Introduction:
The project sets sight on authenticating the conventional Debit or Credit card transaction system. In the prevailing system though the Credit and Debit card paves a convenient mode of transactions, it is subjected to more jeopardy. As technology extends its limit, the way of hacking and cracking also goes along the road. In out proposed system, in every transaction with the Credit or Debit card a handshaking signal is achieved with the cardholder. The handshaking method is achieved by transferring the transaction time and the purchase details to the mobile of the cardholder by means of a GSM modem. From the acknowledgement and authentication received from the cardholder’s mobile further transaction proceeds. The system used the MCU for the security issues between the Mobile and the Card. Reports can also be generated for every successful authentication.
The cardholder will be asked for a reply by the GSM modem message. The message from the cardholder is the major authentication command. The MCU decodes the message and decides the operation to be performed. The status of the system for each individual process will be displayed using LCD s.
