Master and slave combination

How does a master and slave vending machine work?

A master and slave vending machine refers to an automated vending system where two machines are linked together to operate more efficiently and cost-effectively. Here's how they work:

Master vending machine:

The master vending machine is the central control unit in this system. It has all the necessary control units and components, such as the payment system (e.g. coin validator, card terminal) required to operate both machines. Customers carry out their transactions via the master machine, which takes over the entire control and processing of payments.

Slave machine:

The slave machine is directly connected to the master machine and is controlled by it. It does not have its own control units for payments, but relies on the master machine to carry out the payment and control processes. The slave vending machine expands the product range by providing additional items that can be selected and paid for via the master vending machine.

Which location is suitable for master and slave vending machines?

Master and slave vending machines are particularly suitable for locations where a large variety of products is required and space or infrastructure for several separate vending machines is limited. Here are some ideal locations and their advantages:

Train stations and airports: these high-traffic transportation hubs provide an ideal environment for master and slave vending machines. They allow a wide range of products such as snacks, drinks and travel items to be offered efficiently without the need for a separate payment system for each machine.

Large office buildings and business parks: In large office environments, master and slave vending machines can provide a variety of products such as coffee, snacks and office supplies. Employees can quickly obtain supplies without the need for multiple vending machines with separate payment systems.

Hospitals and clinics: These locations benefit from a wide range of products, from snacks and drinks to hygiene products. A master and slave vending machine can be placed in waiting areas or near the canteen to offer a variety of items around the clock.

Universities and educational institutions/schools: In educational institutions, master and slave vending machines can offer a variety of products to meet the needs of students and staff. They are ideal for central locations such as common areas, libraries or lecture hall areas.

Shopping centers: In shopping centers, master and slave vending machines provide a flexible way to offer complementary products such as drinks, snacks and small gifts. They can be installed in high-traffic areas without taking up valuable space.

Leisure and sports facilities: In sports and leisure facilities, master and slave vending machines can offer a wide range of products, including sports drinks, snacks and accessories. They are particularly suitable for break areas or entrance areas, where they can optimally serve the needs of visitors.
