In order to better understand the technical solutions, the technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings and the specific embodiments.
Referring to fig. 1, an embodiment of the present invention provides a method for activating an IC card, which may be applied to an initial IC card, that is, steps of the method for activating an IC card in an embodiment of the present invention may be executed by the initial IC card. In the embodiment of the present invention, the activation refers to activating an initial IC card, and the initial IC card may be understood as a white card, that is, the initial IC card does not have any function, while the activated initial IC card may have functions of one or more functional IC cards.
Referring to fig. 2, fig. 2 is a schematic structural diagram of an initial IC card in an embodiment of the present invention, where the initial IC card includes an MCU21, a memory 22 and a signal contact group 23, and both the memory 22 and the signal contact group 23 are connected to an MCU21, where the connection may refer to an electrical connection, through which the MCU21 may respectively perform data communication with the memory 22 and the signal storage contact group 23, for example, may perform data communication according to an iso7816-3 protocol.
The MCU21 can be a module or a unit with a data processing function, and in a specific implementation process, the MCU21 can be embodied in a chip, that is, the MCU21 can be a chip with a data processing capability. The MCU21 may have a plurality of pins through which electrical connections are made to the memory 22 and the signal contact set 2.
the Memory 22 is a storage medium having a data storage capability, such as a RAM (random access Memory), a ROM (Read-Only Memory), a Flash Memory, and so on, and in the implementation process, different media of the Memory can be selected according to actual needs, the Memory 22 may include a plurality of storage areas, and the data reading performance of each storage area may be the same or different, for example, the Memory 22 includes 3 storage areas, one of the storage areas supports reading and writing of data at the same time, the other storage area supports reading of data but does not support writing of data, and the remaining storage area does not support reading of data but supports writing of data, in addition, a corresponding encryption level may be set for each storage area, for example, a first encryption level may be set for a part of the storage areas, the remaining storage area is set to a second encryption level, wherein the degree of encryption of the first encryption level may be higher or lower than the second encryption level.
The memory 22 may include one or more code areas, for example, as illustrated in fig. 2 by taking the case that the memory 22 includes 4 code areas (i.e., code area 1-code area 4), each code area stores a corresponding code, and the initial IC card can be provided with a function included in a corresponding one of the functional IC cards by running the code included in any one of the code areas, that is, the initial IC card can be activated by running the code included in the code area. For example, the initial IC card may be made to function as a gas card by running the codes in the code area 1, the initial IC card may be made to function as an electric card by running the codes in the code area 3, and so on, and the gas card and the electric card mentioned here may be understood as the functional IC cards in the embodiments of the present invention.
In a specific implementation process, the multiple code regions included in the memory 22 may belong to the same storage region, or may belong to different storage regions, which is not limited in this embodiment of the present invention.
the signal contact group 23 may include at least two signal contacts, for example, at least a voltage signal contact and a data signal contact, and may further include a ground signal contact, a clock signal contact, and a reset signal contact, etc., and fig. 2 illustrates an example of 5 signal contacts including the contacts 1 to 5. In a specific implementation, the signal contact group 23 may be designed integrally, that is, a plurality of signal contacts included in the signal contact group 23 may be disposed as close as possible, and each signal contact included in the signal contact group 23 is capable of transmitting an electrical signal, and may be disposed in the form of a gold finger, for example.
in addition, the initial IC card may further include a housing, such as a rectangular frame shown in fig. 2 and enclosing the MCU21, the memory 22 and the signal contact set 23, in a specific implementation process, the MCU21 and the memory 22 are integrated in the housing, the MCU21 and the memory 22 can be protected by the housing, and the signal contact set 23 can be embedded in the housing, that is, all the signal contacts included in the signal contact set 23 can be directly seen from the appearance, so that when the IC card is inserted into the card reading device, contact data communication can be performed between the signal contacts in the signal contact set 23 and the card reading device, such as an electric card or a gas card used in daily life, and the electric card or the gas card is inserted into an electric meter or a gas meter, and so on.
with continued reference to fig. 1, the flow of the method of activating an IC card in the embodiment of the present invention is described as follows.
Step 11: determining that connection is established between the initial IC card and the activation control device; the initial IC card comprises M code areas, and the initial IC card can be provided with functions corresponding to the function IC card by running codes contained in any one of the M code areas.
Where M is a positive integer, such as 1, 2, 4, etc., as illustrated in fig. 2, i.e. 4 code regions.
In a specific implementation process, the initial IC card may be understood as a white card, and after the activation of the initial IC card is controlled by the activation control device, the initial IC card may be enabled to present a function of a corresponding functional IC card, that is, activation from the white card to the functional IC card is realized.
Since the initial IC card cannot be automatically activated, the activation is controlled by the requirement of the user, when the initial IC card needs to be activated, the user may use the activation control device to control the initial IC card to perform the activation operation, for example, the user may operate the activation control device to send an activation control instruction to the initial IC card, and the initial IC card may perform the activation operation after receiving the activation control instruction.
