I'm creating a Bitcoin QR link with my website, but I want to be able to just link to a page that generates the QR code with the current USD price equivalent of BTC in the QR. I tried blockchain.info, but it only displays the QR code and I can't embed a price into it. How can this be done? I'm trying to use it on checkout where I can pass in a BTC address + USD price to the QR code generator and the user can just pay the exact amount needed without having to lookup how much to pay.
I know bitpay does this, but they also log every transaction to the government. So I rather just use a service that doesn't log anything.
