Embodiment 1

[0053] Such as figure 1 As shown, the transaction data acquisition method in Embodiment 1 of the present invention is applied to a short-range wireless communication NFC controller, including:

[0054] Step 11, monitoring the contactless transaction channel between the security chip SE and the contactless card reader;

[0055] It should be noted that the encryption / decryption logic circuit is added to the SE, which is mainly implemented to prevent external malicious analysis attacks and protect data security. The SE can be set in the SWP-SIM card, can also be set independently in the electronic device, and can also be set in some external memory cards, such as SD cards. Because the SWP-SIM card is mainly used for contactless transactions in the prior art, therefore, in the present invention, SE is set on the SWP-SIM card as an example for illustration.

[0056] SWP-SIM card is a new type of SIM card, which is used to realize the contactless transaction of the terminal. Beca...

Embodiment 2

[0063] Such as figure 2 As shown, Embodiment 2 of the present invention provides an NFC controller, including:

[0064] The monitoring module 110 is used to monitor the contactless transaction channel between the security chip SE and the contactless card reader;

[0065] An acquisition module 120, configured to acquire transaction data from the contactless transaction channel when there is transaction data communication between the SE and the contactless card reader;

[0066] The first sending module 130 is configured to send the transaction data to the application processor for buffering.

[0067] Wherein, the SE can be set in the SWP-SIM card, can also be set independently in the electronic device, and can also be set on some external memory cards.

[0068] Optionally, the transaction data includes identification information of the contactless transaction application.

[0069] It should be noted that this NFC controller embodiment is an NFC controller corresponding to the ...

Embodiment 3

[0071] Such as image 3 As shown, the transaction data acquisition method in Embodiment 3 of the present invention is applied to an application processor, including:

[0072] Step 21, receiving the transaction data sent by the NFC controller;

[0073] It should be noted that the transaction data is monitored by the NFC controller from the contactless transaction channel between the SE and the contactless card reader.

[0074] Step 22, cache the transaction data.

[0075] 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 required transaction data can be directly obtained from the buffer data of the application processor.

[0076] In this embodiment, the transaction data is cached in the application processor, which facilitates the acquisition of transaction data by upper-layer applications and shortens the time delay for obtaining transaction data.

[0077] And in order t...

Abstract

The invention provides a transaction data acquisition method, an NFC controller, an application processor and a terminal. The transaction data acquisition method is applied to the NFC controller and comprises the steps that a non-contact transaction channel between a secure element (SE) and a non-contact card reader is monitored; when transaction data communication is generated between the SE and the non-contact card reader, transaction data is acquired from the non-contact transaction channel; the transaction data is sent to the application processor to be cached. According to the scheme, by means of monitoring between the SE and the non-contact card reader, the transaction data is directly acquired when a transaction is conducted and then cashed in the application processor, an upper application can conveniently acquire the transaction data from the application processor, the problem that use of a user is inconvenient due to the fact that the transaction data cannot be acquired or acquired in real time because of function limiting of the SE is avoided, and in this way, the application range of the non-contact transaction is widened.

Description

technical field [0001] The invention relates to the fields of terminals and e-commerce, in particular to a method for acquiring transaction data, an NFC controller, an application processor and a terminal. Background technique [0002] Near Field Communication (NFC) on-site payment will soon become the mainstream payment technology for on-site payment. However, at present, NFC non-contact information acquisition requires NFC terminals to access the SIM card. If the SIM card application does not provide transaction cache, then The NFC terminal will not be able to obtain; even if the SIM card application provides the corresponding cache, but because the information is scattered in each card application, it is difficult for the terminal to obtain it, and the upper layer application needs to obtain data one by one for each card application, which cannot achieve real-time acquisition. As a result, it is impossible to process corresponding big data; there may also be a problem tha...
