1. A system used for a table in a casino, the system comprising:
a camera configured to capture an image of the table; and
a control device configured to:
recognize an amount of money placed on the table based on the image captured by the camera;
recognize an amount of chips placed on the table for being exchanged for the money even when the chips placed on the table include one or more of chips that are at least partially concealed from view of the camera:
by using an image recognition for the image captured by the camera; or
based on signals from a radio frequency identification (RFID) reader of the system that reads IDs embedded in the chips; and
compare the recognized amount of money and the recognized amount of chips to ensure that the money and the chips are exchanged at an equivalent value.
