If you were buying something expensive like a used car or anything that costs you more than $1,000, do you think you have a right to see the original ID card of the seller and not settle for a business card that only has a name like "Ben Chen" or "Gloria Wu" or "Lawrence Liu" and a mobile number on it?  I mean, if the deal turns out to be a fraud the cops would just laugh at you if you can't tell them the legal name of the guy/girl you did business with right?  I had a huge argument that almost came to blows with a guy I was trying to buy a used Jeep Cherokee from. The title was in the name of a Chinese person and I demanded to see his national ID card and make a copy of it. He refused and ended up getting nasty with me.
