That's very interesting. This transaction was actually using my phone. Usually I do most purchases on my laptop.
I just looked in my wallet on my phone and yes the offending card is in there. I don't ever recall putting it there as I usually just use the wallet for downloading concert tickets, boarding passes etc. I have since removed it, although the CC card is now cancelled anyway.
Also interesting, the name the Chinese company had was not my full first name, as it appears on my credit card, but a shortened version which is in my email.
