In the fast-paced world of retail and hospitality, the “final step” of every transaction is the most critical: securing your revenue. While digital payments are on the rise, cash remains a vital part of the economy in Cambodia. The MPOS MB Series Cash Drawer is engineered to provide business owners with the perfect balance of security, durability, and seamless integration.
As a core component of the MPOS Hardware Ecosystem, the MB series is more than just a storage box it is a heavy-duty security solution built for high-volume environments.

1. Built for High-Volume Durability
A busy coffee shop or retail store might open its cash drawer hundreds of times a day. Cheap, plastic alternatives often jam or break under this pressure. The MPOS MB Series is constructed with thick, cold-rolled steel and reinforced internal mechanisms.
- Extended Lifespan: Tested for over 1 million open/close cycles, ensuring it remains smooth and reliable for years of heavy use.
- Heavy-Duty Rollers: Equipped with high-quality ball-bearing rollers that prevent the drawer from sticking, even when fully loaded with coins and bills.
2. Optimized for the Cambodian Currency Market
Managing two currencies—USD and Khmer Riel (KHR)—requires a drawer with flexible organization. The MB series features a smart internal layout designed to keep your counter organized.
- Adjustable Dividers: Easily configure the bill compartments to fit the different sizes of Riel and Dollar banknotes.
- Secure Coin Trays: Removable coin compartments allow for easy end-of-day counting and secure transport to the back office.
- Media Slots: A front-facing “media slot” allows cashiers to slide large bills, checks, or credit card slips under the drawer without opening it, adding an extra layer of security.
3. Seamless POS Integration (RJ11 Connectivity)
The MB Cash Drawer is designed to work in perfect harmony with the MPOS software and your receipt printer.
- Automatic Triggering: Using a standard RJ11 interface, the drawer connects directly to your receipt printer. The moment a cashier hits “Settle” on the MPOS screen, the drawer pops open automatically.
- Manual Override: Each unit comes with a 3-position key lock (Locked, Electronic Open, and Manual Open) to ensure you have access even during a power outage.
4. Enhanced Security Features
Protecting your daily takings is a priority. The MB series is designed to discourage internal shrinkage and external theft.
- Solid Steel Construction: Tamper-resistant casing makes it difficult to force open.
- Sleek, Low-Profile Design: Its compact footprint allows it to be tucked under the counter or integrated into a modern POS stand, keeping your cash out of sight but within reach.
