A "till" refers to a cash register or drawer used in retail settings to store cash and process transactions. It typically includes a compartment for coins and bills, as well as a receipt printer. Tills help businesses keep track of sales and manage cash flow efficiently. In addition to cash, modern tills often integrate with point-of-sale (POS) systems, allowing for electronic payments and inventory management. This technology streamlines the checkout process and provides valuable data for business analysis, helping retailers make informed decisions about their operations and customer preferences.
