The shop ask you to send a copy of your ID in order to "secure" the order. No one should ever send their ID information to some random shop. There are lots of credit card authorization apps for that purpose available.
They did not give any reason for not using credit card authorization, like all the trustworthy shops do, instead of asking for a copy of your ID. If you are ready to send that information to an anonymous shop in China, go ahead and do that. If not stay away from this shop.
They say, that their reputation is "solid" . Please read the other reviews and decide yourself how solid it actually is. There are much more secure and professional options available even with a bit lower prices.
