Why PIN sign-in matters
When multiple people share a POS device, audit trails fall apart unless the system knows *who* rang each sale. Wemu POS requires a 4-digit PIN for every staff member — cashiers, baristas, servers, owner — so every order, edit, and refund is stamped with who did it.
Setting a PIN
Each team member sets their own PIN:
- On the web dashboard, go to Team → pick a member → PIN code and set a 4-digit code
- Or the team member can do it themselves from Profile → PIN code on any device
PINs do NOT have to be unique across the team. Two people can both use `1234` — the lock screen picks the staff first, then validates the PIN against that person specifically.
Signing in at the till
- On the Wemu POS lock screen, tap your photo from the staff grid
- Enter your 4-digit PIN
- Choose what you want to do next:
- Clock in — start your shift timer (captures location if enabled)
- Clock out — end your shift
- Start / End break
- Skip — go to POS — jump straight to ringing sales without changing clock state
Who gets stamped on each action
| Action | Stamped with |
|--------|-------------|
| Order created | `staffId` of the signed-in staff |
| Refund processed | `staffId` of whoever ran the refund |
| Order edited | `updatedByStaffId` (keeps the original order's staff intact) |
| Cash in / out on the drawer | staff name + timestamp |
You can see the full audit log in Reports → Audit on the web.
Handing off the till
Tap the lock icon next to the profile name on the top-left of the POS home. The screen returns to the staff picker — next person picks their face, enters their PIN, and every subsequent sale is now stamped with them.
