  • System and method for redeeming an electronic promotion code at a point of sale
    Patent number: 9141968
    Abstract: An authentication device and a mobile device work together for redeeming an electronic promotion code at a point of sale. Upon receipt of an electronic promotion code, the authentication device encrypts the electronic promotion code and transmits the encrypted promotion code to the mobile device. In response, the mobile device decrypts the encrypted promotion code and determines whether the decrypted promotion code satisfies one or more predefined conditions. If so, the mobile device displays a message, indicating a successful redemption of the promotion code at the point of sale. In some implementations, the message includes a confirmation code, which is provided to the authentication device for generating a transaction log record. In some implementations, the mobile device also generates a separate transaction log record for the promotion code and transmits the transaction log record to a remote server for further processing.