The activation control device may be, for example, a PC (personal computer), a notebook computer, a mobile phone, or a dedicated activation device, as long as an activation control instruction can be sent to the initial IC card through the activation control device, and the specific type of the activation control device is not limited in the embodiment of the present invention.
in the implementation, for example, the following manner may be adopted to determine whether the initial IC card establishes the connection with the activation control device, and it should be understood that the embodiments of the present invention include, but are not limited to, the following manner.
the first mode is as follows:
When the initial IC card needs to be activated, the initial IC card may be inserted into the activation control device, that is, the initial IC card may perform contact communication with the activation control device through the signal contact group 23 in the initial IC card, at this time, the first voltage signal contact in the signal contact group 23 may detect the first contact voltage that is inserted, and if the first contact voltage belongs to a first predetermined voltage range, it may be determined that a connection is established between the initial IC card and the activation control device.
That is, whether the connection with the activation control device is established or not can be determined by the voltage magnitude detected by the voltage signal contact, so that the connection accuracy of the activation control device can be ensured, for this reason, a first predetermined voltage range can be set in advance for the activation control device, for example, the first predetermined voltage range is set to [2.2V, 2.6V ], only if the detected voltage belongs to the voltage range, the initial IC card is considered to be successfully established with the activation control device, and then the instruction sent by the activation control device is executed, otherwise, the connection can be considered to be invalid, for example, the user inserts the initial IC card into other devices due to misoperation, and the other devices are not devices for which the user controls the initial IC card to be activated.
The second mode is as follows:
when the initial IC card needs to be activated, the initial IC card may be inserted into the activation control device, that is, the initial IC card performs contact communication with the activation control device through the signal contact group 23 in the initial IC card, at this time, the data signal contact in the signal contact group 23 may receive device identification information sent by a connected device, the initial IC card determines whether a device identification corresponding to the device identification information belongs to a predetermined device identification set, and if it is determined that the device identification belongs to the predetermined device identification set, it indicates that the device connected at this time is a device for controlling the initial IC card to be activated, that is, it is determined that the connection with the activation control device is successfully established.
Alternatively, when the initial IC card is inserted into the activation control device, a verification code may be sent to the initial IC card, and the initial IC card may obtain the verification code through the data signal contact, and further determine whether the verification code is legal to determine whether the device connected at this time is a legal activation control device.
The third mode is as follows:
The initial IC card can be also provided with an interface, the interface can be connected with a matched interface on the activation control equipment, the activation control equipment can send verification information to the initial IC card through the matched interface, and if the initial IC card determines that the verification information is legal, the connected equipment is determined to be legal activation control equipment.
Step 12: acquiring an activation control instruction sent by activation control equipment; wherein the activation control instruction is used for instructing the initial IC card to activate the functions of the N-function IC card.
Wherein the functions of the N-function IC card are those of the N-function IC card corresponding to N of the M code zones, for example, the activation control instruction is for instructing the initial IC card to activate the functions of the function IC card corresponding to the code zone 1 and the code zone 3, respectively, as shown in fig. 2, and the function IC card corresponding to the code zone 1 is a gas card and the function IC card corresponding to the code zone 3 is an electric card.
And N is an integer less than or equal to M, that is, the activation control command may instruct the initial IC card to activate one or a plurality of functions of the functional IC card at the same time. When N is 1, this indicates that the user wishes to activate the initial IC card as a functional IC card (e.g., a gas card), and after activation, the initial IC card has the function of a gas card and can be used as a gas card. When N is larger than 1, the user wants to activate the initial IC card into a plurality of functional IC cards, such as the functions of a gas card and an electric card, and the purpose of one card for multiple purposes can be achieved. In the specific implementation process, the user can select to activate one or more functions according to respective actual requirements, and the personalized requirements of the user can be met as much as possible due to the fact that one or more functions can be selected to be activated.
In a possible embodiment, an operation interface may be displayed on the activation control device, a list of various functional IC cards included in the initial IC card may be displayed in the operation interface, and the user only needs to select an option of a functional IC card that the user desires to activate, and after the user performs a selection operation, for example, after a click operation, the activation control device may determine a function that the user desires to activate according to operation information of the user, and further generate a corresponding activation control instruction and send the activation control instruction to the initial IC card.
in another possible implementation manner, the user can also directly input a control code to the activation control device, and the activation control device can determine the type of the functional IC card which the user wishes to activate by running the control code input by the user, and further generate a corresponding activation control instruction and send the activation control instruction to the initial IC card.
Step 13: according to the activation control instruction, the codes included in the N code areas corresponding to the N functional IC cards in the M code areas are respectively operated, so that the initial IC card activates the functions of the N functional IC cards.
because the activation control instruction is used for instructing the initial IC card to activate the N functions corresponding to the N code areas, after the activation control instruction sent by the activation control device is obtained, the initial IC card determines the N code areas corresponding to the N functions from the M code areas, and then respectively operates the codes included in the N code areas, so as to achieve the purpose of activating the functions of the IC card with the N functions.
