QR code to request payments

Does Solana define its QR code standard, where I can generate a QR code embedding my address, the amount, and the currency type (e.g., USDC)? Then whoever scans the QR code with a Wallet app can send money to me?

I know both Bitcoin and Ethereum support it, but have yet to find relevant references for Solana.

well thanks for reminding me, i have a new wallet that will let you stake to any node or pool and we will then push a standard onto the table for you chief
