Issuing and Revoking Transaction QR Codes
Separately from the register QR code, you can issue a QR code for one specific past sale, just for that customer. Use it when a customer contacts you later asking for their receipt, or when they missed scanning after paying. This article explains how to issue one, and how to revoke it if you issued it by mistake.
What a transaction QR is
- A QR code for one sale — It shows only the receipt for the sale it was issued for. No other receipts are shown.
- Works once — Once the customer receives the receipt, the QR code stops working.
- Has an expiry — You set it in minutes when issuing. It starts at 1440 minutes (24 hours) and can be set up to 10080 minutes (7 days).
- Doesn't affect the register QR code — Issuing a transaction QR leaves the register QR code working as before.
Issuing one
- From the store menu, open "POS terminals" and choose the terminal the sale was made on.
- Open the sale from the transaction list. The five most recent sales can also be opened from "Latest sales" on the terminal page. Sales whose time for the register QR code has passed show an "Issue a per-sale QR" link.
- In the "Per-sale QR code" panel, fill in "Reason for issuing (optional)" and "Expires in (minutes)" if needed, then click "Issue QR".
- The QR code appears under "Active QR codes". Have the customer scan it on the spot, or click "Enlarge" to show it larger. Use "PDF" to print or send it.
How the customer can receive it
When the customer scans the QR code, they see the receipt and the options below. This page is currently shown in Japanese.
- LINEで受け取る (Receive in LINE) — The LINE Mini App opens and the receipt arrives in LINE.
- メールで受け取る (Receive by email) — The receipt is sent to the email address they enter. If the address has a mistake they are told right away, and the QR code stays usable. One address can receive up to three receipts an hour.
- このレシートを受取済みにする (Mark this receipt as received) — The customer checks what is shown on screen and marks it as received. The receipt is not saved or sent anywhere, and the same QR code cannot be opened again later, so suggest LINE or email to customers who want to look at it again.
Revoking one
If you handed it to the wrong customer or the URL was shared unintentionally, revoke it before the customer receives it.
- Open the sale, and under "Active QR codes" in the "Per-sale QR code" panel, click "Revoke" on the QR code you want to stop. You can also revoke it from the "Enlarge" screen.
- Confirm the prompt and the QR code stops working. This cannot be undone.
- If needed, you can issue a new QR code for the same sale.
A received receipt can't be taken back
You can only revoke a QR code the customer hasn't used yet. Once they have received the receipt, "Revoke" is no longer shown and the store can't take the receipt back. Check who you are giving it to before you issue it.
Record of issued QR codes
QR codes issued in the past are listed under "Issue history" in the sale's "Per-sale QR code" panel. Received, expired and revoked ones are shown with who issued them and when.
Good practice
- Check who you give it to — Anyone who has the URL can receive the receipt. Give it only in person, or to contact details you have confirmed belong to the customer.
- One QR code per sale — As a rule, issue only one for each sale.
- Keep the expiry short — If the customer will scan it on the spot, a short expiry is safer. You can revoke it as soon as it is no longer needed, without waiting for it to expire.
