No forklift upgrade. Clip a reader, open the deck, and run as many lanes as the night needs.
A terminal should adapt to the venue, not the other way around. TapDeck runs on the tablet already behind your bar and speaks to a reader that clips to the stand you have. That keeps the setup honest: less to buy, less to break, less to explain to a new hire.
Start with a single terminal on the main counter. When the queue earns it, add a second lane, a patio station, a roaming reader for table service. Each new terminal joins the same console, so staff and prices stay in step across every point on the floor.
Give a bartender charge and refund, give a manager the reports, and keep the drawer honest with per-operator sign-ins. The terminal remembers who did what, which makes the close quick and the questions rare.

High-contrast keys and a status line you can read across a dark room mean fewer mistakes when the venue is loudest.
When the shift is done, the terminal hands you to the numbers. Whether you searched a square login, typed square log in, asked for square sign in, or spelled out the square login dashboard, the same door opens your square dashboard. A squareup login search lands in the same place, and when you just want to square up before you cash out, the deck already has it ready.
