Server-trusted time
The time on the stamp comes from a trusted clock synced with our servers, not the phone clock. Changing the device time does not change the capture time.
The verification camera for field teams
Every field photo becomes proof anyone can check.
SnapID Mark stamps trusted time, GPS, address, weather, a mini map, a SnapID code and a QR onto every photo. Recipients scan the QR to see when and where it was taken, and whether it was altered.

Features
Everything a photo needs to be believed
Open the app and you are already in the camera. All verification details are burned onto the photo and stored for comparison.
GPS, address & mini map
Coordinates, accuracy, a full street address and a small map right on the photo. Mock locations are detected.
Weather at capture
Temperature and conditions are added automatically, handy for site diaries and claim files.
SnapID code + verification QR
Each photo gets a unique code like SNP-XXXX-XX. Anyone can scan the QR or enter the code to verify it, no account needed.
Photo clock-in
Clock in and out with a single photo, checked against the geofence of each site or location.
Shoot without signal
Photos queue safely on the device, keep their trusted time and upload automatically once you are back online.
Stamps in your style
6 built-in templates, a drag-and-drop editor, stickers, signature, notes, opacity, photo filters and landscape capture.
Vietnamese & English
The interface and stamp labels follow the photographer’s language. Light and dark themes included.

Inside geofenceCông trình Q.7 · 38 m
Offline & security
Hard to fake. Unbothered by bad signal.
The server is the source of truth: every upload is re-checked and flagged when something looks off.
Offline queue
Basements, remote sites: photos stay safe on the device with pre-issued SnapID codes and upload once a connection returns.
Trusted time that ignores clock changes
A monotonic system clock counts from the last sync, so changing the phone time has no effect.
Mock GPS & tampered device detection
Mock locations, rooted / jailbroken devices and invalid app builds are recorded as integrity flags.
File comparison with SHA-256
The verification page fingerprints the file inside the recipient’s browser, with no upload needed.
Private by default
The public verification page only shows a rounded area; full details stay inside your workspace.
Stamp templates
Made for every kind of job

FAQ
Frequently asked questions
Is SnapID Mark free?
Yes. Personal use is free. Every business workspace includes 5 free seats; when you need more, choose a 10, 25, 50 or 100 seat plan.
How do recipients verify a photo?
Scan the QR on the photo or enter the SnapID code at snapidmark.com/v/CODE. No account needed. The page shows the capture time, area, workspace, integrity flags, and lets you compare a file with the original right in the browser.
Can I shoot without a connection?
Yes. Photos are still stamped with trusted time and a pre-issued SnapID code, wait in an on-device queue and upload automatically when you are back online. There is a Wi-Fi-only upload option.
What if staff change the phone clock or use a fake GPS app?
The stamp time does not come from the phone clock, so changing it has no effect. Mock locations, rooted / jailbroken devices, clock drift and photos outside the geofence are flagged for managers to review.
Can one account work for several companies?
Yes. You have a personal workspace and can join several business workspaces, switching between them right from the camera screen.
Where do businesses manage everything?
In the web dashboard at app.snapidmark.com: members, sites and geofences, attendance, photo review, required templates, audit log and exports. Some management actions are also available in the app.
Who can see my photos?
Photos in a business workspace are visible to that workspace’s admins. People with a SnapID code only see the verification page with a rounded area. Details in our Privacy Policy.
How do I delete my account?
In the app: Settings → Account → Delete account. Or on the web via the Delete account page.
