★ THE #1 RULE · 最重要守則

Every sale goes on the POS first. Payment is taken on the Oasis terminal.

每一筆銷售都要先在 POS 登記，收款一律用 Oasis 刷卡機。

The Mr.DoNothing POS records the sale and reduces stock. All payments — card, Octopus, e-payment — are taken on the Oasis card terminal. We do not accept cash. Do both for every customer: ring it up on the POS and take payment on the terminal.

Mr.DoNothing POS 負責記錄銷售與扣庫存；所有付款（刷卡、八達通、電子支付）一律用 Oasis 刷卡機收款。不收現金。每位客人兩件事都要做：POS 登記 + 刷卡機收款。
1️⃣ Ring it upon Mr.DoNothing POS在 POS 登記
→
2️⃣ Take paymenton the Oasis terminal用 Oasis 刷卡機收款
→
3️⃣ Hand overbag the item交付商品 + 裝袋
👉 We accept card / e-payment only. On the POS, always press 💳 Card (incl. other). Every payment settles through Oasis, so it always counts as Card. 👉 只收刷卡／電子支付。在 POS 上一律按「刷卡 (含其他)」。所有付款都經 Oasis 結算，因此一律算「刷卡」。
🚫 No cash. We do not accept cash. If a customer only has cash, politely explain that we take card, Octopus, or e-payment only. Never press the 💵 Cash button. 🚫 不收現金。若客人只有現金，請禮貌說明我們只收刷卡、八達通或電子支付。請勿按「現金」鈕。

Why it matters: at closing, the POS "Sales by payment" total must match the Oasis terminal card report. If you press the wrong button, the numbers won't reconcile. 為什麼重要：結算時，POS 的「付款方式別銷售」要對得上 Oasis 刷卡機的刷卡報表。按錯按鈕，帳就對不起來。

Make a sale 完成一筆銷售

Payment method
▲ Payment method / 付款方式 — card & e-payment = Card (incl. other); cash = Cash (blue = selected)
⛔ Never skip the POS, even when busy. If you only take money on the Oasis terminal without ringing it on the POS, the stock and sales records will be wrong. ⛔ 再忙也不能跳過 POS。只用 Oasis 刷卡機收款卻沒在 POS 登記，庫存與銷售紀錄就會出錯。
💡 The order of buttons on the POS is just recording. Whether you tap the Oasis terminal before or after pressing Complete Sale is fine — but both must happen for each customer. 💡 POS 只是記錄。刷卡機在「完成銷售」前後刷都可以，重點是兩件事每位客人都要做。
🧾 Our POS does not print a paper receipt — it keeps a digital record with a receipt number. For card payments, the Oasis terminal prints the card slip. 🧾 我們的 POS 不印紙本收據，只保留含收據號碼的電子紀錄。刷卡時由 Oasis 刷卡機列印簽單。
💵

Cash payment — received & change 現金收款 — 收現與找零

⛔ Only for pop-ups that accept cash. If your pop-up is card-only (e.g. Hong Kong — Oasis terminal), never use Cash. ⛔ 僅限接受現金的快閃店。若你的店只收卡（例如香港用 Oasis 刷卡機），請勿使用「現金」。
  1. Tap Complete Sale / 完成銷售, then choose 💵 Cash / 現金 — a cash panel appears in the same popup. 按「完成銷售」後選「💵 現金」— 同一視窗會出現現金面板。
  2. Enter the amount the customer handed you in Cash received / 收到現金 — type it, or tap a bill chip (e.g. +NT$1,000) once per bill as you count. Exact / 剛好 = exact amount, C = clear. 在「收到現金」輸入客人給的金額 — 直接輸入，或邊數鈔邊按面額鍵（如 +NT$1,000，每張按一次）。「剛好」= 剛好收足，「C」= 清除。
  3. Change / 找零 is calculated instantly and shown big in green — hand back exactly that amount. 「找零」立即計算並以綠色大字顯示 — 照金額找零即可。
  4. If the cash is not enough, a red "… short / 不足 …" appears and Confirm / 確認 is blocked — ask the customer for the rest first. 若現金不足會出現紅字「不足…」且無法按「確認」— 請先向客人補收。
  5. Tap Confirm / 確認. The change amount is shown once more in the green ✓ toast after the sale. 按「確認」。銷售完成的綠色 ✓ 提示會再顯示一次找零金額。
💡 Entering the received amount is optional but strongly recommended — it is saved with the sale record. If the cash drawer doesn't match at day close, the office can trace exactly which sale went wrong. 💡 「收到現金」非必填但強烈建議輸入 — 會隨銷售紀錄一起保存。日結算現金對不上時，公司可追查是哪一筆出錯。

