Open the UPI payment tab, enter your UPI ID and shop name, and leave the amount empty. Download the printable card and put it at your counter. ### How do I share my Wi-Fi password with a QR code? Open the Wi-Fi tab, enter the network name and password, then download the QR or a printable card. Guests scan it with their phone camera to join. ### Do I need an app to scan these QR codes? Usually not for Wi-Fi: recent iPhone and Android cameras can read it. For UPI, scan with any UPI payment app. ### Is my data uploaded or saved anywhere? No. The QR code is built in your browser and the page blocks network requests, so your UPI ID, Wi-Fi password and text never leave your device. ### How to create a UPI QR code for my shop? Enter your UPI ID and shop name, leave the amount empty, and download the card. Customers scan it with any UPI app and enter the amount themselves. ### How do I make a UPI QR code with a fixed amount? Type the amount in rupees, with up to two decimals. The code then carries am=, so most apps show that amount to the payer. ### What does a UPI QR code contain? It contains a upi://pay link with the payee's UPI ID (pa), name (pn), optional amount (am), currency INR (cu) and optional note (tn). It does not contain your PIN or bank login. ### Is it safe to share my UPI QR code? Yes, it only lets people pay you. Never scan a QR code or share your PIN to receive money, because that is how scammers take money out. ### How to share a Wi-Fi password with a QR code? Enter the network name and password on the Wi-Fi tab and download the QR. Print it or show it on screen so guests can scan it with their camera. ### Is it safe to put a Wi-Fi password in a QR code? The password is stored as plain text, so anyone who can see the code can read it. Use it where you are happy for people to join, ideally on a guest network. ### Which security type should I choose? Choose WPA / WPA2 / WPA3 for nearly all modern routers. Pick None only for an open network. ### Why does my Wi-Fi QR code not connect? Check the name and password match exactly, including capitals, and that hidden network is ticked only if the network is hidden. Some older phones need a QR scanner app. ### How do I make a QR code for a link? Paste the link into the Link / text tab. The QR updates as you type, then download it as PNG or SVG. ### Do these QR codes expire? No. The code holds the text itself rather than pointing to a service, so it works as long as the link or text is still valid. ### Which error correction level should I pick? M suits most uses. Choose Q or H for codes printed small or likely to get scratched, knowing the code gets denser. ### Can I change the colour of a QR code? Yes, but keep it dark on the white background. The tool warns you when the contrast is too low for scanners. ## Other free private tools by the same author - [Redact PDF](https://redact.umesh-malik.com/): Black out or blur names, numbers and any text.
