The ISO/IEC 19790 standard defines hardware security module (HSM) baselines for government approval, making it central to digital identity design. Until recently it cost over €200, a barrier for non-specialists. Since July, the 2025 edition is free, as is the companion ISO/IEC 24759:2025 for test labs.

For mobile documents (mdoc), open access has taken a different form: stable drafts are published in the ISOWG10 GitHub repositories.
