A good scan-to-pay sign does more than show a QR code. It tells customers who they are paying, so they notice when something is wrong. The PromptPay QR page on QRnaka has a Printable card that lays out such a sign for you: free, no sign-up, no design software.

What goes on the card

  • Heading: "Scan to pay" by default. Type your own (up to 40 characters) or pick a suggestion such as "Pay here".
  • Shop name and logo: optional, but they show the sign is yours.
  • The QR code, with the line "Scan with any Thai bank app".
  • Amount: only when the code has one.
  • Account name: the name customers will see in their banking app after scanning.
  • A check line: "Before you confirm, make sure your app shows this account name". Without an account name it asks payers to check the payee's name instead.

The account name is the line that matters most. A QR code only carries a number; the payee's real name appears in the banking app. If someone sticks a different code over your sign, the name in the app will not match the card, and an attentive customer stops before paying.

Your PromptPay number is printed only if you tick "Also show the PromptPay number" (off by default). The card has no bank or PromptPay logos; add your own shop logo instead.

The card's fixed wording follows the site language. With the site in English you get an English card; press TH at the top for a Thai one, which many Thai customers will find easier.

Step by step

  1. Open the PromptPay QR page and enter your PromptPay number. For a counter sign, leave the amount empty so customers type it.
  2. Scroll to "Printable card" and switch on "Make a printable card".
  3. Set the heading, shop name and "Account name the bank app shows".
  4. Choose whether to show the number, add a logo (PNG, JPG or SVG) and pick a card colour.
  5. Choose a size: A6 (10.5 × 14.8 cm), A5 (14.8 × 21 cm) or business card (9 × 5.5 cm).
  6. Choose the paper: "On A4" fits four A6, two A5 or ten business cards per sheet with dashed cut lines; "Card-size page" puts one card per page, which is what a print shop wants.
  7. Watch the badge on the preview. The whole card is drawn and its QR read back. "Scans" means go ahead; otherwise try stronger colours or less decoration on the code.
  8. Download the PDF, PNG or SVG, or press Print.

To get the account name exactly right, scan your code with your banking app, note how the confirmation screen shows the name, type it the same way, and cancel.

Which size?

A business card fits beside the till, A6 is the usual counter size, and A5 is easier to spot on a wall. Not sure? Print one A6 on plain paper, put it where it will live and scan it from where customers stand. More in why a printed QR won't scan.

Printing tips

  • Print at actual size (100%), never "fit to page", or the card changes size and the cut lines drift.
  • For a print shop, send the PDF made with "Card-size page".
  • Thick paper or card lasts longer on a counter.
  • Matte lamination reduces glare; glossy finishes and clear acrylic can reflect lights, so test under your shop's lighting.
  • Keep tape and stickers off the code, especially the three large corner squares.

Test the printed sign

Scan the real sign with one or more banking apps, from where customers stand. Check the account name matches the card and the amount is right, then cancel. To see the number inside, photograph the sign and open it on the Read QR page, which reads on your device and uploads nothing.

After that, check the sign now and then, and straight away if it looks different, for example with a sticker on it. See checking a PromptPay QR before paying.

Where the card details go

The shop name, account name and logo stay in the page on your device; if you are not signed in, they are not sent anywhere. If you are signed in, downloading or printing keeps the card file in your account history. Your browser remembers the size, paper and colour, but not the names.

FAQ

Is the printable card free?

Yes. It is part of the PromptPay page: no sign-up, no ads.

Should I print my PromptPay number on the sign?

You don't have to. The number is inside the code anyway and anyone with a QR reader can see it. Printing it helps people who prefer to type it, but think twice if your PromptPay ID is a citizen ID.

Can I make the same card for TrueMoney or bill payment?

No, the card is only on the PromptPay page. For other codes, use "Frame and label" under "Style" to put text around the code, then lay it out yourself.
