Terminal payment setup

What you will learn

Connect a payment terminal so Cashier can take card payments (Card payment).

User checklist

1. Owner configures device in Dashboard → Settings → Devices (or Cashier Settings → Terminal).
2. Assign terminal to store and lane as required.
3. Vendor Desktop on lane must run for bridge/ECR (browser can poll status but terminal often needs desktop relay).
4. Test $0.01 or voidable sale in training mode.
