Photo Verification Glossary
Plain-English definitions of the concepts behind photo verification — from policy-as-code and end-of-ride checks to AIAG damage grades and proof of delivery.
AIAG Damage Grade
An AIAG damage grade is a standardized classification of vehicle damage based on the Automotive Industry Action Group's grading framework, used so that the same dent or scratch is graded the same way regardless of who inspects it or when.
Read definitionBefore/After Delta
A before/after delta is the comparison of an asset's condition at two points in time — typically handoff and return — that isolates what changed, separating new damage from pre-existing wear.
Read definitionEnd-of-Ride Verification
End-of-ride verification is the check a shared micromobility operator runs when a rider ends a trip: the rider photographs the parked vehicle, and the photo is verified against the city's parking rules before the ride can close.
Read definitionK1–K5 Damage Scale
The K1–K5 scale is a severity grading scale for vehicle damage, running from K1 (minor, often cosmetic wear) through K5 (severe damage typically requiring part replacement), used to classify defects consistently during inspections.
Read definitionOn-Device Inference
On-device inference is running an AI model directly on the user's device — the phone — rather than sending the image to a server for analysis. It enables fast, offline-capable verification with better data privacy.
Read definitionPhoto Verification API
A photo verification API is a service that accepts an image plus a policy and returns a structured verdict — typically pass/fail with the reasons and a category — confirming that the photo shows a real-world condition or that it meets a defined rule.
Read definitionPolicy-as-Code
Policy-as-code is the practice of expressing a verification rule set — the categories, the per-criterion checks, the severity, and what gates a pass or fail — as plain, editable, version-controlled configuration rather than hard-coded or opaque model behavior.
Read definitionProof of Delivery (POD)
Proof of delivery (POD) is documented evidence that a shipment reached its intended recipient or destination. Modern POD is increasingly a verified, timestamped photo of the placed package rather than just a signature or a status flag.
Read definitionSelf-Inspection Link
A self-inspection link is a one-time link sent to a customer that opens a guided photo-capture flow on their own phone — no app install — so they can document a vehicle or asset's condition themselves, creating an acknowledged, timestamped record.
