Age Verification
The problem
Door staff and checkouts rely on eyeballing a card and doing birthday maths — slow at peak, easy to fool with a borrowed ID, and every check exposes a whole identity when only one fact matters.
How it's solved
Verify an mDL's over-18 flag with a TENSAI reader — cryptographically signed, with no date of birth revealed. For physical cards, AI OCR reads the document in seconds; add face match to confirm the ID belongs to the person holding it.
What changes
- Checks that keep queues moving at peak
- Only the over-18 fact is shared — nothing else stored
- Borrowed and forged IDs are far harder to pass
