  No expert on POS, but some quick thoughts are:

  Bar-code scanner so the system knows what items are being bought.

  Touchscreen for a user to enter and view information, such as amount of cash received and change to give.

  Credit card reader.

  Back-office transactional database.

  Doubtless there’s many more.
