How to take a photo with date, time and location
- Tap Start camera and allow the camera and location when your browser asks.
- Wait for the location line to show its ± m accuracy. Outdoors, GPS is usually more accurate.
- Type a note if you need one, like a shop name or job. Switch on Add map for a small map on the photo.
- Tap Take photo. The date, time, time zone, GPS coordinates and note are stamped onto the photo.
- Tap Save photo to keep it on your phone, or Share to send it straight to WhatsApp.
Handy for proof-of-work photos: cleaning jobs, deliveries, site checks, shelf displays in shops, or damage reports.
What a browser camera can't prove
- The time comes from the phone's clock. If someone changes the clock, the timestamp changes too.
- The location comes from the phone. A fake-location app can give wrong coordinates, and the browser can't tell.
- A saved photo can be edited afterwards, like any other photo.
For a team's work records, you need a system that keeps its own records. Here is the one we use.
The complete proof-of-work system we use
Our merchandisers visit shops every day. Every visit is recorded in the web app I built, Rapi. This is what it looks like, with sample data.
Aina, 15 Nov 2026
Start 09:05Finish 16:40
- Sample Mart A38 minBefore · Storeroom · After
- Sample Mart B52 minBefore · Storeroom · After
- Sample Mart C41 minBefore · Storeroom · After
- Sample Mart D: 6 min at the outlet (under 10 min)
- Sample Mart E: POF ticked without an order
- Finished 13:20 (before 14:00)
- Sample Mart F: out of stock
What our system does today
- Photos come from the in-app camera only; there is no gallery picker.
- Every stamp shows Malaysian time, GPS ± m, "(location N min old)" when it applies, the outlet and the staff name.
- A Google Maps link is saved with each photo.
- If the in-app camera fails, a fallback photo is stamped only with a fresh GPS fix, and marked as a fallback.
- Times more than 10 minutes in the future or more than 30 days old are ignored.
- A day card per merchandiser (start, finish, minutes per outlet, Before / Storeroom / After photos) and a month view.
- Red flags: under 10 minutes at an outlet, POF ticked without an order, finished before 14:00, outlet out of stock.
Can be built for your business
Fake-location checks, a site boundary (geofence), team groups, approving or rejecting reports, and a map of photo pins are not in our system today. All of them can be built, around how your team works.

Talk to me →Questions
Is this timestamp camera free?
Yes. Free, no ads, no app and no sign-up. The photo only carries a small 3thanwong.com line under the stamp.
Does it work on iPhone and Android?
Yes. Use Safari on iPhone or Chrome on Android, and allow the camera and location. It also works on a laptop with a webcam.
Are my photos uploaded?
No. The photo, coordinates and note are made in your browser and saved only on your own device. Our statistics only record that a photo was taken.
Can the time or location be faked?
Yes. A browser tool can't stop someone changing the phone's clock or using a fake-location app. For a team's work records, use a system that keeps its own records.
How do I add a map to the photo?
Switch on "Add map" before you take the photo. Your browser loads one map image of your area from OpenStreetMap, and it is stamped on the photo with "© OpenStreetMap contributors".
Why does the photo say "location N min old"?
The phone has not had a new location fix for a few minutes. The stamp says how old the location is, so whoever sees the photo knows.
