# Peripherals

> Pair and manage the till's hardware — printer, scanner, cash drawer and payment terminal.

The **Peripherals** screen is the hardware pairing and diagnostics area for the till.
It manages the paired fleet and lets you test each device.

## Pairing the fleet

The screen has two sections:

* **Paired devices** — each shows its status, with reconnect / unpair controls and
  per-device actions such as a test print or a drawer kick.
* **Available devices** — devices you can pair.

Pairing and status run through the shared hardware layer. For the pilot this is the
in-memory mock fleet; concrete native / WebUSB drivers are a later wave.

## Payment-terminal self-test

A payment-terminal (TPE) card runs a sandbox authorize→capture / authorize→void
round-trip against the backend terminal routes (`/v1/payment-terminal`), reading the
active PSP provider configuration. The self-test never touches a live checkout
tender. With no backend configured, the card shows an offline fallback.
