It can pass mod10, sure, but how to pre-authorize knowing funds are there and exp. Is legit.

Doing an auth is the only way to know for sure. Even if it's only for $1.
An auth is just an authorization. Your seeing if the card passes your tests and has money on it. You can do nothing after that and it'll drop. The card won't be charged and in 24 to 48 hours your transaction will disappear from their bill. Or you can capture it and get the money.
Mod10 validates a card fits a real cc's pattern. It doesn't validate the card actually has funds.
