What was delivered
- Singapore and Malaysia checkpoint QR codes in one place, matched to the combination of people travelling together that day.
- Capture the latest shared QR from the gantry display with the phone camera and save it for the next crossing.
- A full-screen QR view for the gantry, and a home screen that installs like a native app.
- Sign-in limited to approved Google accounts, plus single-use guest codes that expire within a day for occasional passengers.
- A user list the admin manages, and a serverless backend with storage for the QR images.
Why it matters
The border crossing is the stressful part of the day. With every code ready before the car reaches the gantry, travelling together becomes clearer, faster and easier.
