## What is BioSeal Reader?

BioSeal Reader reads and verifies Visible Digital Seals (VDS) and 2D-Doc codes. Scan the code on a document or product: the app checks its signature, issuer and revocation, then shows the certified data.

The app reads 2D codes (DataMatrix, QR Code and PDF417) compliant with ISO 22376, the Otentik trust network extensions and the BioSeal extensions. It also reads 2D-Doc, the previous generation of VDS. Any change to the data breaks the electronic signature: BioSeal Reader detects it, confirms the authenticity of the data and the legitimacy of the issuer, and shows the information in one of the languages defined by the use case.

Holder verification: when the seal carries a biometric reference, the app compares the holder's face or fingerprints with it, after the holder's consent. The comparison runs on the phone; no biometric data is sent. Reading seals is free; biometric verification requires an id3 licence.

## Version history (last 5 releases)

### 10.0.1 — 2026-10-20

BioSeal Reader 10.0.1:
- Compressed photos shown in the seal view.
- Signed links: a seal presented through a link is valid only for that link.
- Holder consent on a dedicated page, with "I agree" and "I refuse".
- Fingerprints: one recognised hand is enough.
- Information reserved for the authenticated holder stays hidden.
- Fingerprint fix on some phones (Galaxy A34); better display of Cyrillic and Central European languages.
- BioSeal 2.1 and Face 10.2 engines.

### 10.0.0 — 2026-10-14

Major release of BioSeal Reader:
- Reading seals is free; biometric verification requires a pro licence.
- New result page: content, seal and identity, with the detail of every check (signature, validity, trust chain, revocation).
- New My account, About and Settings pages; activation by account, key or file.
- 27 languages, selectable in Settings.
- Consent asked before every biometric verification; the seal can be viewed without biometrics.
- BioSeal 2.0 engine and many fixes.

### 9.8.4 — 2026-09-24

This release brings the following fixes:

• Licence activation failures now state their real cause — no licence left on the account, credentials refused, licence already installed on another device — instead of a single message that wrongly pointed at your credentials.
• Activation keys can now be typed in: the field no longer mangles them.
• The app restarts from its launch screen when the system has closed it in the background, instead of showing a home screen whose engines are not initialised.
• Face comparison concludes on the first suitable frame when liveness detection is off.

### 9.8.2 — 2026-09-17

This release corrects the store listing. The app itself is unchanged.

• The privacy policy link now points to a publicly accessible page.
• Listing text and website link corrected.
• A French listing is now available.

### 9.8.1 — 2026-09-12

This release fixes two crashes and corrects how a seal's expiry is reported.

• Fixed: scanning a short malformed code could terminate the app. This was reachable from the
  camera and from an imported image or PDF.
• Fixed: a crash while loading a seal's resources (manifest, trust lists, certificates).
• The expiry date shown is now the seal's own, never its signing certificate's. A seal that
  declares no validity period is now reported as not expiring.
