HandoffCub / Safety standards

A pass that changes every 30 seconds.

A quick visual guide to what happens between a scan and a safe handoff.

Pass lifetime
30 seconds, then it rotates
Reuse
Refused after the first scan
Release record
Pass, guardian, staff, time
The pass

Six checks built into every pass

Rotation

The code rotates every 30 seconds

A screenshot goes stale when the pass refreshes.

Signature

The pass is signed, not just encoded

Edited or invalid codes are rejected at the door.

Scope

One guardian, one child

Each pass is tied to an approved guardian and child.

Single use

The first scan retires it

Used passes are refused and logged.

Session

It lives inside a signed-in session

Passes belong to a signed-in guardian.

Expiry

Left-open passes close themselves

Unused passes expire with the pickup window.

Release chain

Scan to handoff

  1. 01

    Pass verified

    Expired, used, or edited codes stop here.

    Then
  2. 02

    Guardian matched

    Match the pass to an approved guardian.

    Then
  3. 03

    Pickup rules applied

    Check permissions and pickup rules.

    Then
  4. 04

    Staff confirm

    Staff confirm; the handoff is logged.

If a check fails, staff stop and review. Scanning alone never releases a child.

If something is off

Stop, check, record

The pass is expired, or already used

It is refused and the attempt is logged.

The guardian is not on the child's list

No release is offered until permission is confirmed.

Somebody else is holding the phone

The pass name is shown. Staff make the final call.

A pickup is disputed next week

Check the pass, scan time, staff member, and release record.
