What can employees be obligated to do–and pay–under a direct deposit program?

Q: My boss is getting ready to implement direct deposit and she sent out a paper for the employees to sign giving her permission to charge us 75 cents a week for her to do our direct deposits. She has told all employees that it is the bank charging us. This I know is not true. She has also told all employees they must get a bank account. Some can't because of their credit. Can she make us pay her 75 cents out of our paychecks? Florida Statute 532.04 is not clear enough on this issue. – Andrea, Florida
