Problems solved by technology

[0009] 1. When the CPU card creates a file, it must first declare the type of the file to be created and the size of the file to be created; and, after confirmation, the length of the file is fixed and cannot be changed, so that the previously applied space cannot be used again
[0010] 2. After the CPU card creates a file, it cannot be deleted
[0011] 3. There are only a few types of CPU card files, that is, the file types are fixed
[0012] 4. The CPU card must create and write files by sending messages to the smart card, and the number of byt

Embodiment Construction

[0061] The application (Application) mentioned in the present invention generally refers to the application protocol and related data between the smart card and the card reading device (Card Acceptance Device, CAD). A typical smart card device generally includes an 8 or 16-bit microprocessor running at 3.7MHz, with 1K of RAM and more than 16K of non-volatile memory (programmable read-only memory or flash memory). Smart cards can be classified as contact and non-contact. Contactable smart cards communicate and work through physical contact between the reader and the smart card's 8 contacts, while non-contact smart cards rely on radio frequency signals to communicate within a typical distance of less than 2 feet.

[0062] The application of the typical smart card described in the present invention is not isolated, but includes smart card, card reading device and back-end application program. Referring to FIG. 2 , a device block diagram of a smart card application.

Abstract

This invention provides one method to establish application to intelligent card composed of capacitor and subject memory data, which comprises the following steps: processing capacitor identifying according to order message data; if it passes, then establishing capacitor into capacitor entrance and analyzing subject label from order message to judge whether the current application entrance label is same; if yes, inserting the current analysis subject into current application entrance list for memory. This invention intelligent card can be suitable for each industries with one common flow.

Description

technical field [0001] The invention relates to the field of data storage and information processing, in particular to a smart card and a method for creating applications and inserting objects into the smart card. Background technique [0002] Because existing magnetic stripe cards have defects such as poor security, banks at home and abroad are gradually adopting smart cards (CPU cards) to replace magnetic stripe cards, and have issued a large number of smart cards individually or jointly with industry users. Generally speaking, a smart card is a plastic card containing an embedded integrated circuit (IC), which contains a tiny central processing unit (CPU), ROM, RAM and other peripheral circuits. The integrated circuit has capabilities similar to those of a computer. , for example: running programs, processing input and output data. When using the above-mentioned CPU card, it is necessary to provide power and other interface devices from the outside. [0003] In order to...
