Smart card manufacturer Giesecke & Devrient (G&D) has expanded its product portfolio by adding two new display card models to make online banking and online payments even more secure.

According to the company, presented in a compact credit card format, these products offer the ability to dynamically generate one-time passwords for online applications at the touch of a button, with the passwords appearing on a flexible display embedded within the card.

G&D said that by deploying its new display cards, financial institutions can provide their customers with additional security solutions for online banking and online payments by introducing the concept of dynamically generated one-time passwords (OTPs), which users enter in addition to their usual login name and password.

Access is not granted until the OTP has been successfully verified. The additional authentication provided by a one-time password ensures that the user is in possession of the card in question.

In addition to a basic card model, which only provides the OTP authentication function, G&D also offers a display card model which incorporates additional features and payment functions.

The company claims that this advanced model is capable of completely replacing existing electronic payment solutions such as traditional debit and credit cards. Users will benefit from the ability to use just one card to go shopping in the high street, purchase items online, and carry out secure online banking.

G&D head of the Payment division Axel Deininger said that security issues are increasingly coming to the fore in online banking. The company’s new card solutions are designed for consumers who are looking for enhanced security in an easy-to-use format.

"Banks and credit institutions benefit from a high degree of flexibility and an additional authentication system that is easy to integrate. G&D’s new display cards fulfill all the market requirements, offering a solution that can be introduced both rapidly and cost-effectively," Deininger said.

The new cards correspond to the ID1 format used by virtually all standard payment cards. Even though the card body is only around 0.8 millimeters thick, it comfortably integrates all the additional components.
