VMFS Payment System – MDB Compatible Card Reader Integration
VMFS vending machines are MDB protocol-ready, meaning you can integrate almost any modern card reader — from swipe and chip readers to contactless and mobile NFC systems — in minutes. No rewiring. No reprogramming. Just plug in and start accepting payments.
What Is MDB Protocol & Why It’s Important
MDB (Multi-Drop Bus) is the industry-standard protocol used in vending systems to ensure smooth communication between machines and peripheral devices. Every VMFS vending machine comes standard with an MDB-compatible port, giving you complete flexibility in payment options.
Devices You Can Connect:
Credit and debit card readers
Contactless systems like tap-to-pay
Mobile wallet readers
Coin and bill acceptors
Cashless payment kits
Why MDB Compatibility Matters:
It’s a universal standard across vending hardware
Setup is plug-and-play — no coding or special tools
No firmware changes or extra configuration
Works out of the box with most payment devices
