Frequently asked Questions

Q: Can you make our device/wearable able to handle payments?
A: Yes. The secure chip we use (NXP SmartMX2 P60) is ready for payments.

Q: How does the chip communicate?
A: For interactions with devices it’s via NFC (Near Field Communication) to load or un-load services it communicates using a smartphone.

Q: What about BLE (Bluetooth Low Energy)?
A: There is a well defined BLE protocol described on GitHub. If your device connects to the chip over BLE, new services will also be possible to load onto the chip over BLE.

Q: What is NFC (Near Field Communication) technology?
A: Evolved from radio frequency identification (RFID) tech, an NFC chip operates as part of a wireless link. Once it’s detected and activated by a reader, small amounts of data between the two devices can be transferred when held a few centimetres from each other.

Q: How can NFC be used?
A: NFC chips stocked inside credit cards for contactless payments are nothing new. But a more recent and admittedly more enticing use case for NFC is with your smartphone, which can digitize your entire wallet.

Q: How do I order chips and how do I know which one to use?
A: We base our solution on the SmartMX2 P60 chip from NXP, but please contact us and we will guide and assist you. The chip will have to be personalized in the factory according to specific procedures. We also have 12NC model numbers one can use when ordering chips from NXP.

Q: What services are on the chip?
A: It’s a growing ecosystem and services are added ongoing. You can find anything between carpool access, security such as two factor authentication.

Q: Are your chips secure?
A: Yes, they are very secure. Our chips are EMVCo approved and Common Criteria EAL 5+ certified.

Q: What chip do you use?
A: SmartMX2 p60 chip from NXP. It is a passive off the shelf product. If there is a need for using an active chip, our platform can be ported to other secure chips too.

Q: How can I test the Fidesmo platform?
A: Start by signing up to the developer portal on, here you will find available documentations and forum. To try the platform just order a card with Fidesmo from our shop.

Q: Can I put the chip anywhere?
A: In principal, yes. You might want to consider consumer behavior and for e.g. how the contactless point of sales are placed. Also the antenna needs to be taken into account, the take advantage of the NFC technology, antenna or a booster needs to be connected to the chip.

Q: How do I get in contact with you?
A: Please mail to and we will assist.

Featured case


An implantable NFC chip with Fidesmo for security, payment, and cryptography applications

Announced at CeBIT 2016 the VivoKey is an implantable chip developed by the American company Dangerous Things. Thanks to Fidesmo the implant will allow the user to install security services such as OTP, U2F, PKI and PGP. New services can be added to the implant after implantation which means once the chip is under the skin it can stay put. As new services are added to the Fidesmo platform they too can be added to the implant. Recent additions like Ledgers Bitcoin wallet are a testament to the power of the Fidesmo platform. The inability to physically access the chip combined with the fast pace of software development means that not being able to update the chip after implantation is unthinkable. The Fidesmo platform solves this in a beautiful and intuitive way ensuring users can utilize every aspect of their implant. The VivoKey will be available in an open beta in the fall of 2016.
