Direct answer
The short answer
A long-range UHF reader detects an approved vehicle credential, commonly mounted inside the windshield, as the vehicle approaches the controlled entrance. When the credential is valid, the gate-control system can authorize entry. Reader location, lane geometry, credential placement and gate timing all affect reliable operation.
