Features

Every shift, supervised by the system.

Seven features work together from check-in to check-out, so the business can see the shift is covered and the officer can prove the work was done.

One system. Seven ways to supervise a shift.

Each feature does one job. Together they cover the shift from the moment an officer arrives to the moment the record closes.

Proof the right officer is really there.

Two checks run at check-in. Both must pass, or there is no check-in.

03Face Scan

Matched at check-in. Checked again during the shift.

A face scan is compared with the officer's verified face. It stops one person checking in and handing the shift to someone else.

  • Face scan at every check-in
  • Face checks during the shift
  • Used only with clear consent
  • Every check logged with its result

During the shift

Live from check-in to check-out.

While the shift runs, both sides stay in view and in touch.

  • Starts at check-in
  • Stops at check-out
  • Alert when an officer leaves the boundary

Understood. I will lock it at 23:00 and confirm.

Thank you.

Call is one tap away

05Chat and Call

Talk inside the shift, where it is recorded.

Every shift has its own chat for the officer, the business and the Zelver team. When a message is not enough, a call is one tap away.

  • One chat for every shift
  • Officer, business and Zelver team
  • Call with one tap
  • Kept in the shift record

After the shift

A fair close, written down.

When the officer checks out, the system closes the shift. Time is measured, both sides are rated and the record is kept.
