So as when your bitcoin address is requested you can just send the image for scan to prevent your Bitcoin address from being tempered with. I also thought of how easy it would be for businesses that uses Bitcoin as payment method. It could be printed out and pasted on points where it can be scanned easily.
This idea seems risky and might just be the worse idea, mate. Generating QR codes off wallets? Did you know that hackers could compromise QR codes using this method? They might replace your wallet address with theirs, so when someone scans the code, the funds go to the hackers. It becomes tricky to verify if the QR code matches your wallet address. Cold, hot wallets, and exchanges usually have built-in QR codes for your wallet address, making it safer to send and receive money, preventing malware or clipboard viruses.
When you share your wallet address online and use a website to generate a QR code, you're exposing yourself to a bigger risk. QR codes may seem secure, but they can be altered by hackers or thieves. Sending them online will put you i a whole much risk. If you're receiving funds using a QR code, make sure to double check the details of the sender to avoid falling victim to scams.
