MDB Kit info

Updating older vending machines originally equipped with 12 or 15 pin dumb mech changer is possible.  It is accomplished using a module kit that plugs into the original changer socket.  The interface output of the kit is MDB.  This allows for card – NFC readers, Pay Range, MDB changers, and MDB validators to be installed. 

We offer two versions of MDB module kits – without and with DEX sales data.  The DEX data will report cash sales does not include sales by columns as this is not possible on older machines unless the control board is replaced.  Replacing the control board is possible but more expensive and time consuming than the module kit.  

Since the socket is now occupied by the interface kit, a MDB changer must be installed – our quote will be for a version that uses slides to dispense the coins as not advisable to use an MDB changer that uses solenoids. These older machines would typically use older pulse validators which can remain in place or be updated to an MDB model validator.

The average costs for the components needed for the update are as follows:

MDB module interface kit $199.99

MDB coin changer – refurbished Mars with 4 tubes $150.00

Card and NFC kit $299.99

A MDB validator is not always needed – the cost for a refurbished MEI series 2000 is $199.05

If you have not installed a card reader and are not familiar with replacing vending components, we offer an Assist Service.  If you have utilized a local tech to repair your vending machine in the past, they may be able to help if needed.

If you need more information please let us know the make and model of your machine(s) and we can provide more specific details.
