Cash drawer

Description

A cash drawer is a secure, lockable storage compartment designed to hold and organize physical currency including banknotes and coins during retail and point-of-sale (POS) transactions. It forms an essential component of many modern POS systems, facilitating efficient cash handling, accountability, and physical security of money within commercial and institutional settings.

Cash drawers are commonly used in retail stores, restaurants, banks, pharmacies, and service centers, where cash payments are made, and precise control over cash flow is essential. Most models are designed to be connected to a receipt printer or POS terminal and open automatically when a transaction is completed.

• The exterior is typically coated with a scratch-resistant powder finish to withstand daily wear and tear.

2. Compartments and Bill Holders

• Standard drawers offer 4 to 5 bill compartments and 4 to 8 coin compartments.

• Each bill compartment features a spring-loaded metal or plastic clip to securely hold currency.
