Method, system and apparatus for read-write operation of smart card

Abstract

The invention provides a method, a system and a device for processing reading-writing to an intelligent card which belong to the electronic technique field. The method, the system and the device are used for increasing reading-writing speed to a contact type intelligent card using ISO7816-3 agreement by an intelligent card reading-writing device. An embodiment of the invention includes steps as follows: the intelligent card reading-writing device confirms clock frequency supported by the intelligent card; the intelligent card reading-writing device selects one time frequency from the confirmed clock frequency, the selected clock frequency is more than present clock frequency of the intelligent card; the intelligent card reading-writing device uses the selected clock frequency for processing reset operation to the intelligent card, present clock frequency of the intelligent card is the selected clock frequency after the reset operation successful; the intelligent card reading-writing device processes reading and writing operation to the intelligent card. The method using the embodiment provided by the invention can increase reading-writing operation efficiency and user's experience.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method, system and device for reading and writing operations on smart cards. Background technique [0002] With the development of smart card technology, the application environment of smart cards is becoming more and more extensive. Due to the wide range of application environments of contact smart cards, the requirements for storage capacity and read / write speed of contact smart cards are also getting higher and higher. [0003] According to the ISO7816-3 standard, the smart card reading and writing device and the contact smart card are operated through the I / O interface. At present, the capacity of the contact smart card adopting the ISO7816-3 protocol is usually 8K, 32K or 64K. With the development of technology, contact smart cards with a capacity of more than 1M have appeared. [0004] However, the ISO7816-3 protocol is formulated with reference to contact smart car...

AI Technical Summary

Problems solved by technology

[0007] To sum up, the current smart card reading and writing device reads and writes the contact smart card using the ISO7816-3 protocol at a relatively slow speed, and it takes a long time to read and write.
