This DisplayCard from InCard Technologies generates a new password at the push of a button. The numerical one-time password is shown in a box on the card itself.
The button is on the back of the DisplayCard. The password could be used in combination with a PIN (personal identification number) to provide two-factor authentication–and help online shoppers avoid fraud, InCard says.
Pressing the button on the back of the DisplayCard clears the screen and creates a new password.
The one-time passwords generated by the DisplayCard are authenticated by a secure server to help ensure that the cardholder is the one making the transaction. Also, the physical card must be present to serve up the password.
The chip on the DisplayCard does the work of coming up with one-time passwords. The card here, aimed at the European market, also includes a chip for making micropayments and other purposes. InCard is working on adding another chip that can store data such as store loyalty card information.
