Dynamic PayNow
A PayNow QR generated per sale, carrying the exact amount, with a payment-success notification back to the merchant. That is the whole difference from a static sticker, and it is the difference between a payment the till confirms and a payment a staff member confirms by looking at a screenshot.
Why it matters to a merchant
The version that removes the two failure modes a counter actually suffers: the customer typing the wrong amount, and nobody knowing whether the payment landed. That is why it is a payments decision rather than a signage decision — the code is the same idea in both forms, and only one of them closes the sale without a staff member checking a phone.
