Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application can be used for various system applications related to the related business operation in the read-write operation process of the intelligent card, in particular to the operations of information read-write of the intelligent card, information check write-back of the intelligent card and the like. In practical application, the card writing method of the embodiment of the application can be particularly applied to scenes of using card reading equipment to pay fees for smart cards and the like. Smart cards may include, but are not limited to: water cards, electricity cards, gas cards, bus cards, and the like.
In the prior art, the card writing process for the smart card is generally to write 16-ary data directly into the specified data bits of the smart card. However, in the actual operation of the user, there are many uncontrollable factors, for example, there are various misoperation such as card loosening, poor chip identification, card pulling, etc., which cause the data to be incorrectly read and written, and finally, situations may occur that the actual service operation is terminated but the data is successfully written, or the data is not successfully written but the next service operation is actually performed. Under the conditions, due to the fact that the data is inconsistent, the subsequent related business data cannot be identified and used, business processing failure and economic loss are caused, the data is difficult to find at the later stage in the process, the system needs to manually check and erase the data and the like for recovery, and the card data is damaged.
In order to solve the above problems, embodiments of the present application provide a special card writing method in a series of card reading and writing processes, which accurately monitors whether card reading abnormality, card writing failure, card pulling action, and the like exist in the card writing process, and timely performs operations such as data checking, write back, erasing, and warning, thereby avoiding that, when a card is written, card writing data has deviation due to various reasons such as misoperation, which causes related service data to be unrecognizable and usable, affects subsequent service operations, improves the accuracy of system autonomous judgment to a greater extent, and reduces the burden of system manual checking and the risk of card data damage.
The card writing method according to the embodiment of the present application will be described in detail below.
Referring to fig. 1, a flowchart illustrating steps of a card writing method according to an embodiment of the present application is shown. The card writing method shown in fig. 1 can be applied to a card reading device or the like.
As shown in fig. 1, the card writing method may include the steps of:
In the embodiment of the application, the first data to be written into the smart card can be obtained according to the initial data in the smart card and the user input data.
In an alternative embodiment, first, initial data in the smart card (the initial data may refer to current data in the smart card that needs to be adjusted) may be read, user input data is obtained, and adjustment data for the initial data is determined according to the user input data; then, according to the initial data in the smart card and the determined adjustment data, first data to be written into the smart card can be obtained through calculation. As an example, the sum of the initial data and the determined adjustment data in the smart card may be used as the first data to be written to the smart card.
For example, in a situation of paying by an electric card, first, initial electric quantity data (initial data) in the electric card is read, payment amount (user input data) input by a user is acquired, and adjustment electric quantity data (adjustment data) for the initial electric quantity data is calculated according to the payment amount input by the user; and then, taking the sum of the initial electric quantity data in the electric card and the calculated adjustment electric quantity data as first data to be written into the intelligent card.
For another example, for a scene of bus card payment, first, reading initial amount data (initial data) in the bus card, acquiring a payment amount (user input data) input by a user, and using the payment amount input by the user as adjustment amount data (adjustment data) for the initial amount data; and then, taking the sum of the initial amount data in the bus card and the calculated adjustment amount data as first data to be written into the intelligent card.
It can be understood that, in an actual application, the first data to be written into the smart card may also be obtained in other manners, and the processing may be performed specifically according to an actual application scenario, and this embodiment is not discussed in detail herein.
For example, the first data to be written into the smart card may include, but is not limited to, business data and the like, for example, the above-mentioned electric quantity data and money amount data are all business data.
Illustratively, the first data to be written to the smart card may include, but is not limited to, business data, current date, and the like. By carrying the current date in the first data to be written into the smart card, the time of the occurrence of the abnormality can be known through the current date after the abnormality occurs in the card writing process, so that the abnormal situation can be known in more detail.
And 102, writing the first data into a preset check bit in the smart card.
In the embodiment of the application, a preset check bit is preset in the smart card, and the preset check bit is similar to a preset vacancy.
