Converting a cryptocurrency wallet sending or receiving address into a QR code format is an easy way of making or receiving payments. Many cryptocurrency wallets and apps support the scanning of QR codes. You can create your wallet QR code for scanning by entering a public wallet address into the field above and pressing the generate your QR code button. Once generated you can download it and save it for use on a website or send it to your friends.

I've created a Monero QR-Code Generator as a public service for people to use. There's no address checking, but it'll always give you back the address you put in!
