Method of general interface compatible with card senders and user cards of various specifications

Abstract

The invention relates to a communication protocol for product service, which relates to the technical field of information, in particular to a communication protocol which is used for different types of card sending devices in a card sending process and is invented for a uniform communication interface protocol, namely a method of a general interface compatible with card senders and user cards of various specifications. The method comprises the following steps of: through a communication protocol which runs between a card sender and a card sending party, developing card sending equipment at a time so as to provide various better card sending methods for a demanding enterprise; and dissolving different commands by using the protocol according to the requirement on the technical application specification of a standard smart card and explaining different command functions which correspond to different command sets of the card sending machine in different command word ways. Relevant technical problems such as the realization of compatibility with the data format of a general card sending command of most conventional card senders, and the like. The method has the advantages of eliminating the dependence of the conventional card sending command on a command set of the card sender, bringing convenience to a card sending equipment party and a user party, solving the problem of one-time complete development of the card sending equipment, avoiding development for a second time and improving working efficiency.

Description

technical field [0001] The invention relates to a communication protocol serving products in the field of information technology, especially a communication protocol with a general interface invented for the purpose of unifying the communication interface protocol for different types of card issuing equipment in the process of issuing cards, and is mainly used for multi-purpose In the process of issuing smart cards, it is a common communication protocol that can be used for most card issuing devices and most IC card designs. Background technique [0002] With the development of IC card technology, more and more business fields and industries have begun to issue their own smart cards. The application of smart cards is becoming more and more extensive, and there are more and more card issuing equipment and application companies. For most small and medium-sized enterprises, the technical ability and use cost of designing and issuing cards by themselves are too high, so it is im...
