SafeHandover makes school pickups safe, fast, and fully verified — so no child leaves without parent knowledge and digital proof. 3-LAYER PICKUP VERIFICATION Teachers verify every guardian with three independent methods: • AI Face Recognition — enroll once in 60 seconds, verify instantly at the gate • Rotating Pickup Codes — a unique code auto-regenerates every 30 seconds and cannot be reused or guessed • QR Code Scan — one-tap scan from the teacher's camera Every pickup is recorded with a photo, timestamp, and the verification method used. "ON MY WAY" LIVE LOCATION Tap "I'm On My Way" and the school sees your live GPS, ETA, and distance. Your child is prepared before you arrive — reducing pickup wait by up to 40%. Runs in the background and stops automatically after pickup.
