Face Pay runs a contactless fare system using VisionLabs face recognition; users upload a photo, a server extracts a 512-byte descriptor from ~40 facial features, and station servers receive updated descriptor lists every 15 minutes. Matching happens locally (one-to-many index) to avoid outages; liveness checks run in under 0.1s, detection is the heaviest step, matching takes hundredths of a second. Deployed across metro lines and MCC tests use 16 vCPUs/32GB nodes; about 200k users are active.
