Problems solved by technology

In the traditional implementation method, the composite application data is first moved to the memory, and then written to the file through atomic operations. These time-consuming data movement operations bring great difficulties to meet the transaction time requirements

Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0029] figure 1 It is a flowchart of a method for processing extended application data in an embodiment of the present invention, such as figure 1 As shown, the method of the present embodiment includes:

[0030] Step 11. After receiving the UPDATE CAPP DATA CACHE command, write the extended application data into the atomic write buffer;

[0031] Step 12: Submit the extended application data stored in the atomic write buffer after receiving the transaction completion instruction.

[0032] QPBOC extended applications and EDEP-type industry extended applications are to meet ...

Abstract

The invention provides a card, a device and a method for processing extensive application data. The method includes: after an order of updating extensive application data cache is received, writing extensive application data into an atomic write buffer zone of the card; after a transaction accomplishment instruction is received, submitting extensive application data stored in the atomic write buffer zone. By the card, the device and the method for processing extensive application data, RAM (random access memory) on the card can be saved while transaction time is shortened, and an atomic write function can be optimized.

Description

technical field [0001] The invention relates to the technical field of electronic commerce, in particular to a method and device for processing extended application data, and a card. Background technique [0002] QPBOC extended application and EDEP (electronic passbook electronic wallet) industry extended application add UPDATE CAPP (extended application) DATA CACHE command in the transaction of standard application, and the application imported by UPDATE CAPP DATA CACHE (update extended application data cache) command The data is stored in RAM (Random Access Memory, volatile access device), and the submission of the last instruction of the transaction is submitted together with other transaction data for atomic writing, which leads to two main problems: [0003] On the one hand, it is generally required in applications to support multiple UPDATE CAPP DATA CACHE commands in one transaction, and to allocate a relatively large space in the RAM of the card (such as the chip on ...
