Digital Product Passport

The European battery passport is upcoming to enforce several laws for which the SandGrain solution could be a perfect fit: such as circularity, whilst offering the possibility of full life-cycle control including repair and refurbishment.

By 1st February 2027, all EV and industrial batteries on the EU market will require a unique battery passport. Information on the battery is to be retrieved using a unique identifier, and must include performance classification for carbon impact, electrochemical performance, and durability requirements.

The integrated, hard-coded SandGrain solution is ideally suited to enable the development and use of information systems that involves secure authentication. With a secured battery module authentication, advanced systems to manage the battery identities throughout their lifecycles can be created. This forms the necessary foundation for a secured circular economy for EV batteries.



Safe and secure – no matter what application

We provide a universal authentication platform for any connective device.

Today, cyber-attacks are a real concern. We believe in restoring trust and piece of mind in an ever-changing and expanding Internet-of-Things.

We have created a unique solution that can be applied universally to any connective device within the Internet-of-Things. It combines the best of both worlds: a secure cloud platform linked to a token physically attached to the device.


The secure cloud platform providing state-of-the-art cyber security and required software services.

  • Generates, assigns, and issues unique identities for hardware tokens
  • Validates authentication requests from tokens in de field.
  • State-of-the Art cyber-security
  • Infinitely scalable

Physically Unique ID

An immutable, hardwired, token that cannot be hacked.

  • A small IC that can be attached on the end-node of any IoT device
  • Immutable and extremely robust
  • Unique codes that are hard-coded on the IC using patented SandGrain technology
  • Communicates with CyberRock for authentication.
