Quick answer
Short answer
If your passport chip stops working, you will be routed to manual inspection. Some automated systems and airline check-in processes will not accept the document, which can mean long delays or denied boarding.
The practical consequences
Expect longer lines, secondary screening, and inconsistent treatment across countries. What one border waves through, another refuses.
The safe move
Replace it before you fly. If your trip is close, treat it as an urgent case rather than a routine renewal.
