Card reading terminal for reading card and working method thereof

Abstract

A card reading terminal. The card reading terminal comprises a receiving module, a first determining module, a first judging module, a first acquiring module, a second determining module, a second acquiring module, a third acquiring module, a first obtaining module, a fourth acquiring module, a first decrypting module, a generating module, a second obtaining module, an updating module, a third obtaining module, a fourth obtaining module, a reading module, a second judging module, an identifying module, a fifth obtaining module, a third judging module, an executing module, a fifth acquiring module, a sixth acquiring module, an encrypting module, a second decrypting module, and a sending module. According to the present invention, communication data between the card reading terminal and a card is secured, and is thus difficult to be intercepted, leaked, or tampered with, such that security is greatly improved.
