The machines can handle everything except checks.

Ours take checks.

I don t know how they work in other areas but my local Home Depots and Ralph's Groceries have an attendant for four machines, so if you want to talk to someone during checkout, you can. They take any form of payment, including cash, which you insert into the machine. You just have to give a check to the attendant.
