable of displaying different patterns by sensing temperature, which includes a sensing layer with a non-contact transaction unit or a contact transaction unit, when the environmental temperature changes, the transaction card generates different patterns, so as to achieve the effect of beauty. However, the transaction card has a very large temperature sensing change range, which is usually far beyond the human body temperature change range, and cannot accurately indicate the human body temperature, i.e. the transaction card does not have the function of measuring the body temperature. In addition, the transaction card not only has the current temperature condition, but also has inaccurate temperature detection if the temperature condition of the card holder is inferred only by the change of the pattern on the transaction card.
Disclosure of Invention
It is a first object of the present invention to provide a smart card capable of measuring body temperature indicative of the body temperature of a card holder.
The second purpose of the invention is to provide a method for manufacturing the smart card capable of measuring the temperature of the human body.
In order to realize the first purpose of the invention, the intelligent card capable of measuring the temperature of the human body comprises a card base, wherein a containing cavity is arranged in the card base, a temperature sensing assembly is arranged in the containing cavity, the temperature sensing assembly comprises at least one temperature-change ink packaging body, and temperature-change ink is packaged in the temperature-change ink packaging body; the temperature sensing assembly comprises a temperature sensing assembly, temperature change ink packaging bodies and a temperature sensing assembly, wherein the surface of the temperature sensing assembly is printed with temperature marks, the temperature marks are positioned above the temperature change ink packaging bodies, and a temperature mark matched with the temperature change ink packaging bodies is arranged above each temperature change ink packaging body; or each temperature-sensitive ink package is arranged in a numerical shape of temperature matching the temperature-sensitive ink package.
According to the scheme, the temperature sensing assembly is arranged in the smart card, each temperature-sensitive ink packaging body of the temperature sensing assembly corresponds to one temperature, and the corresponding temperature identification is printed on the temperature-sensitive ink packaging body, so that a user can visually check the corresponding temperature through the color-sensitive temperature-sensitive ink, and the current body temperature of a card holder is confirmed. Because the temperature sensing assembly corresponds to the range of the temperature of the human body, the temperature corresponding to each temperature change ink is a smaller interval range, and the temperature of the card holder can be accurately reflected.
Preferably, the temperature indication is a temperature scale and/or a temperature value. Since the temperature scale or the temperature value is very visually observed, the temperature scale or the temperature value is printed on the smart card, so that the user can check the body temperature of the cardholder in a short time.
Further, a transparent protective layer is arranged on the upper surface of the temperature-change ink packaging body. The protective layer is arranged to be transparent, so that the situation that a user observes the color change of the temperature change ink due to the fact that the temperature change ink is shielded by the protective layer is avoided. In addition, the protective layer is arranged, so that the temperature sensing assembly can be prevented from being damaged, and the service life of the intelligent card is prolonged.
Further, the temperature indication is printed on the protective layer. Directly print the temperature sign on the protective layer, can utilize the protective layer as the base member of printing on the one hand, simplify the technology that the smart card was made, on the other hand can not shelter from the temperature sign by transparent protection film, perhaps influence watching of temperature sign.
In a further aspect, the number of the temperature-sensitive ink packages is two or more, and the plurality of temperature-sensitive ink packages are arranged in parallel in the temperature-sensitive assembly.

Therefore, each temperature-sensitive ink packaging body can display three different colors, and the three states of being close to an accurate value, being larger than the accurate value and being smaller than the accurate value are indicated respectively, so that a user can clearly know the body temperature state of a card holder through temperature identification and the corresponding color of the temperature-sensitive ink packaging body, and the detection of the body temperature is more accurate.
In order to achieve the second object, the method for manufacturing the smart card provided by the invention comprises the steps of forming a groove in a card substrate, and placing a temperature sensing component in the groove; and pressing the temperature sensing assembly and the card base under the conditions of low temperature and low pressure.

One preferred scheme is that after the temperature sensing assembly is placed in the groove, a protective layer printed with temperature marks is placed on the surface of the temperature sensing assembly; the temperature sensing assembly and the card base are pressed under the conditions of low temperature and low pressure, and the method comprises the following steps: and pressing the protective layer, the temperature sensing assembly and the card base under the conditions of low temperature and low pressure.
Therefore, the protective layer is arranged on the surface of the temperature sensing assembly, so that the temperature sensing assembly can be protected, and the service life of the intelligent card is prolonged.
The further proposal is that before the protective layer, the temperature sensing assembly and the card base are pressed, the protective layer, the temperature sensing assembly and the card base are positioned by using a positioning piece.
