Here you will find replies to some of the most common questions we get regarding the OFFPAD.

What does an OFFPAD do?

The OFFPAD is a hardware security key which replaces your passwords. It is more secure, quicker and convenient than what you do today. Simply activate the card with your fingerprint and it will do the rest to get you logged on to your services and applications.

What makes the OFFPAD safe?

The card has been designed following a Trusted Execution Environment (TEE) which makes all communication encrypted and secured. Additionally, the card is off most of the time (except during the authentication for a 3s period) which drastically limits the attack surface (potential the hacker has to interact with the card).

Where are my biometrics stored?

Your fingerprint biometrics are not stored like a picture in our card. An algorithm transforms your fingerprint biometric into a unique number which is encrypted and stored in a Secure Element. Your fingerprint is never shared outside the card. During the matching, the algorithm compares the given result of the authentication with the stored number. If there is a match the authentication is approved.

Why is it called OFFPAD?

OFFPAD stands for OFFline Personal Authentication Device, meaning that the device is mostly offline until it is used to authenticate towards a system/application.

How long does the battery last?

The battery lasts approximately 3 weeks. This will depend on individual usage.

How do you charge the battery?

The battery is charged wirelessly with a Qi charger. Same as for mobile phones, watches and other equipment supporting standard wireless charging.

Why do you have a screen?

The screen can be used for several things. The main usage is to receive visual confirmation from the service you are authenticating towards. The screen can also be personalized with your name, company name or other name of interest.

Can you use the OFFPAD as a physical access card as well?

This is under development and will be available soon.

What services support FIDO2?

FIDO2 (Fast Identity Online) is a common standard which has native support in all major operating systems like MS Windows, Apple OSX, Android and iOS all major web browsers like Firefox, Chrome, Edge, Mozilla, Safari etc. Most Identity Access Management (IAM) systems support FIDO2 out of the box. More details can be found at:

How do you enroll a fingerprint?

The first time you switch on the card, the display will show messages asking you to present your fingerprint to be registered (5 times for each). Once done, other fingerprints could be registered (if necessary) following the same steps.

How many fingerprints can you enroll?

You can register up to 3 different fingerprints on the card. Thanks to the Device Management App, you can add or delete registered fingerprints if needed.

What is the False Acceptance Rate (FAR) of your fingerprint sensor?

The FAR for the biometric sensor we are using is 1/20.000

What is the False Rejection Rate (FRR) of your fingerprint sensor?

The FRR is 3%

Why do I need separate hardware when a mobile phone can already do biometric authentication?

A mobile phone is designed to be online 24/7. It is also full of applications and all sorts of helpful and not so helpful tools from developers all over the world. Mobiles have and will be breached in many ways. The OFFPAD is offline until needed and is only used to authenticate you as a user. This makes it much better to withstand attacks.

Why does it look like a credit card?

At PONE Biometrics we think that a credit card form factor is the best compromise between convenience (easy to handle and manipulate) and security. Furthermore, this form factor is well known by all generations and is linked to security and easy to use.

Does it come in any other shapes?

PONE Biometrics is already preparing for the future by leveraging the best technologies to strengthen the product security and usability. Having another form factor is however not in our product roadmap as of today.

How can it communicate with the service it authenticates towards?

The OFFPAD has inbuilt support for both NFC and BLE and will use this to communicate with the device you are using to reach your required service/application.

Do you need to install anything on the devices you are connecting to?


What is the expected lifetime of an OFFPAD?

With standard usage (based on the respect of the standard precautions) the card is expected to have a lifetime of at least 3 years. At that time PONE Biometrics will supply you with a new OFFPAD.

What happens if someone steals my OFFPAD?

The card cannot be used because only your fingerprint can activate the card.

What happens if I break my OFFPAD?

PONE Biometrics wants to make daily user life easier. You will receive a new one according to your contract agreement and assurance policies.

How much does an OFFPAD cost?

PONE Biometrics want it to be easy and affordable to become more secure. We are therefore offering a rental price for each OFFPAD. Users who prefer to buy the OFFPAD can of course also do this. Please contact us for detailed pricing information.

Do we need to set up a big IT project to start using the OFFPAD?

Of course not. Our first idea is to make the authentication accessible to everyone. Thanks to contactless technologies like Bluetooth Low Energy (BLE) and Near Field Communication (NFC) the card can easily connect to any device. The card is FIDO2 compliant and will be seen as a trustable hardware when you’ll access FIDO2 compliant digital platforms such as Gmail, Facebook, Salesforce, SAP, Amazon, Windows Hello etc.

Where is the OFFPAD produced?

The OFFPAD is developed and produced here in Scandinavia. This lets us have complete control of all aspects of the product and therefore limit the possibilities for bad actors in the value chain.

What type of certification does the card support?

The card is certified FIDO2 level1 and CE to comply with EU regulation. Further certifications like FIPS 140-3 and Common Criteria are planned for soon.
