I guess you sweep the BTC first, then move the BTC to a new address, then use the same private key to claim BCH?
Yes the small round underneath the holo has a QR code aswell as the private key written. It is some sort of compressed key though, they all started with an S and there was significantly less numbers/letters in the key.
You always move your BTC first before claiming your BCH, I don't trust the program I was using so if I lost anything it would have just been the BCH if the program was malicious. It's super easy to use electron cash(PC) and just select keys -> import and you input the private key and it grabs your BCH and you ship it straight over to bittrex and dump immediately for btc.
I ran malwarebytes before and after using and removing electron cash and it didn't come up with anything. It's just a .exe and as far as I know doesn't install anything on your pc as you can't find it in add remove programs.. you just delete the .exe when you're done. Someone better at computering might be able to chime in on that.
