German companies Infineon Technologies AG and Bundesdruckerei GmbH have teamed up to develop a security smart card with an LED display that features a one-time password (OTP).
The technology in the card’s chip can generate a dynamic OTP, which it then displays on the LED screen. The system also has a static password, and together the two increase the security of authentication and payment applications.
The card reader generates the energy needed to power the chip, generate the OTP and power the display elements. The dynamic OTP is only generated on the card itself and cannot be read from the card’s display by other software, such as malware.
The polycarbonate card can be used for a variety of log-in situations, including PC network access and Internet social networks. It may be used with conventional reading devices or an NFC-enabled phone that can read the card.
The two companies have been partners since 2011, with Bundesdruckerei providing the cards and Infineon creating the chips and chip-to-card integration.