The smart card includes a data storage unit therein, which is where the smart card stores data, and the data storage unit may include a plurality of data bits (also referred to as address bits) for storing data. In the embodiment of the present application, one or more data bits that are arbitrarily applicable may be selected from the data storage unit as the preset check bit.
In the embodiment of the application, after the first data to be written into the smart card is obtained, the first data is not directly written into the target data bit in the smart card, but the first data is written into the preset check bit in the smart card.
It should be noted that, before writing the first data into the preset check bit in the smart card, if data already exists in the preset check bit (the data may be data written in the last card writing operation), the data in the preset check bit may be erased first, and then the first data is written into the preset check bit in the smart card.
In an alternative embodiment, based on the data security consideration, the first data to be written into the smart card may be encrypted, and then the encrypted first data is written into the preset check bit in the smart card. In implementation, any suitable encryption manner may be used to perform an encryption operation on the first data to be written into the smart card, for example, performing an exclusive or operation, a symmetric encryption, an asymmetric encryption, and the like on the first data to be written into the smart card, which is not limited in this embodiment of the present application.
In the embodiment of the present application, after the first data is written into the preset check bit in the smart card, the first data written into the preset check bit is used as the second data.
In order to ensure the accuracy of the second data written into the preset check bits in the smart card and prevent that the second data cannot be identified or is incomplete due to an abnormality of the smart card before the second data is written into the target data bits in the smart card, thereby causing a write failure when the second data is written into the target data bits, in this embodiment of the application, after the first data is written into the preset check bits in the smart card, the second data in the preset check bits may be checked to determine whether the second data in the preset check bits needs to be formally written into the target data bits in the smart card.
In an optional implementation manner, the checking the second data in the preset check bits may include: reading the second data from the preset check bits; comparing the second data with the first data; under the condition of consistent comparison, the verification is determined to be successful; and determining that the verification fails when the comparison is inconsistent.
In a possible scenario, if an error occurs in the written first data during the process of writing the first data to be written into the smart card into the preset check bit in the smart card, the second data read from the preset check bit may be inconsistent with the first data to be written into the smart card, and thus the verification will fail in this case.
In another possible scenario, the card reading device may monitor whether the smart card is abnormal in real time, in practical application, when the smart card is abnormal, a corresponding abnormal signal may be triggered, and after the card reading device monitors the abnormal signal, it may be determined that the smart card is abnormal. If the smart card is abnormal in the process of reading the second data from the preset check bit, the second data read from the preset check bit may be incomplete or cannot be identified, and the second data read from the preset check bit is inconsistent with the first data to be written into the smart card, so that the verification fails in such a case.
Exemplary situations where the smart card is abnormal may include, but are not limited to: smart card pull out, smart card loose, smart card chip identification error, etc.
And 104, writing the second data into a target data bit in the smart card after the verification is successful.
In the embodiment of the present application, after the second data in the preset check bits is successfully checked, it may be stated that no error occurs in the written first data in the process of writing the first data to be written into the smart card into the preset check bits in the smart card, and the smart card is not abnormal in the process of reading the second data from the preset check bits, so that it may be determined that data needs to be formally written back to the target data bits in the smart card, and therefore, the second data in the preset check bits may be written into the target data bits in the smart card.
After the second data in the preset check bits fails to be checked, it can be shown that an error occurs in the written first data in the process of writing the first data to be written into the smart card into the preset check bits in the smart card, or an abnormality occurs in the smart card in the process of reading the second data from the preset check bits, so that it can be determined that data does not need to be formally written back to the target data bits in the smart card, and therefore, the second data in the preset check bits is not written into the target data bits in the smart card.
Illustratively, the target data bit in the smart card may refer to the data bit in which the initial data in the smart card mentioned in step 101 above is located.
In practical applications, during the process of writing the second data in the preset check bits into the target data bits in the smart card, the second data may be used to replace the initial data in the target data bits. Therefore, the initial data in the target data bits may be erased, the second data may be read from the preset check bits, and the second data may be written into the target data bits in the smart card.