Therefore, the protective layer, the temperature sensing assembly and the card base are positioned through the positioning assembly, and the condition that temperature indication is inaccurate due to displacement of the temperature marks printed on the protective layer is avoided.
In a further aspect, a press pad is disposed between the upper surface of the protective layer and the press device when the protective layer, the temperature sensing assembly, and the clip are pressed together.
Therefore, the pressing pad is arranged between the intelligent card and the steel plate of the pressing device, and the intelligent card can be prevented from being damaged by the steel plate of the pressing device.

the intelligent card capable of measuring the temperature of the human body can be a bank card, a bus card, a membership card and the like, can be a contact intelligent card, a non-contact intelligent card or a double-interface card, and the double interface is an intelligent card with two functions of contact payment and non-contact payment.
Referring to fig. 3, the smart card of the present embodiment has a card base 20, a smart chip 25 is embedded in the card base 20, and preferably, a surface of the smart chip 25 is provided with a plurality of electrical contacts, which are exposed on the surface of the smart card, and when the smart card is inserted into a card reading device, the electrical contacts contact and communicate with the electrical contacts on the card reading device.
In addition, a window 26 is provided on the card base 10, and a temperature sensing element 21 is provided in the window 26, see fig. 4, and the temperature sensing element 21 is embedded in the card base 20. In this embodiment, the card base 20 is provided with an accommodating cavity 24 therein, and the temperature sensing element 21 is provided in the accommodating cavity 24. The identification cover 22 is provided above the temperature sensing element 21, and preferably, the identification cover 22 is a transparent filler, and the identification cover 22 covers only the upper surface of the temperature sensing element 21. Preferably, the identification cover 22 is made of a material with a high thermal conductivity so as to rapidly transmit the heat of the human body to the temperature sensing member 21 through the identification cover 22.
In addition, a transparent protection layer 23 is further disposed on the surface of the card base 20, the protection layer 23 is a transparent protection film, such as a PE film, and the protection layer 23 covers not only the upper surface of the identification protection layer 22, but also most of the area of the card base 20, such as the area except for the smart chip 25, covered with the protection layer 23.
Referring to fig. 5, a plurality of temperature-sensitive ink packages are disposed in the temperature sensing assembly 21, including temperature- sensitive ink packages 31, 32, 33, and 34, and referring to fig. 3, each of the temperature- sensitive ink packages 31, 32, 33, and 34 is substantially in the shape of a strip, and the temperature- sensitive ink packages 31, 32, 33, and 34 are disposed in parallel. Further, each of the temperature- sensitive ink packages 31, 32, 33, 34 is packaged with one ink, each of which shows a specific color at a specific temperature for indicating the current temperature. For example, the temperature change ink in the temperature change ink package 31 corresponds to 36 ℃, the temperature change ink in the temperature change ink package 32 corresponds to 37 ℃, the temperature change ink in the temperature change ink package 33 corresponds to 38 ℃, and the temperature change ink in the temperature change ink package 34 corresponds to 39 ℃. Certainly, in practical application, more temperature-sensitive ink packages may be disposed in the temperature sensing assembly 21, the temperature-sensitive ink in each temperature-sensitive ink package corresponds to a specific temperature, the specific temperature may be from 34 ℃ to 40 ℃, and the temperature-sensitive ink in each temperature-sensitive ink package corresponds to one of the integral temperature values, that is, 34 ℃, 35 ℃, 36 ℃, 37 ℃, 38 ℃, 39 ℃ and 40 ℃.
In order to make the user know the current temperature more intuitively, a temperature sensing element display area 27 is arranged in the window 26, a plurality of temperature- sensitive ink packages 31, 32, 33, 34 of the temperature sensing element 21 are arranged in the temperature sensing element display area 27, and the upper surface of each temperature- sensitive ink package 31, 32, 33, 34 is provided with a corresponding temperature mark. The temperature is marked in this embodiment as a scale 29 of temperature and a numerical value 28 of the corresponding temperature is printed near each scale. Of course, the value 28 of the temperature can also be directly printed on the upper surface of the corresponding temperature-sensitive ink package.
As can be seen from fig. 3, the scale 29 for temperature is a scale line printed on the upper surface of the display area 27 of the temperature sensing assembly. In this embodiment, a scale 29 of the temperature and a numerical value 28 of the temperature are printed on the protective layer 23. Since the protective layer 23 is transparent, the user can visually see the scale lines and the color of the temperature-sensitive ink packages below the scale lines.
