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.
  • Receipts — print and drawer-kick use the paired hardware.
  • Take payment — where the payment terminal would settle a live tender.
