this is what code section 170(f)(8) says
(8)Substantiation requirement for certain contributions
(A)General rule
No deduction shall be allowed under subsection (a) for any contribution of $250 or more unless the taxpayer substantiates the contribution by a contemporaneous written acknowledgment of the contribution by the donee organization that meets the requirements of subparagraph (B).
(B)Content of acknowledgement
An acknowledgement meets the requirements of this subparagraph if it includes the following information:
(i)The amount of cash and a description (but not value) of any property other than cash contributed.
(ii)Whether the donee organization provided any goods or services in consideration, in whole or in part, for any property described in clause (i).
i don't understand what you mean by this
"a bank direct deposit enough proof to qualify for tax deduction"
but that does not sound like a contemporaneous written acknowledgment of the contribution by the donee organization
in addition, to be of any benefit you need to be able to itemize your deductions though there is a small charitable deduction allowed if you use the standard deduction but you still must meet the substantiation requirement.
