StarSign Key Fob

Convenient and secure: the ultimate biometric device for individual authentication needs, anytime, anywhere



What is Key Fob?

StarSign Key Fob – the ultimate fingerprint device for quick, easy and secure online transactions.

G+D’s StarSign Key Fob is the first biometrics enabled FIDO security key in the market that combines FIDO with physical access control applications and payment applications in one device.

The Key Fob is a crypto hardware token in a stylish shape, convenient to carry and easy to use. The integrated fingerprint sensor on the top of the device can be used to quickly confirm transactions by pressing a finger on the sensor surface. Equipped with FIDO standards, the Key Fob authenticates the user and removes the reliance on passwords by using the built-in biometrics combined with a tamper-proof Secure Element and a multi-channel interface.

As a result, the user profits enormously from a very strong multi-factor authentication solution with highly improved security, usability and scalability, which is 100% compliant to standards like PSD2 and can be used on any platform at any time. More and more systems and services are enabled for multi-factor authentication with the open standard FIDO from the FIDO Alliance which allows use of the StarSign Key Fob at a large scale for fast and secure logins.

The StarSign Key Fob is part of our StarSign authentication portfolio and can be perfectly combined with our FIDO Server for a turn-key end-to-end solution. Thanks to the 100% FIDO compatibility, it can be individually combined with any other FIDO server in the market as well and can be used out-of-the-box in any customer environment.

Enterprises nowadays have the challenge to integrate a variety of different employee devices like desktop PCs, workstations, notebooks, mobile device securely into their network.

Existing solutions do not necessarily work on mobile devices and are not easy to integrate. Software-based authentication solutions are often regarded as not secure enough or do not satisfy the required security level in enterprises from a compliance perspective and are not easy to maintain in a heterogeneous IT environment.

The StarSign Key Fob is the game changer allowing all use cases to be integrated securely and seamlessly without increasing the costs. It will largely improve the efficiency of employees providing a great user experience and a fast and easy handling of the device.

Key Fob for the Financial Services Industry


StarSign Key Fob - for one touch secure contactless payment

Improving the overall user experience and removing friction is key for financial institutions deploying online and mobile applications. User experience has a direct impact on customer retention, ROI of online services, and operational costs. Banks are looking for solutions to simplify the process of in-store payments, to improve user experience and security at the same time. Dealing with PINs, as used today for credit cards and bank cards, is quite cumbersome and the trend to remove the PINs for lower amounts implies a high risk.

Banks are also looking for new concepts like a payment device that can be shared amongst family members safely, while using separated accounts on it. In parallel new regulations such as PSD2 require strong two-factor authentication for any kind of payment transaction on the internet. G+D’s StarSign Key Fob is the answer to all these requirements and uniquely performs all in-store and online payment transactions securely remaining compliant, in a seamless and convenient way.

As a mobile payment enabled device, it allows an active management of the payment credentials by the end-user itself and includes the creation, activation, deactivation and termination of virtual payment cards which are stored on the built-in Secure Element. The user verification is performed on the user’s personal key fob device itself and hence does not require any interactions with the payment terminal which potentially avoids contaminations.

As the key fob is easy-to-use and providing a seamless user experience it can also be the device of choice for elderly persons to perform their transactions safely.
