Here are a few situations where this can be useful.
Businesses may need to change the bank account or UPI ID they use to receive payments. Every QR copy then has to be found and replaced across counters and locations.
Old stickers are often torn off or covered with new ones, leaving layers, tape marks, and an untidy look.
With NoQR: they can update the UPI ID in one place by renaming the Wi-Fi hotspot, instead of finding and replacing every QR code.
A camera may not be working or may be broken, or the lighting may be poor.
With NoQR: finding the UPI ID does not use the camera or a QR code.
Restaurants and other businesses put real effort into creating beautiful tables, reception areas, and interiors. Yet copies of the same QR code often end up on every table or stuck across walls, which can make an otherwise thoughtful space look cluttered and become an eyesore.
With NoQR: one nearby Wi-Fi name can make the business’s UPI ID discoverable throughout that area, without placing a QR code on every table or wall.
A QR code may be stuck on a wall or near the pump, making it difficult to scan from inside a car. People may end up unlocking their phone and handing it to the attendant so the attendant can scan the QR code or enter a UPI ID.
With NoQR: the customer can find the station’s UPI ID from inside the car while the fuel is being filled, without needing the attendant to scan a code or repeat the ID. This saves time for the customer and attendant, helps the queue move faster, may save a little fuel from idling, and helps the transaction finish faster.
At some businesses, employees wear a printed QR code around their neck like an ID badge, carry a card or sheet of paper containing the UPI ID, or even write it on their hand so they can show it when needed. It is one more thing to carry, keep safe, and replace when the details change.
With NoQR: the UPI ID can be available through the nearby Wi-Fi name, so staff do not need to wear or carry a printed QR code or paper with them.
