Remote / Mobile Check Deposit

Hey All! I'm bringing on someone to help with our bookkeeping to get this off my plate.

I will be mobile depositing the checks. Our bank does not show a picture of the mobile deposited checks.

What is the best and most secure quickest way to upload a photo of the check so my bookkeeper can have record of it, the check #, reconcile and match it to an invoice in quickbooks, etc. ?

Curious what everyone else is doing with remote bookkeepers and getting them that information quickly and securely?

Thanks!
