The system includes a third party server and a plurality of preregistered UEs. Each UE is configured to: receive a visual identifier associated with a magnetic card at the POS and transmit to the server a unique identifier of the POS/card and the unique identifier of the customer. The server is configured to: obtain financial details regarding the primary transaction generated by the POS, receive the unique identifier of the POS and the unique identifier of the customer from the UE, approve the primary transaction if financial settlement means associated with the customer are sufficient, and establish a secondary financial transaction between the customer and the third party, for settling the debt of the customer to the third party.
