# Cashiers

A **cashier** is a person who operates a POS terminal. Each cashier has a name, a short code for identification, and a numeric PIN for logging in.

## Creating a Cashier

Navigate to **Dashboard > POS > Cashiers** and click **Create Cashier**.

### Required Fields

| Field          | Description       | Rules                                                          |
| -------------- | ----------------- | -------------------------------------------------------------- |
| **Name**       | Display name      | Free text (e.g., "John Doe", "Sarah")                          |
| **Short Code** | Unique identifier | 1-10 characters, letters and numbers only, stored as UPPERCASE |
| **PIN**        | Login code        | **8 or more digits, numbers only**                             |

### Important Rules

* **PIN is numbers only.** No letters, no special characters. Just digits.
* **PIN must be at least 8 digits** (e.g., `12345678`).
* **Each PIN must be unique.** No two cashiers can share the same PIN, because the system identifies cashiers by their PIN at login.
* **Short codes must be unique** per merchant.

## Short Code vs PIN (Important!)

> **Short Code** = A label. NOT secret. Shows in Order IDs and reports.
>
> **PIN** = A password. SECRET. Numbers only. Used to log in.

|              | Short Code                    | PIN                     |
| ------------ | ----------------------------- | ----------------------- |
| **What**     | A label / identifier          | A login password        |
| **Format**   | Letters + numbers (e.g. `JD`) | Numbers only, 8+ digits |
| **Secret?**  | No                            | Yes                     |
| **Used for** | Tracking in Order IDs         | Logging into terminal   |

**The short code is a label. The PIN is a password.**

## Managing Cashiers

### Edit a Cashier

You can change:

* Name
* Short code
* Active/inactive status

You **cannot** view a cashier's current PIN. PINs are hashed and cannot be retrieved.

### Reset a PIN

If a cashier forgets their PIN:

1. Go to **Dashboard > POS > Cashiers**
2. Click the cashier's menu and select **Reset PIN**
3. Enter a new PIN (8+ digits)
4. The cashier's old PIN no longer works
5. All active sessions for that cashier are terminated

### Deactivate a Cashier

Deactivating a cashier:

* Prevents them from logging into any terminal
* Ends all their active sessions
* Does not delete payment history
* Can be reactivated later

## Cashier Accountability

Every payment created by a cashier is tracked via the Order ID:

```
POS-R1-JD-1707842400000
         ^^
         Cashier short code
```

This means merchants can:

* See which cashier processed each payment
* Filter payment history by cashier
* Audit cashier activity across terminals
