How does a photo request reach a worker?

By the LockProof Team · Last updated November 11, 2026

A photo request goes out as a text, a WhatsApp message or an email with one link, on the channels set on the worker’s assignment. For a job on your schedule, the check is created on the server before the link goes out, and the photo is filed against it. The worker needs no app and no account.

What happens, step by step

  1. You set the worker’s assignment: the site, the hours, and a random or a fixed schedule.
  2. At each send time, LockProof issues one link for the check it already holds on the server.
  3. The link goes out on each channel on the assignment. A channel the worker opted out of is skipped.
  4. The default text reads “Hi [name], please [task] at [site]. Submit a live photo:” and then the link.
  5. The worker taps the link and takes the photo through the phone’s camera.

Sending one right now

You can also send a check on the spot. Send Reminder on a worker’s row creates a check and sends the same text a scheduled check uses.

When the worker’s assignment belongs to a Round, which groups several sites under one message, Send Reminder sends one message for the whole Round instead, after a confirm dialog that says so.

Common questions

Does the worker need to download anything?

No. The link opens in the phone’s browser. There is no app to install and no account to create; the link itself is what is checked.

Can one check go out on more than one channel?

Yes. It is sent on every channel set on the assignment, with the same link on each.

Opening 0:00

A manager worries the crew won’t use another app. A worker just wants to do the job. Here is everything a worker sees: a text, a camera, and a done screen.

The text 0:11

It starts with a text. There is no app to download, and no password to remember.

The photo 0:17

One tap opens the camera. It takes a live photo, in the phone’s browser. The photo library is blocked.

On the record 0:25

They tap Submit, and it is on the record. Our server sets the time when the photo arrives. The phone asks to share its location, and the office can require it.

On their own 0:36

Something nobody scheduled still gets a record. A worker’s own link logs a photo any time. It is marked as theirs, and kept out of the compliance numbers. LockProof. Know the work got done, without calling anyone. See it for your own crew at lockproof.com.
