Core concepts
TODO: carrier types, format specs, validation rules.
NOTE (填充時): 格式規格（手機條碼 / + 7 alphanumeric、自然人憑證 2 letters + 14 digits）
已在 tw-ecom-invoice-ezpay Gotchas 中詳細說明。此 skill 不重複格式規格；
改聚焦在 UX 層面：validation 在哪層做、錯誤訊息設計、掃碼元件選型。
Decision tree
TODO: which carrier to default to given context (e.g., 有會員帳號 → 會員載具；無帳號 → 引導填手機條碼；B2B → 不需載具).
Implementation guidance
TODO: scan widget 選型與整合、client-side validation 流程、member-carrier linking（會員帳號與手機條碼綁定）。
不重複 issue_invoice carrier_type / carrier_num 參數說明 — 那些在 ezpay/universalec skill。
