Static vs dynamic UPI QR codes

A static UPI code omits the amount, so the customer types it — that is the printed shop standee, generated once and used forever. A dynamic code sets am for a specific transaction and is shown on a screen. Printing a fixed amount is almost always a mistake.

The difference

	Static	Dynamic
`am` parameter	absent	present
Where it lives	Printed standee	Screen or receipt
Generated	Once	Per transaction
Amount entered by	The customer	The merchant's system
Cost	Printing only	Integration

Why a printed fixed amount is a mistake

The code is permanent; your prices are not. A standee reading "₹120" becomes wrong the first time you change the price, and you cannot recall the ones already on the counter.

Print a static code with no amount, and put the price on the menu where it belongs.

The exception is a single-price context that genuinely cannot change without new signage — a fixed donation tier, a single-item vending point, a parking bay with a posted rate.

Where dynamic codes earn their place

Point of sale, where the till displays a code for the exact bill. Removes typing errors on larger amounts, which is where errors actually cost something.
Invoices, with tr set to your invoice number so reconciliation is automatic.
Ecommerce checkout, where the amount is known and the order id can ride in tr.

The tr parameter is what makes dynamic codes worth the integration: your settlement report comes back with your own reference on it.

Bulk static codes

If you need many static codes — per table, per room, per delivery agent — encode a distinct tn or tr per code so settlement tells you which one was used:

upi://pay?pa=shop@upi&pn=Chai%20Point&cu=INR&tn=Table%2007

Generate them from a CSV with our bulk tool, which decode-verifies each one before you print a hundred table tents.

Printing the standee

4 cm minimum of code for a 40 cm counter distance.
Error correction M; Q only if you are adding a logo.
Matt laminate. Gloss under a ceiling light is the classic counter failure.
Print the VPA and business name as text alongside — it gives a fallback when a camera struggles, and it is a fraud check.

FAQ

Should my shop's printed UPI QR code include the amount?

No. Leave the amount out so the customer enters it. A printed fixed amount becomes wrong the moment your prices change, and you cannot recall the standees.

What is the difference between a static and dynamic UPI QR code?

A static code omits the am parameter and is printed once; a dynamic code sets a specific amount per transaction and is normally shown on a screen.

How do I tell which table a payment came from?

Give each table's code a distinct tn or tr value. That value appears in your settlement report.

Do dynamic UPI QR codes cost money?

The code itself does not. Dynamic use implies a point-of-sale or payment-gateway integration, which is where any cost lies.
