How are mobile check deposits accepted by banks if they never even get to see them up close?

Question

I always deposit my checks and the money is usually available the next day, sometimes even the same day. But, what protects these companies from fraud? How do they know the check isn’t a fake?

It’s more of a “trust system” with your bank.
Typically, they require you to put down your account number when digi.

For example: when i digi submitted my FAFSA check all 500 was approved. Normally I’d get 200 trusted.
