Question about Direct deposit and employers

I have a question regard direct deposit and employers.

I'm learning that a direct deposit form is required, to set this feature up.

Do employers accept these forms, how frequent, and do many employers follow strict regulations with this.

How does it work?

Any advice would be greatly appreciated. Do deposits, vary?

Thanks!

I guess payroll is a simplified way of putting it. But I don't think, it fixes everything.

Are you familiar with the term direct deposit. As a way of an employer paying your paycheck directly to your account, without an actual pay check, on pay day.

'I guess my questions is two parted.

1. What system is established on the employers side, to enable this feature. Is it a computer related program, or merely a business banking procedure.

and 2. What is the employee legally suppose to do, does he sign over a paper allowing them this right, or is a signature a requirement when handing an employer your direct deposit sheet?

That's all. Thanks.

Oh O.k. well thanks for the explanation. Appreciate the response.