In the embodiment of the application, the first data to be written into the smart card is not directly written into the target data bit in the smart card, but the first data is written into the preset check bit by adding the preset check bit, the first data is checked after the first data is written into the smart card, so that whether the written data is accurate or not is determined, whether formal card writing operation needs to be performed or not is further determined according to the check result, and the data in the preset check bit is written back into the target data bit in the smart card after the check is successful, so that accidental data loss and damage can be effectively prevented, the error rate of card writing is reduced, the accuracy of autonomous determination of a system is improved, and the repeated operation of manual check is reduced.
Referring to fig. 2, a schematic diagram of a card writing process according to an embodiment of the present application is shown. The card writing process shown in fig. 2 can be applied to a card reading device or the like.
As shown in fig. 2, the card writing process may include the following steps:
In the embodiment of the application, the initial data (i.e. the current data to be adjusted) in the smart card is read first, and then the first data to be written into the smart card is obtained according to the read initial data and the user input data. For a specific process of acquiring the first data to be written into the smart card, reference may be made to the related description of step 101, and the embodiments of the present application are not discussed in detail herein.
And step 202, writing the card.
Specifically, the card writing step may include the following steps 2021 to 2023.
In the embodiment of the application, after the first data to be written into the smart card is obtained, the first data to be written into the smart card is written into the preset check bit in the smart card.
Taking the example that the first data to be written into the smart card includes the service data and the current date, the service data and the current date may be subjected to an exclusive or operation, and then the result obtained by the exclusive or operation is written into the preset check bit in the smart card. For a specific process of writing the first data to be written into the smart card into the preset check bits in the smart card, reference may be made to the related description of step 102, and the embodiments of the present application will not be discussed in detail herein.
In the embodiment of the present application, in the checking operation process, second data in the preset check bit is specifically checked, where the second data refers to first data written in the preset check bit. For the specific process of the verifying operation, reference may be made to the related description of the above-mentioned step 103 section, and the embodiments of the present application are not discussed in detail here.
In the embodiment of the application, after the verification operation is successful, the second data in the preset verification bit is written into the target data bit in the smart card. For a specific process of writing the second data in the preset check bits into the target data bits in the smart card, reference may be made to the related description of step 104, and the embodiments of the present application will not be discussed in detail herein.
After the verification operation fails, the second data in the preset verification bit is not written into the target data bit in the smart card, and the system can autonomously process subsequent services according to the verification failure condition.
And step 203, completing card writing, and executing subsequent service operation according to the successful card writing condition.
After the card writing is completed, the system can continue to perform subsequent business operations, such as business operations of the link on the smart card.
And step 204, the card writing is not finished, and the subsequent business operation is autonomously processed according to the card writing failure condition.
When the card writing is not finished, the system cannot continue to execute subsequent business operation, and alarm information can be triggered so as to remind related personnel of abnormity in the card writing process.
Referring to fig. 3, a schematic diagram of another card writing process of an embodiment of the present application is shown. The card writing process shown in fig. 3 can be applied to a card reading device or the like.
As shown in fig. 3, the card writing process may include the following steps:
And step 303, monitoring whether the smart card is abnormal or not. If yes, go to step 304; if not, go to step 305.
In the embodiment of the application, in the process of writing the first data into the preset check bit in the smart card, whether the smart card is abnormal or not can be monitored in real time. The specific process may refer to the related description of step 103, and the embodiments of the present application are not discussed in detail herein.
And step 304, stopping writing the first data into the preset check bit in the smart card.
In the process of writing the first data into the preset check bit in the smart card, if the smart card is monitored to be abnormal, the first data cannot be successfully written into the preset check bit in the smart card, and therefore, in this case, the first data is stopped being written into the preset check bit. And alarm information can be triggered so as to remind related personnel of abnormality in the process of writing the first data into the preset check bit in the intelligent card.
The second data refers to the first data written in the preset check bits.
And verifying the second data in the preset check bits by comparing whether the second data is consistent with the first data or not. If the comparison result is consistent, the verification is successful; and if the comparison result is inconsistent, indicating that the verification fails.
And step 306, marking the checking state of the preset checking bit as checking failure, and erasing the second data in the preset checking bit.
