The "till" in a cash drawer refers to a removable tray or compartment used to store cash, coins, and other forms of payment. It plays a crucial role in handling cash efficiently during transactions. The till is designed with sections to organize different types of bills and coins, making it easier for cashiers or business owners to manage cash flow. It can be easily taken out of the cash drawer for tasks like counting cash, reconciling transactions, or securely storing the money. The purpose of the till is to ensure accurate record-keeping and smooth cash management within a business.