💳 Card refund = also refund on the Oasis terminal. The POS refund only fixes our records & stock. You must return the money to the customer on the Oasis terminal, to the same card they paid with. Card only — we never refund cash. 💳 刷卡退款＝也要在 Oasis 刷卡機退。POS 退款只更新我們的紀錄與庫存；實際退錢要用 Oasis 刷卡機退回原本付款的那張卡。只退卡—絕不退現金。
⚠️ Refund policy: there is no manager on site, so you can process the refund yourself — no need to wait for approval. Always pick the correct refund reason (required); that is your record. Every refund is logged under your name with the reason and time, and the team reviews refunds afterwards. For a full cancellation, drop a quick note in the LINE group afterwards. Only if you are genuinely unsure whether to refund, ask in the LINE group first. ⚠️ 退款政策：現場沒有負責人，所以你可以自行處理退款，不必等待核准。務必選擇正確的退款原因（必填），這就是你的紀錄。每筆退款都會記在你名下並附原因與時間，團隊會事後檢視。整筆取消後請在 LINE 群組簡短告知。只有真的不確定是否該退時，才先在 LINE 群組詢問。

Sold out · product not found 售完 · 找不到商品

Situation / 情況What to do / 怎麼做
Shows "Sold out / 售完"顯示「售完」 Stock is 0 on the POS. Check the shelf/storage — if you find stock, tell the manager to add it. Do not sell without ringing it up.POS 庫存為 0。查看貨架／庫存，若有貨請通知負責人補登；沒登記不要賣。
Scan finds nothing掃描找不到 Try typing the product name. Turn on Incl. unstocked / 含未入庫 to search all products. If still missing, ask in the team LINE group — don't invent a price.改用商品名搜尋；開啟「含未入庫」搜尋全部。仍找不到就在團隊 LINE 群組詢問，別自行定價。
A "Register product" popup appears跳出「新增商品」視窗 Scanning an unknown barcode pops up a "Register product" form. Do NOT fill it in. Tap Cancel and ask in the team LINE group — a wrong price/barcode breaks the records.掃到未登錄的條碼會跳出「新增商品」表單。請勿填寫，按「取消」並在團隊 LINE 群組詢問；錯誤的價格／條碼會破壞紀錄。
Price shows 0 / "No price"價格為 0 ／未設價 The HKD price isn't set. Call the manager to set it in Admin — do not sell at a guessed price.港幣價格未設定。請負責人在管理端設定，勿以猜測價格販售。
💡 There is a ➕ button to register a product on the spot, but only the manager should use it — a wrong barcode or price breaks the records. 💡 有 ➕ 現場新增商品的按鈕，但只由負責人操作；條碼或價格錯誤會破壞紀錄。

Close the day 日結算（收店）

At the end of each day, before you leave: 每天收店前：

  1. Tap 📅 Close day / 日結算. 按「日結算」。
  2. Review Sales by payment / 付款方式別銷售 — the Card total is the day's sales (Cash / Other should be 0). 檢視「付款方式別銷售」—「刷卡」合計就是當日銷售（現金／其他應為 0）。
  3. Reconcile the card total with the Oasis terminal's daily card report. They should match. 把刷卡合計與 Oasis 刷卡機的當日刷卡報表核對，應一致。
  4. Since we take no cash, the POS shows 💵 No cash activity — skip cash check. No cash counting needed. 因為不收現金，POS 會顯示「無現金交易 — 略過現金核對」，不用清點現金。
  5. Tap ✓ Confirm close / 確認結算. You'll see ✓ Day closed (awaiting admin approval). 按「確認結算」。會顯示「結算完成（待管理員核准）」。
Close day
▲ Close day / 日結算 — the Card total = the day's sales. Card-only, so it shows "No cash activity".
✅ After confirming, the manager approves it in the admin panel. Because we take no cash, there is nothing to count — just check the Card total matches the Oasis terminal. ✅ 確認後由負責人在管理端核准。因為不收現金，無需清點 — 只要確認「刷卡」合計與 Oasis 刷卡機一致即可。

Check out 下班簽退

  2. Confirm the cash if prompted, then Confirm check-out / 確認下班. 如有提示先確認現金，再按「確認下班」。
