Introduction
PIC-031 is an interface board (MDB Pulse Converter) to convert a modern MDB payment terminal for traditional vending or ticketing machines that accepts the old-style coin/notes acceptor. It can be drink machine, a coffee machine as well.
This MDB to Pulse converter [PIC-031] is the latest design from our earlier converter design PIC-029. This new design allows the operator to configure the price, the price selection input, and the adjustment to the output pulse (pulse width and pulse number).
Advantages
- Convert legacy coin machines to modern cashless payment mode.
- Save time and cost re-designing your machine for MDB cashless devices.
- Simple to use.
- Minimum configuration required (Price and Pulse).
- Easy to operate.
Product Video Demonstration
In this demonstration, we get to see the MDB converter power up and set up the payment terminal.
The first demonstration starts with a customer selection on your vending machine, followed by a payment from a contactless credit card.
The second demonstration shows a customer waking the system with their contactless credit card, followed by a payment selection (if any), and flashing their card again for the payment.
What is MDB?
MDB stands for Multi-Drop Bus. It is a communication interface standard designed specifically for the vending machine industry. Having a common standard interface allows devices to easily connect to one another. This saves time, effort and the cost of integration.
