Setting up POS

[generalj]

Just wondered if anyone could give me insight on POS setup.

I have never done one but figured I might want to get information on it as I may get a job for one someday.

I understand what they are. Just never installed or configured one.

Are they hard?

Also do your clients usually have the equipment or do they usually ask you to provide one. If so what ones do you like?

What all is on a pos system usually? A front counter terminal, a backend server? etc?

Do they include a credit card processor usually? I mean as part of your setup for a job is that something you also hook up?
