Is there a way to set of an IPad as a point of sale system in a restaurant

I am an assistant manager in a restaurant in Juneau Aslaska and I am wondering if there is a way to set up a point of sale system using the Ipad to be able to to run credit cards, print to different printers like one to the bar and one to the kitchen also would like to know if there is a printer just for receipts that fits on a belt so the credit card never has to leave the table.