Optionally, the temperature identifier is not printed on the protection layer 23, but is directly printed on the identification protection layer 22, so that the transparent protection layer 23 does not shield the temperature identifier on the identification protection layer 22, and a user can visually observe the color of each temperature-sensitive ink package and the corresponding temperature identifier.
In this embodiment, the temperature corresponding to the temperature-change ink packaged by each temperature-change ink package is different, and the temperature-change ink packaged by each temperature-change ink package has a corresponding upper temperature threshold and a corresponding lower temperature threshold, and when the temperature is higher than the upper temperature threshold or equal to the lower temperature threshold, the temperature-change ink package is transparent. And when the temperature is between the upper temperature threshold and the first temperature value, the temperature change ink packaging body displays a first color, when the temperature is between the first temperature value and the second temperature value, the temperature change ink packaging body displays a second color, and when the temperature is between the second temperature value and the lower temperature threshold, the temperature change ink packaging body displays a third color.
Specifically, the temperature-sensitive ink in the temperature-sensitive ink package 31 corresponds to 36 ℃, that is, the accurate temperature value corresponding to the temperature-sensitive ink in the temperature-sensitive ink package 31 is 36 ℃, the upper temperature threshold and the lower temperature threshold of the temperature-sensitive ink in the temperature-sensitive ink package 31 are respectively 35.5 ℃ and 36.5 ℃, and when the temperature of the temperature sensing assembly 21 is lower than 35.5 ℃ or higher than 36.5 ℃, the temperature-sensitive ink package 31 is displayed to be transparent, that is, the color is not changed. The temperature-change ink package 31 is colored brown when the temperature sensing element 21 is at a temperature between 35.5 ℃ and 35.9 ℃, the temperature-change ink package 31 is colored green when the temperature sensing element 21 is at a temperature between 35.9 ℃ and 36.1 ℃, and the temperature-change ink package 31 is colored blue when the temperature sensing element 21 is at a temperature between 36.1 ℃ and 36.5 ℃. By analogy, other temperature-sensitive ink packages also have similar color changes.
In this way, the user can visually determine the body temperature of the cardholder through the color change of the temperature-change ink packaging body on the temperature sensing assembly 21 and the corresponding temperature identification. For example, if the color of the temperature-sensitive ink packs 32 on the temperature sensing unit 21 changes and the color of the other temperature-sensitive ink packs is transparent, it indicates that the temperature of the card holder is about 37 ℃. At this time, the temperature of the cardholder can be determined by observing the color of the temperature change ink pack 32, for example, if the color of the temperature change ink pack 32 is green, the exact temperature value indicating that the temperature of the cardholder is 37 ℃ is very small, if the color of the temperature change ink pack 32 is brown, the temperature of the cardholder is 0.5 ℃ below 37 ℃, i.e., between 36.5 ℃ and 37 ℃, and if the color of the temperature change ink pack 32 is blue, the temperature of the cardholder is 0.5 ℃ above 37 ℃, i.e., between 37 ℃ and 37.5 ℃.
Similarly, when the color of the temperature-sensitive ink package 33 on the temperature sensing element 21 changes and the color of the other temperature-sensitive ink packages is transparent, it indicates that the body temperature of the card holder is about 38 ℃. At this time, the temperature of the cardholder can be determined by observing the color of the temperature change ink pack 33, for example, if the color of the temperature change ink pack 33 is green, the exact temperature value indicating that the temperature of the cardholder is 38 ℃ is very small, if the color of the temperature change ink pack 33 is brown, the temperature of the cardholder is 0.5 ℃ below 38 ℃, that is, between 37.5 ℃ and 38 ℃, and if the color of the temperature change ink pack 33 is blue, the temperature of the cardholder is 0.5 ℃ above 38 ℃, that is, between 38 ℃ and 38.5 ℃.
Because the temperature sensing ink contains the crystallized crystal particles, when the temperature of the temperature sensing assembly 21 changes, and the structure of the crystal particles in the temperature sensing ink slightly changes, the refraction and reflection conditions of the temperature sensing ink to light beams with different wavelengths also change correspondingly, and the wavelengths of the refracted and reflected light waves are related to the temperature, so that each temperature sensing ink packaging body in the temperature sensing assembly 21 presents different colors when the temperature changes. For example, the patent application with publication number CN110216929A discloses a thermochromic film structure capable of displaying characters and patterns according to temperature and being reused, wherein a thermochromic ink is disposed in the thermochromic film structure and displays different characters and patterns at different temperatures. Optionally, the temperature-sensitive ink of this embodiment is liquid crystal ink, and the liquid crystal ink is also commonly applied to an existing temperature-sensitive liquid crystal color-sensitive thermometer, and is also used as a temperature indicator on a product such as an annealing sticker.
