What is ANPR / LPR?
Camera-based reading of a vehicle's registration plate to control gates, charge tariffs, or trigger access — the no-token alternative to RFID for parking access.
Also known as
ANPR / LPR — explained.
ANPR (Automatic Number Plate Recognition) — known as LPR (License Plate Recognition) in the US — uses a camera plus OCR software to read a vehicle's registration plate as it approaches a gate. The plate becomes the access token: the system looks it up against a subscriber database to open the gate, calculate the tariff, or trigger an access event. The advantages over RFID: no physical token to issue or replace, lower per-user cost, and a frictionless visitor / one-off experience. The disadvantages: read reliability depends on camera quality, lighting, plate cleanliness, weather, and plate format compliance — typical reliable read rates are 95-99% on clean plates in good lighting, dropping sharply in fog, rain, or with dirty / damaged plates. Modern parking deployments often combine ANPR (for visitors and one-off transactions) with RFID (for high-throughput subscribers and high-security access where reliability matters). The same technology underpins toll roads, low-emission zones, and security perimeters.

Smart Parking
Smart ParkingA parking platform combining gate / barrier control, ticket or RFID access, payment, occupancy sensing, and a back-office for tariffs and reporting.
RFID (Radio Frequency Identification)
Smart ParkingA contactless ID technology — a small radio tag presented to a reader returns a unique code, used widely for parking, access control, and asset tracking.
Gate Barrier
Smart ParkingThe physical arm or boom that admits or refuses a vehicle at a parking entry / exit — controlled by the parking platform via RFID, ANPR, ticket, or mobile token.
Loop Detector
Smart ParkingA buried wire loop in the road surface that detects a vehicle's presence via inductance change — the most reliable vehicle-detection technology for gate barriers and counting.
Pay-on-Foot
Smart ParkingA parking payment model where the driver pays at a kiosk before returning to their vehicle — reducing exit-queue delays vs. paying at the exit barrier.
