@Nrdsb4 we had a similar setup when kids were undergrad. This was around ten years ago, we banked with USAA and kids with BoA. The mechanism to set it up at our end included a quick verification step that could only come from them. (Something like did the seventeen-cent deposit come through?)
We made more transfers to DS1, who lived off campus three of his four years. He wanted to handle the task of paying his rent, so we deposited the money to his account and let him have at it.
When they pay us for something, they just write a check.
