Is it possible to embed an amount of BTC in a QR code to transfer to whoever scans it?
E.g. I create a QR code for .5 BTC from my wallet, send the QR code to someone (without knowing their BTC wallet address), they scan it using their wallet app and receive it?

Just add amount parameter to QR data:
bitcoin:1ArmoryXcfq7TnCSuZa9fQjRYwJ4bkRKfv?amount=0.005
use google chart to generate QR
if you are asking about auto sending bitcoin through QR so it's not possible.

Answer I received on Reddit:
Yes. Create a paper wallet at bitaddress.org; send any amount of bitcoins to the qr code on the left that has the word "SHARE" next to it. Then, you can send the qr code on the right, the one that says "Secret," to the person who you want to receive the bitcoins. If they scan that qr code, the one that says "secret," they can receive the bitcoins you sent to the "Share" qr code into their bitcoin wallet.
This answer isn't for this question. Giving anyone your private key of this address giving them the access to bitcoins in this address. – Adam – 2017-12-01T11:05:44.457
Yes, thats exactly what I want. You create a new wallet, transfer the BTC to it, embed private keys, then anyone can take that BTC. – ljenkins – 2017-12-03T00:17:43.167
That is to request an amount, not send an amount – ljenkins – 2017-12-01T08:37:24.697
