# Order IDs

Every POS payment gets a unique **Order ID** that identifies where, who, and when the payment was created.

## Format

```
POS-{terminalCode}-{cashierCode}-{timestamp}
```

### Components

| Part           | Description                                     | Example         |
| -------------- | ----------------------------------------------- | --------------- |
| `POS`          | Fixed prefix indicating a point-of-sale payment | `POS`           |
| `terminalCode` | The terminal's short code                       | `R1`            |
| `cashierCode`  | The cashier's short code                        | `JD`            |
| `timestamp`    | Millisecond timestamp (epoch)                   | `1707842400000` |

### Example

```
POS - R1 - JD - 1707842400000
 |     |    |    |
 |     |    |    └── Timestamp: Feb 13, 2024 at 16:00:00 UTC
 |     |    └─────── Cashier: JD (John Doe)
 |     └──────────── Terminal: R1 (Register 1)
 └────────────────── POS payment
```

### Breakdown

| Part     | Value           | Meaning                   |
| -------- | --------------- | ------------------------- |
| Prefix   | `POS`           | It's a POS payment        |
| Terminal | `R1`            | Terminal "Register 1"     |
| Cashier  | `JD`            | Cashier "John Doe"        |
| Time     | `1707842400000` | Feb 13, 2024 at 16:00 UTC |

## Why It Matters

The Order ID creates an **accountability trail**:

* **Which terminal?** The terminal short code tells you which register/location.
* **Which cashier?** The cashier short code tells you who processed the payment.
* **When?** The timestamp gives the exact moment of creation.

## Using Order IDs

### In the Dashboard

Order IDs appear in:

* Payment history list
* Payment detail views
* Search results (you can search by Order ID)

### For Auditing

Filter or search payments by:

* Terminal code (e.g., find all payments from `R1`)
* Cashier code (e.g., find all payments by `JD`)
* Date range using the timestamp portion

### For Customer Support

If a customer has a payment issue, ask for their Order ID. It immediately tells you:

* Which terminal processed it
* Which cashier was responsible
* The exact time of the transaction

## Uniqueness

Order IDs are guaranteed unique because:

* The timestamp is in milliseconds
* Combined with terminal + cashier codes, collisions are practically impossible
* Each payment also has a separate system-generated `paymentId` (UUIDv7) as a primary identifier