Step 14: the initial IC card which activates the functions of the N-function IC cards is taken as the activated function IC card.
After the codes included in the N code areas are run, the initial IC card is activated as an IC card having the aforementioned N functions.
for example, if the gas card of the user is lost, in order to replenish the gas card, the initial IC card may be activated as the gas card in the manner described in the foregoing steps 11 to 14, so as to achieve the purpose of replenishing the card quickly.
Moreover, for the functional IC card close to production halt or due to production halt in the market at present, the card supplementing mode in the embodiment of the invention is very convenient to adopt. For example, for a specific type of gas card, a manufacturer may stop production for some reason and do not produce any more, but if the gas card is to be replaced by another type of gas card, the corresponding gas meter may not be used, so the gas meter needs to be replaced, however, the price of the gas meter is generally high, and the cost is too high if the gas card is replaced in a large scale, which causes resource waste.
in addition, after the initial IC card is activated as the function of the aforementioned N-function IC card, the data stored in the code region other than the N code regions corresponding to the N-function IC card may be deleted, for example, after the initial IC card is converted into a gas card by running the codes included in the code region 1 as shown in fig. 2, the codes included in the code regions 2 to 4 may be deleted, because the codes in the code regions 2 to 4 become invalid data after the initial IC card is activated, and the deletion thereof may make more storage space for the IC card, so that the use data of the user may be stored as much as possible later in the use process.
In practice, a new functional IC card may be provided for the user in the above manner, or a lost or damaged functional IC card may be provided for the user, and when the new functional IC card is provided, after the initial IC card is activated, the first historical usage data sent by the activation control device may be received, where the first historical usage data is usage data corresponding to a first user identifier, and the first user identifier is information capable of identifying the user identity, such as a user name, a user identification number, or a card number to be provided, and the like, and the first historical usage data is historical usage data used by the functional IC card to be provided for the user (for example, referred to as a first functional IC card) before, and further, the first historical usage data is stored in a first storage area in the initial IC card, and the first storage area is a storage area allocated to the first functional IC card in the initial IC card for storing the usage data of the first functional IC card, for example, all usage data associated with the first type of functional IC card may be stored in the first storage area during subsequent use.
If the user is a card supplement, the use data of the user is generally stored in the lost or damaged card of the user, so that the normal use of the user is not influenced after the card is supplemented in the above manner, for example, if the user is a supplemented electric card, the user just supplements 30-yuan electric charge before the card is lost, and if the data in the lost electric card is updated to the newly supplemented electric card in the above manner, the user can directly insert the newly supplemented electric card into the electric meter for recharging, that is, the previously supplemented 30-yuan electric charge is input into the electric meter, so that the electricity is really purchased, and the normal use of the user after the card is supplemented is ensured.
In the specific implementation process, for the power grid system or the gas system, the usage data of all the users can be stored in a server in a centralized manner, the activation control device can obtain historical usage data corresponding to each user identification from the server,
one possible situation is that only the function of one functional IC card, for example, only the function of a gas card, is activated when the original IC card is activated. Under the condition, when the activated gas card is inserted into the gas meter, data interaction can be carried out between the data signal contact in the gas card and the corresponding contact in the slot in the gas meter so as to realize data communication between the gas card and the gas meter.
in this case, how to ensure that the user does not confuse the functions when using the functions of the gas card and the electric card, respectively, but uses them normally:
After the initial IC card is activated, that is, after the activated functional IC card is obtained, the user may use the IC card for normal use, for example, the user may insert the IC card into a corresponding metering device, for example, the metering device corresponding to the gas card is a gas meter, and the metering device corresponding to the electric card is an electric meter, at this time, the activated functional IC card may detect a second contact voltage, to which the IC card is connected, through a second voltage signal contact in the signal contact group 23, and then determine, according to a corresponding relationship between the voltage range and the type of the functional IC card, that the type of the IC card corresponding to a second predetermined voltage range to which the second contact voltage belongs is the second type of functional IC card, and communicate with the contacted metering device by using a function corresponding to the second type of functional IC card.
That is, different operating voltage ranges may be set in advance for IC cards of different functions. For example, the operating voltage ranges set for the gas meter and the electric card are [3.0V, 3.8V ] and [4.5V, 5.2V ], respectively, then in the using process, when a user wishes to use the function corresponding to the gas card, the IC card is directly inserted into the gas meter, and the operating voltage (i.e. the aforementioned second contact voltage) can be obtained from the gas meter through the contact with the gas meter, for example, the detected second contact voltage is 3.3V, since 3.3V belongs to the voltage range of [3.0V, 3.8V ], the activated IC card can know the function of the gas card that the user wishes to use at this time according to 3.3V, and then the function corresponding to the gas card can communicate with the contacted device (i.e. the gas meter), and the function of the electric card cannot be mistakenly communicated with the gas meter, so that the effective use of the IC card can be ensured, and the occurrence of false response can be avoided.
