The present disclosure provides a system and method for establishing a communicationchannel between a card and a card processing unit 106. The card is operatively coupled to thecard processing unit 106 through a card machine 102. Authentication of the cardis based on acomparison of a first key code associated with the card and a dataset including pre-stored keycodes. When the card is authenticated,asecondkey code is generated by the card processingunit 106. The card processing unit 106 enablesthe second key code to replace the first keycode on the memory associated with the card through the card machine 102. The second keycode replaces the first key code in the dataset. The system 100 issues a warning signalrepresenting detection of card cloning based on a negative comparison of the key codeassociated with the card and the dataset.
