<p>The present invention is directed to a system that includes a transaction unit that includes a microchip having a computer readable medium configured to store a unit identifier (UI) and at least one one-time-password (OTP) therein. The UI and the at least one OTP comprising transaction authentication data. The transaction unit is configured to transmit the transaction authentication data in response to receiving a predetermined signal. A reader device is configured to transmit the predetermined signal to interrogate the transaction unit and read the transaction authentication data. The reader device is configured to generate at least one authentication indicia in response to receiving an authentication signal. A server is coupled to the reader device. The server includes a database having at least one server OTP related to at least one unit identifier stored therein, the at least one server OTP and the at least one unit identifier comprising transaction verification data. The server is configured to compare the transaction authentication data with the transaction verification data. The server also is configured to transmit the authentication signal to the reader device if the transaction authentication data matches the transaction verification data.</p> |
