Abstract

Disclosed are an EMV implementation method and device, the method comprising: clearing original tag data within tags, and reading specific values of all the tags; allocating dynamic memory for the plurality of tags; according to the tags and the specific values corresponding to the tags, establishing a tag index table; according to the tag index table, searching for a target tag corresponding to tag data to be written, and writing the tag data into the target tag to use the dynamic memory. Access and maintenance are simple, and the memory requirements are low.

Description

technical field [0001] The present invention relates to the field of EMV realization, in particular to an EMV realization method and device. Background technique [0002] EMV adopts TLV (TLV structure is a transmission structure, a buf, through T (tag) index, through L (len) to specify the subsequent length, through V (value) to save the specified length format to store data, such as card number, track data, Card validity period, certificate, etc. The EMV standard is jointly initiated by the three major international bank card organizations - Europay (European card, has been acquired by MasterCard), MasterCard (MasterCard) and Visa (Visa). The technical standard transferred to the smart IC card is the financial payment standard based on the IC card, which has become a recognized global unified standard. [0003] MPOS is a new type of payment product, which is connected with general smart mobile devices such as mobile phones and tablets, and transmits information through the...
