One time password security smart card with an LED display is developed by Bundesdruckerei GmbH by using the silicon and solution support from Security ID IC chip maker Infineon. The security processor IC chip in the card generates a one-time password for each transaction and displays this on the integrated LED display. Requesting the one-time password in addition to the static password boosts the security of authentication and payment applications and protects against attacks on e.g. company networks and against card manipulation, according to Infineon. This technology is going to be on display at CeBIT in Hanover from 5 to 9 March, 2013.
Infineon explains each time the card is used, a dynamic PIN supplement (one-time password) is requested. The dynamic PIN is automatically generated for each transaction by the security chip in the card and displayed on the integrated LED display. The chip uses the energy radiated from the card reader to power the security chip and generate the password as well as to power the display elements. The LED display itself is embedded into the card so that the digits light up on the card surface.
"With this new system-on-documents technology, we have lifted the security of log-in processes to a whole new level," Ulrich Hamann, CEO of Bundesdruckerei GmbH.
Along with EC cards or credit cards, this card can be used for applications such as logging into PC, logging into social networks on the net.
