Camera-based AI that automatically reads vehicle license plates as trucks enter or exit the scale, eliminating manual data entry.
## What is LPR? **License Plate Recognition (LPR)** uses a fixed camera and a deep-learning model to read the alphanumeric characters on a vehicle's plate in real time. At a scrap yard, LPR cameras are mounted at the inbound scale and outbound exit. ## Why scrap operators care - **Speed:** Trucks weigh in without the operator typing a plate. - **Fraud prevention:** Pairs the plate with the seller record so the same vehicle can't be used for two different identities. - **Compliance:** Many states (CA, NY, OH, TX, GA) require plate capture on every nonferrous transaction. ## How accuracy is measured A production-grade LPR system runs at **95–99% accuracy** in good light, drops to 85–90% at night or in heavy rain. WeighPay's AI Vision stack uses dual-frame validation to push night accuracy back above 95%. ## How WeighPay handles LPR WeighPay AI Vision LPR cameras stream to the scale workstation, auto-populate the ticket, and flag mismatches between the plate and the seller's prior visits.
