Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention provides a transaction data acquisition method, an NFC controller, an application processor and a terminal, aiming at the problem that the existing NFC terminal cannot conveniently acquire non-contact transaction data in real time.
Example one
As shown in fig. 1, the method for acquiring transaction data according to the first embodiment of the present invention is applied to a near field communication NFC controller, and includes:
it should be noted that, an encryption/decryption logic circuit is added to the SE, and mainly implemented as follows: and external malicious analysis attack is prevented, and data security is protected. The SE may be disposed in the SWP-SIM card, may be disposed in the electronic device separately, or may be disposed on some external memory card, such as an SD card. Because the prior art mainly adopts the SWP-SIM card to perform non-contact transaction, the SE is arranged on the SWP-SIM card as an example for explanation in the invention.
The SWP-SIM card is a new-specification SIM card used for realizing non-contact transaction of the terminal. In this step 11, communication interaction between the SE in the SWP-SIM card and the contactless card reader is directly monitored.
when transaction communication is carried out between the SE and the non-contact card reader, transaction data in the transaction communication process are directly acquired, and the transaction data cannot be stored in the SE.
And step 13, sending the transaction data to an application processor for caching.
The transaction data may be transaction data of a bank card application and a bus card application, and the transaction data is finally sent to an upper layer application for processing, and the upper layer application does not directly perform information interaction with the NFC controller, so that the NFC controller needs to send the acquired transaction data to an application processor, and it needs to be noted that the application processor is responsible for controlling the operation of the upper layer application.
It should be noted that, in order to ensure that the transaction data can be smoothly transmitted to the upper layer application in the subsequent communication, the transaction data generally needs to include identification information of the non-contact transaction application performing the non-contact transaction, so as to distinguish which non-contact transaction application the transaction data belongs to, thereby ensuring that the upper layer application can obtain corresponding transaction data according to the identification information of the non-contact transaction application.
Example two
As shown in fig. 2, a second embodiment of the present invention provides an NFC controller, including:
the monitoring module 110 is used for monitoring a non-contact transaction channel between the secure chip SE and the non-contact card reader;
an obtaining module 120, configured to obtain transaction data from the contactless transaction channel when there is transaction data communication between the SE and the contactless card reader;
a first sending module 130, configured to send the transaction data to the application processor for caching.
The SE may be disposed in the SWP-SIM card, may be independently disposed in the electronic device, and may also be disposed on some external memory cards.
Optionally, the transaction data comprises identification information of a contactless transaction application.
It should be noted that the embodiment of the NFC controller is an NFC controller corresponding to the embodiment of the transaction data obtaining method in one-to-one correspondence, and all implementation manners in the embodiment of the obtaining method are applicable to the embodiment of the NFC controller, and the same technical effect can also be achieved.
EXAMPLE III
As shown in fig. 3, the method for acquiring transaction data according to the third embodiment of the present invention is applied to an application processor, and includes:
it should be noted that the transaction data is monitored by the NFC controller from a contactless transaction channel between the SE and the contactless reader.
It should be noted that the application processor caches the transaction data, and when the upper-layer application needs to use the transaction data, the transaction data that needs to be used can be directly acquired from the cached data of the application processor.
In the embodiment, the transaction data is cached in the application processor, so that the transaction data can be conveniently acquired by upper-layer application, and the transaction data acquisition time delay is shortened.
In order to ensure that the transaction data can be smoothly transmitted to the upper layer application in subsequent communication, the transaction data generally needs to include identification information of the non-contact transaction application, so that the transaction data is ensured to correspond to the upper layer application.
Example four
As shown in fig. 4, the method for acquiring transaction data according to the fourth embodiment of the present invention includes:
it should be noted that the transaction data is monitored by the NFC controller from a contactless transaction channel between the SE and the contactless reader.
and step 23, sending the transaction data to the corresponding upper-layer application.
It should be noted that, in order to ensure that the contactless transaction is performed smoothly, the cached transaction data needs to be sent to the upper layer application for processing, and in general, the application processor does not actively send the transaction data to the upper layer application, and therefore, in this embodiment, as shown in fig. 5, the specific implementation of step 23 includes:
it should be noted that the registration information mainly includes identification information of an upper application and identification information of a non-contact transaction application, and only the upper application registered in the application processor has the right to acquire transaction data, that is, when the application processor finds that the upper application corresponding to the newly cached transaction data is registered thereon, the upper application is notified of the information of the transaction data.
It should be noted that when new transaction data is cached in the application processor, it is necessary to determine which upper-layer application the transaction data belongs to, and when a certain upper-layer application is obtained, it is necessary to inform the upper-layer application of performing processing on the transaction data, and at this time, the application processor sends the transaction data to the corresponding upper-layer application according to a transaction data acquisition request fed back by the upper-layer application.
In order to ensure smooth transmission of the transaction data, the method for acquiring transaction data of this embodiment further includes:
acquiring registration information of an upper application, wherein the registration information comprises identification information of the upper application and identification information of a non-contact transaction application;
and storing the registration information.
