Show a QR code and take payment by UPI
No change in the box, no loose coins to hunt for. The customer scans and pays.

What the QR code works with on a cart, in a dhaba and behind a medicine counter
UPI payments
At the cart's morning rush, one customer scans while the next has his limes weighed, so the queue moves at the pace of the scale and not of the change.
Bills on your phone
The limes, the plate of dal and the strip of tablets each get a short bill on the same phone as the QR code, for the customer who asks for one.
Daily reports
At closing, the fruit seller reads the day's sales from the phone and does not have to count a box full of small notes first.
Credit book (khata)
The family that settles the dhaba's bill every Saturday scans the code when it clears its page.
Low stock warnings
At the night medicine counter, a look at the list shows the strips close to finishing before the next customer comes in with a prescription.

The twenty-rupee sale, the midnight truck and the medicine counter at closing
Change for a hundred-rupee note on a fruit cart
A customer picks two limes and a few bananas, and the sale comes to a small round amount. He holds out a hundred-rupee note. You have no change, the next customer is waiting, and one of you has to go to the tea stall to break it. Many small sales a day each lose a minute that way. The next customer sees the queue and walks on to the next cart.
The truck driver who arrives after the dhaba's cash is counted
Trucks pull in late at night, and a driver eats a plate of rice and dal and wants to pay. The cash box was counted and put away an hour ago, and the one note in his pocket is too large. Waiting for change at that hour costs you the next table.
The last strips go for large notes and the small change is gone
At midnight the chemist's box holds the day's tens, and the customer holds a large note for one strip. By the third such sale the box cannot make the change, and the customer with the large note waits while the owner counts the box.


Where the QR code sits at a cart, a dhaba and a chemist
A QR code on the cart's bamboo pole
Stick the code where the customer's eye falls as the scale settles. He scans, pays the exact amount for the limes and the bananas, and shows you the screen. No change, no walk to the tea stall, and the customer behind him steps forward at once.
A code on the dhaba counter for the midnight plate
The driver scans the QR code on the counter beside the pots and pays for his plate. The cash box need not be opened, and you do not wait for him to find the right note. The table is free for the next truck.
The chemist at midnight, with no change in the drawer
By midnight the small notes in the drawer are gone, and a customer with a prescription holds out a large one. Show the QR code. He pays the exact amount for the strip, the bill is made on the same phone, and the drawer holds only what cash came in.
Questions from shops where the sale is small or the hour is late
A customer pays only a small amount. Do I lose something on the payment?
The finance ministry said in September 2026 that a payment to a seller of up to ₹2,000 stays free of fees on the seller's side under the UPI framework. For a cart or a counter, that means no fee on a payment of that size.
My cart takes more UPI in the festival month. What do I read before I ask my bank about fees?
Read the month's takings on your phone first. The daily report adds up each day of the festival weeks, with UPI and cash apart. The finance ministry said in September 2026 that small shops receiving up to Rs 1 lakh a month through UPI QR codes pay no fee on those payments, so ask your bank with the month's UPI figure in your hand.
A customer's payment looks stuck. Do I hand over the goods?
Wait until the customer shows you the paid screen, as you would wait for a note to be checked. Then hand over the goods. If he cannot show it, he can pay again or pay cash.
A customer pays more than the bill by mistake. How do I return the difference?
Give it back in cash, or send it to him by UPI from your own phone, as you would to anyone. Tell him what you returned so that he is not left wondering, and he goes away sure of what he paid.
Where do I put the QR code so that customers find it?
Where the eye falls as the customer is paying: on the pole of the cart, on the counter beside the pots, on the glass of the medicine counter. Keep it on your phone as well, for the customer who stands at the side.
QR codes and UPI users in India, in numbers
As of 2024-25, 56.86 crore payment QR codes had been deployed to about 6.5 crore sellers across India, says the finance ministry. A QR code on a pole, a counter or a cart is by now one of the ordinary things a customer looks for.
About 55.49 crore users were onboarded on UPI by June 2026, NPCI informed the government. The person at your cart or counter is more likely to have UPI on the phone than not.
