Revolut.me is Revolut's built-in payment-link page — anyone with the link (or a scan of it) can send you money without needing your account number or sort code. This generator just wraps your Revolut username into that link and turns it into a QR code.
It's a natural fit for tip jars, market stalls, freelance invoices, or splitting a bill with friends — print it once and reuse it, since the destination is your username, not a one-time transaction.