Optionally, the registration information may further include a password for the upper layer application to log in the application processor.
In this embodiment, the application processor sends the newly cached transaction data to the corresponding upper layer application, and only the upper layer application registered in the application processor can receive the processing request of the transaction data related thereto, and the transaction data is acquired according to the processing request.
EXAMPLE five
As shown in fig. 6, an application processor according to a fifth embodiment of the present invention includes:
a receiving module 210, configured to receive transaction data sent by an NFC controller;
wherein the transaction data is heard by the NFC controller from a contactless transaction channel between the SE and the contactless reader;

the judging unit is used for judging whether registration information of the first upper layer application corresponding to the transaction data exists in the application processor or not;
an update message sending unit, configured to send a transaction data update message to the first upper layer application if registration information of the first upper layer application exists;
a request information receiving unit, configured to receive transaction data request information fed back by the first upper layer application according to the transaction data update message;
and the transaction data sending unit is used for sending the transaction data to the first upper application according to the transaction data request information.
Optionally, the application processor further comprises:
the system comprises a registration information acquisition module, a transaction processing module and a transaction processing module, wherein the registration information acquisition module is used for acquiring registration information of upper-layer application, and the registration information comprises identification information of the upper-layer application and identification information of non-contact transaction application;
and the storage module is used for storing the registration information.
It should be noted that the embodiment of the application processor is an application processor corresponding to the embodiment of the method for acquiring transaction data one to one, and all implementation manners in the embodiment of the acquiring method are applicable to the embodiment of the application processor, and the same technical effect can be achieved.
EXAMPLE six

It should be noted that, in the terminal in this embodiment, when performing a non-contact transaction, by performing monitoring between the SE in the SWP-SIM card and the non-contact card reader, when there is a transaction, transaction data is directly obtained, and then the transaction data is cached in the application processor, and the upper layer application can conveniently obtain the transaction data in the application processor, thereby avoiding a problem that a user is inconvenient to use because the SE function in the SWP-SIM card is limited and the transaction data cannot be obtained or cannot be obtained in real time.
It should be noted that the terminal may be any electronic device such as a mobile phone with NFC communication capability.
In practical applications, the terminal of the present invention is embodied as follows (wherein the terminal implements contactless transaction through SWP-SIM card):
as shown in fig. 7, a data acquisition module is added in the NFC controller of the terminal, and is used to monitor transactions between the SWP-SIM card and a contactless card reader (e.g., a POS terminal) in real time, acquire contactless transaction data between the SWP-SIM card and the contactless card reader, and transmit the contactless transaction data to an application processor of the terminal if new contactless transaction data is acquired.
A data caching module is added in the application processor and used for caching non-contact transaction data generated in a recent period of time, and meanwhile, the application processor provides an access interface for an upper layer application to access the non-contact transaction data; establishing a registration mechanism for accessing the upper-layer application, wherein the upper-layer application must register in the data cache module if wanting to access the data in the data cache module, and register a corresponding application ID (the application ID includes an upper-layer application ID and an ID of a non-contact transaction application that can be processed by the upper-layer application, so that the data cache module can distinguish transaction data and determine which upper-layer application the transaction data belongs to).
And meanwhile, an IF5 interface is added for realizing the access of the data in the data cache module by the upper layer application, and when new non-contact transaction data are added in the data cache module of the application processor, the corresponding upper layer application can be informed to acquire the non-contact transaction data in the data cache module through the IF5 interface.
Meanwhile, an IF1 interface is expanded to realize that the data acquisition module sends the non-contact transaction data to the data cache module.
The IF2 interface between the SWP-SIM card and the NFC controller is kept unchanged, and the baseband chip and the SWP-SIM card continue to communicate through the original IF4 interface (note that, in the present invention, there is no communication interaction between the baseband chip and the SWP-SIM card).
As shown in fig. 8, the process of acquiring the non-contact transaction data through the terminal includes:
step 1, a user holds an NFC terminal to conduct card swiping transactions on a non-contact POS terminal, such as offline consumption, loading and the like;
step 2, a data acquisition module in the NFC controller monitors a non-contact channel between the SWP-SIM card and the POS terminal all the time, and acquires transaction information therein, such as transaction time, transaction type, transaction amount and the like;
step 3, the data acquisition module uploads the acquired transaction information to a data cache module of the application processor;
step 4, the data cache module judges whether data updating exists, if so, a notification of the data updating is sent to an upper operating system, and the operating system sends the notification of the data updating to a related upper application;
and 5, the upper layer application interacts with the data caching module through the operating system to acquire the latest transaction information.
In the invention, the upper application on the terminal can conveniently acquire all transaction data between the NFC terminal and the non-contact card reader in real time, so that the problem of inconvenient use of a user due to the fact that the transaction data cannot be acquired or cannot be acquired in real time due to the function limitation of the SWP-SIM card is solved, the application range of the terminal is expanded by the mode, and the user experience effect is improved.
