Answer
Credentials on the phone, edge readers with strong cryptography, a cloud-managed policy plane, and visitor flows built into the same model. The badge is no longer the centre of gravity.
Visual Explanation
How to picture it.
Stack: Phone credential → Reader → Controller → Policy plane → Audit.
Real-World Example
From the field.
A corporate HQ moved 4,200 employees from cards to phone credentials in six weeks. Lost-credential tickets dropped 92%.
Lessons Learned
What to take away.
- 1Phone is the new badge.
- 2Visitor flows belong in the same model.
- 3Audit is a feature, not an afterthought.
