Photo Verification For Site Records
KANNA’s Photo Verification feature stamps your site photos with the date, time, GPS location, and address, burned directly onto the image as they are captured. When the Photo stamp switch is turned on, photos taken with the in-app camera also carry a verification mark in the photo list and detail views, so you can tell at a glance which images were captured on site in KANNA and which were brought in from elsewhere. The date and time come from KANNA’s server, not the device, so changing a phone's clock or timezone has no effect on the stamp. It is a simple, reliable way to keep genuine site captures clearly identifiable across construction, civil engineering, and facilities projects.

Site Photos You Can Trust On Sight
When the Photo stamp switch is on, every photo taken with the KANNA in-app camera is stamped with the date, time, GPS location, and address, and carries a verification mark in your photo list and detail views. That mark is a clear signal: this image was captured on site in KANNA, with a server-verified timestamp. Instead of wondering where a photo came from or when it was taken, your team can see the genuine in-app captures straight away and get on with the job.

Which photos get the verification mark?
The mark is applied to photos taken with the KANNA in-app camera when the feature is enabled for your account, the Photo stamp switch is turned on, and location permission is granted. When those conditions are met, the photo is stamped with the date, time, location, and address, and carries the verification mark in your photo list and detail views. A few in-app photos are not stamped by design, including captures taken in chat and photos using the electronic blackboard, where the blackboard takes priority. Photos brought in from a camera roll or added by photo selection are not stamped either, so the mark stays a reliable signal that an image was captured on site in KANNA.
Does Photo Verification work offline?
No. The verification mark needs an online connection, because the date and time are pulled from KANNA’s server rather than the device. This is what makes the timestamp reliable, since changing a phone's clock or timezone has no effect on it. If the server date and time cannot be retrieved, the photo shows "- -" and no verification mark is applied. To capture stamped photos, your device needs to be online at the time of capture.
