    Open AT or Open ON?

    I'd like to know when to use open AT or open ON. This case generates me the big dubt: "Open a POS with a shift opened on another terminal".

    Thanks in advance

    Re: Open AT or Open ON?

    I don't see 'at' in your example. I need to understand the context here if I am to attempt to answer. POS sometimes stands for Point of Sale - or cash register - which is a kind of computer terminal. Is the context a retail outlet?

    In your example 'on' is used in connection with 'terminal' and not because of 'open'. That is 'on a computer (terminal)'.
