G&D Launches Volume Production of its New Display Cards

Giesecke & Devrient (G&D) is introducing the world's first display card capable of being manufactured on a high-volume industrial scale. The six-digit display is incorporated in the card during the normal hot-lamination process, thereby augmenting its resistance to mechanical wear. G&D's GDC4000 display card can be used to display one-time passwords (OTPs) for secure authentication during access to IT networks, or transaction numbers (TANs) for online banking.

G&D has chosen Aveso, a specialist in flexible displays, to supply the display technology. Aveso will provide the display that will then be embedded together with various electronic components, a battery and a button in different layers of the card using a hot-lamination process. The finished card corresponds to the standard ISO ID1 format and is not thicker than usual types of credit card.

The use of a dynamically generated one-time password in conjunction with static customer data such as account number, user password and personal identification number (PIN) significantly enhances the security of online authentication. The display card makes it possible to add a supplementary, bi-directional identity check that protects users and providers of online banking services against the theft and fraudulent misuse of passwords and TANs. This additional verification works as follows: When the bank's background system receives the one-time password generated by the card, it responds by transmitting a second one-time password that appears on the customer's computer screen. When the customer now presses the button on the card, the password it displays must match that shown on the computer screen. This provides secure confirmation that the password was indeed sent by the bank.

The newly introduced GDC4000 version of the display card provides display functions only. A second, multifunctional version will be made available at a later date. It will contain an additional embedded chip enabling this version of the display card to be used for EMV (Europay-MasterCard-Visa), PKI (public key infrastructure) and customer loyalty applications. Both versions can be supplied with embossed lettering.

G&D will be exhibiting the GDC4000 display card at the CARTES & IDentification 2008 exhibition and congress in Paris from November 4-6, 2008 (Booth 4 L 001, Hall 4).