After the verification fails, the verification state of the preset verification bit is marked as verification failure, and the second data verification failure in the preset verification bit can be recorded for reference of related personnel during subsequent business operation; by erasing the second data in the preset check bit, abnormal data can be cleared in time, and the accuracy of the data in the preset check bit is ensured. And alarm information can be triggered so as to remind relevant personnel that the second data in the preset check bits fail to be checked.
And when the user reads the card again, whether the user has abnormal operation can be known by reading the check state of the preset check bit, and the time of the abnormal operation can be known by reading the date written in the intelligent card.
Step 307, marking the check state of the preset check bit as successful check.
After the verification is successful, the verification state of the preset verification bit is marked as verification success, and the success of the verification of the second data in the preset verification bit can be recorded for reference of related personnel in subsequent business operation.
In the embodiment of the application, in the process of writing the second data into the target data bit in the smart card, whether the second data is successfully written can be monitored in real time.
Illustratively, during the process of writing the second data into the target data bit in the smart card, whether the smart card is abnormal or not can be monitored in real time. If the smart card is monitored to be abnormal, the second data cannot be successfully written into the target data bit in the smart card, namely, the second data writing fails. If the smart card is monitored to be not abnormal, the second data can be successfully written into the target data bit in the smart card, namely the second data is successfully written.
The third data refers to the second data that has been written in the target data bits.
After the second data writing fails, the writing state of the target data bit is marked as writing failure, and the writing failure of the target data bit can be recorded for reference of related personnel during subsequent business operation; and abnormal data can be cleared in time through the third data in the target data bit, so that the accuracy of the data in the target data bit is ensured. And may trigger an alarm message to alert the associated personnel that the target data bit write failed.
In step 311, the write status of the target data bit is marked as write success.
After the second data is successfully written, the writing state of the target data bit is marked as writing success, and the writing success of the target data bit can be recorded for reference of related personnel in subsequent business operation.
Before the system executes the next service operation, the system may obtain the check state of the preset check bit and the write-in state of the target data bit, and determine whether to execute the next service operation according to the check state of the preset check bit and the write-in state of the target data bit. The accuracy of the processing can be further improved by judging the double states.
And under the condition that the verification state of the preset verification bit is verification success and the writing state of the target data bit is writing success, determining to execute the next business operation.
When the check state of the preset check bit is a check failure and/or the write state of the target data bit is a write failure, it may be determined that the next service operation is not to be performed temporarily.
In the embodiment of the application, on the one hand, in the process of writing data into the preset check bit, whether the smart card is abnormal or not is monitored, and if the card is pulled out, loosened and other abnormal conditions occur, the writing of data into the preset check bit is stopped, so that the card can be formally written after data incomplete or accidental full writing can be prevented. On the other hand, after data is written into the preset check bit, the preset check bit is newly added for monitoring to judge whether formal card writing operation is needed, the preset check bit is similar to the preset vacancy, the data is written into the preset vacancy, whether the service data is consistent with the preset check bit data or not is judged, the check bit state of the preset check bit is set to be failed or successful, and then data erasing or formal card writing operation is carried out, so that error data is effectively prevented from being left on the smart card, and the situations of direct card loading link, accidental data loss and damage are prevented. On the other hand, after the formal card writing is finished, whether the data exist is judged according to the checking state of the preset checking bit and the writing state of the target data bit, and the action can correctly judge whether the uplink data and the downlink data are consistent, so that more accurate reference is provided for the next business operation.
The embodiment of the application is simple to realize, changes little to the prior art, can reduce the uplink and downlink errors of card writing data, not only improves the accuracy of autonomous judgment of the system, reduces the burdensome operation of artificial checking, maintenance personnel and a service system, but also reduces the error rate of service processing caused by the system, reduces the card data damage rate, and can effectively reduce the time and economic loss of artificial checking caused by the system. In addition, the alarm processing efficiency is improved, the alarm processing time is shortened, and the actual incidence relation between alarms can be reflected more truly and accurately, so that the accuracy of the determined root alarm is improved.