Because the temperature change ink measurement error of each temperature change ink packaging body of the temperature sensing assembly 21 is about 0.5 ℃, and the color change of each temperature change ink packaging body is very obvious, a user can very intuitively know the body temperature state of a card holder. Moreover, the color of the temperature-sensitive ink changes rapidly, and usually, the cardholder only needs to hold the window 26 with fingers for about 10 seconds, so that the color of the temperature-sensitive ink package of the temperature sensing assembly 21 changes, and the temperature of the human body is measured. Moreover, when the temperature of the temperature sensing element 21 is lowered, the color of the temperature-sensitive ink package is restored to be transparent, and when the temperature of the temperature sensing element 21 is raised again, the color of the temperature-sensitive ink package is changed again, that is, the temperature sensing element 21 can be reused, and the use is very convenient. In addition, because the temperature change ink is adopted as the temperature indication in the embodiment, the problem that the traditional thermometer is easy to cause glass breakage is avoided.
In the above embodiment, the temperature-change ink packages are arranged in a cube and a plurality of temperature-change ink packages are arranged in parallel, so that in practical application, the temperature-change ink packages can be arranged in a digital shape corresponding to the temperature, for example, the temperature-change ink packages corresponding to 38 ℃ are arranged in a digital "38" shape in the temperature sensing assembly 21, and the user can also know the body temperature of the card holder very intuitively.
It should be noted that, if the smart card is a dual interface card, the card base 20 may further be provided with a coil, and the coil is electrically connected to the smart chip 25. If the smart card is provided with only a contactless payment function, the smart chip does not need to be exposed on the surface of the smart card, and can be embedded in the card base, and the coil is provided in the card base.
The embodiment of the manufacturing method of the smart card capable of measuring the temperature of the human body comprises the following steps:
when a smart card capable of measuring the temperature of the human body is manufactured, the card base 20 is first manufactured, and a groove is formed in the card base 20, for example, a groove is milled in the card base 20, and the size of the groove is determined according to the shape and size of the temperature sensing element 21.
Then, the temperature sensing member 21 is placed in the recess, and the identification protective layer 22 is placed on the temperature sensing member 21, and the protective layer 23 printed with the temperature indication is placed on the card base 20, for example, to form the structure shown in fig. 4. Preferably, the protective layer 23, the identification protective layer 22, the temperature sensing element 21 and the card base 20 are positioned by using a positioning member, for example, a heating nail head is used to position the protective layer 23, the identification protective layer 22, the temperature sensing element 21 and the card base 20, so as to avoid the situation that the position of the temperature mark is not matched with that of the temperature-sensitive ink package body due to the position deviation among the protective layer 23, the identification protective layer 22, the temperature sensing element 21 and the card base 20 in the pressing process.
Subsequently, the heat-sealing is carried out under low temperature and low pressure conditions, for example, at a pressing temperature of 80 ℃ to 120 ℃, at a pressing pressure of 5 Pa to 12 Pa, and for a pressing time of 15 minutes to 25 minutes. Preferably, a lamination pad of PE film is laminated between the surface of the protective layer 23 and the steel plate of the lamination device to prevent the card base from being damaged by lamination, and finally the card body with the temperature sensing assembly is extruded. Generally, the above process is performed on a large substrate, and since the area of the substrate is large, the card body is required to be punched according to the size of the smart card product after lamination, so as to meet the size requirement.
After the steps, the card body does not encapsulate the smart chip, so that the groove needs to be milled and the smart chip needs to be loaded according to the traditional process, and the smart card is formed.
The intelligent card can be applied to various fields, can be used as a bank card, can also be used as an access control card, a membership card and the like, for example, before a cardholder enters a specific place, the color of a corresponding temperature-variable ink packaging body in the temperature sensing assembly can be changed by holding the intelligent card for a period of time, a user can visually observe the color condition of the temperature-variable ink packaging body to quickly judge the temperature of the cardholder, the cardholder is prevented from queuing to measure the temperature, and the efficiency of entering places by the cardholder is improved. In addition, due to the private property of the smart card, the card holder can measure the body temperature without contacting any public object, and the risk of contacting the public object and viruses when the body temperature is measured is reduced.
Finally, it should be emphasized that the present invention is not limited to the above-described embodiments, such as the change of the type of the temperature-changing ink used, or the change of the setting position of the temperature indicator, and such changes should be included in the protection scope of the claims of the present invention.
